Treatment options for hydroxyurea-refractory disease complications in myeloproliferative neoplasms: JAK2 inhibitors, radiotherapy, splenectomy and transjugular intrahepatic portosystemic shunt

EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 3 2010
Elena Mishchenko
Abstract Clinical care of patients with polycythemia vera, essential thrombocythemia and myelofibrosis (MF) requires not only a broad understanding of general treatment principles but also familiarity with the management of hydroxyurea-refractory disease complications. The latter include progressive splenomegaly, symptomatic portal hypertension (e.g. ascites, variceal bleeding), pulmonary hypertension, bone pain, intractable pruritus, constitutional symptoms (e.g. fatigue, night sweats) and cachexia (i.e. loss of lean body mass, general ill health, poor appetite). Some of these symptoms are directly or indirectly related to extramedullary hematopoiesis (EMH) and others to proinflammatory cytokine excess. Results from recent clinical trials of JAK inhibitors suggest remarkable activity in MF-associated constitutional symptoms, cachexia, pruritus and hydroxyurea-refractory splenomegaly. Involved-field radiotherapy is best utilized in the setting of EMH-associated symptoms, including ascites, bone (extremity) pain and pulmonary hypertension. Splenectomy is indicated in the presence of drug-refractory splenomegaly and frequent red cell transfusion requirement. Transjugular intrahepatic portosystemic shunt is used to alleviate symptoms of portal hypertension. [source]

TIPS is a useful long-term derivative therapy for patients with Budd-Chiari syndrome uncontrolled by medical therapy

HEPATOLOGY, Issue 1 2002
Antonia Perelló
Patients with Budd-Chiari syndrome (BCS) may require treatment with portal decompressive surgery or liver transplantation. Transjugular intrahepatic portosystemic shunt (TIPS) represents a new treatment alternative, but its long-term effect on BCS outcome has not been evaluated. Twenty-one patients with BCS consecutively admitted to our unit were evaluated. The mean follow-up was 4 ± 3 years. Seven patients had nonprogressive forms and were successfully controlled with medical therapy; 1 case, with a short-length hepatic vein stenosis was successfully treated by angioplasty. All 8 patients are alive and asymptomatic. The remaining 13 patients, had a TIPS because of clinical deterioration (in one of them, because early TIPS thrombosis a successful side-to-side portacaval shunt [SSPCS] was performed) followed by an improvement in clinical condition. However, a patient with fulminant liver failure before TIPS insertion, died 4 months later and another patient with cirrhosis at diagnosis had liver transplantation 2 years later. The remaining 11 patients are alive and free of ascites. In 3 of these patients TIPS is patent after 3, 6, and 12 months. The remaining 8 patients developed late TIPS dysfunction. In two of these cases, after angioplasty and restenting, TIPS is patent after a follow-up of 9 and 80 months. In 5 other patients, recurring TIPS occlusion was not further corrected because no signs of portal hypertension were present. In conclusion, in patients with BCS uncontrolled with medical therapy, TIPS is a highly effective technique that is associated with long-term survival. [source]

Review article: recent advances in the management of bleeding gastric varices

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2006
D. TRIPATHI
Summary Gastric variceal bleeding can be challenging to the clinician. Tissue adhesives can control acute bleeding in over 80%, with rebleeding rates of 20,30%, and should be first-line therapy where available. Endoscopic ultrasound can assist in better eradication of varices. The potential risks of damage to equipment and embolic phenomena can be minimized with careful attention to technique. Variceal band ligation is an alternative to tissue adhesives for the management of acute bleeding, but not for secondary prevention due to a higher rate of rebleeding. Endoscopic therapy with human thrombin appears promising, with initial haemostasis rates typically over 90%. The lack of controlled studies for thrombin prevents universal recommendation outside of clinical trials. Balloon occluded retrograde transvenous obliteration is a recent technique for patients with gastrorenal shunts, although its use is limited to clinical trials. Transjugular intrahepatic portosystemic stent shunt is an option for refractory bleeding and secondary prophylaxis, with uncontrolled studies demonstrating initial haemostasis obtained in over 90%, and rebleeding rates of 15,30%. Non-cardioselective , -blockers are an alternative to transjugular intrahepatic portosystemic stent shunt for secondary prophylaxis, although the evidence is limited. Shunt surgery should be considered in well-compensated patients. Splenectomy or embolization is an option in patients with segmental portal hypertension. [source]

Transjugular intrahepatic portosystemic shunts: an update

LIVER TRANSPLANTATION, Issue 3 2003
Barbara Rosado
Transjugular intrahepatic portosystemic shunts (TIPS) have been used in the treatment of complications of portal hypertension. TIPS is used for the control of acute variceal bleeding and for the prevention of vericeal rebleeding when pharmacologic therapy and endoscopic therapy have failed. Patients with refractory ascites with adequate hepatic reserve and renal function who fail to respond to large volume paracentesis may be reasonable candidates for TIPS. Promising indications for TIPS are Budd-Chiari syndrome uncontrolled by medical therapy, severe portal hypertensive gastropathy, refractory hepatic hydrothorax, and hepatorenal syndrome. TIPS cannot be recommended for preoperative portal decompression solely to facilitate liver transplantation. Special care should be taken to insure proper placement of the stent to avoid increasing the technical difficulty of the transplantation procedure. The major limiting factors for TIPS success are shunt dysfunction and hepatic encephalopathy. Because shunt stenosis is the most important cause of recurrent complications of portal hypertension, a surveillance program to monitor shunt patency is mandatory. The MELD score may be useful in predicting post-TIPS survival, and also in counseling patients and their families. [source]

Transjugular intrahepatic portosystemic shunt: an analysis of outcomes

ANZ JOURNAL OF SURGERY, Issue 10 2009
Timothy P. Kurmis
Abstract Background:, Transjugular intrahepatic portosystemic shunts (TIPS) are utilized for the management of complications of portal hypertension, particularly diuretic-resistant ascites and recurrent variceal bleeding. It has also been applied in Budd,Chiari syndrome and hepatorenal syndrome. We report the results in a small series, over 9 years, from a single centre, and compare these to those published in the literature. Methods:, A retrospective case note review of 20 consecutive TIPS procedures performed at Flinders Medical Centre from January 1997 to December 2005 was completed. All indications were included in the analysis. Underlying liver disease, peri-procedure complications, relief of symptoms and patient survival were recorded. Data on type of TIPS, shunt patency and method of follow-up were recorded. Results:, Thirty-six TIPS were performed in 20 subjects. All initial TIPS attempts were successful. Indications were: refractory ascites (18), acute variceal bleeding (12) and hepatorenal syndrome (2). There were no peri-procedure deaths, however. Ninety-day mortality was 20%. Outcomes in model of end-stage liver disease score and biochemical characteristics post-TIPS were comparable to those reported. Overall, TIPS dysfunction rate was 35% at 1 year. TIPS follow-up and patency surveillance was an ad hoc combination of Doppler ultrasound and venography. Conclusion:, TIPS procedure outcomes in our centre are similar to those reported in the literature from large centres. TIPS patency rates may be improved with regular monitoring and early intervention when stenosis occurs. [source]

Treatment options for hydroxyurea-refractory disease complications in myeloproliferative neoplasms: JAK2 inhibitors, radiotherapy, splenectomy and transjugular intrahepatic portosystemic shunt

Aiming at minimal invasiveness as a therapeutic strategy for Budd-Chiari syndrome,

HEPATOLOGY, Issue 5 2006
Aurélie Plessier
The 1-year spontaneous mortality rate in patients with Budd-Chiari syndrome (BCS) approaches 70%. No prospective assessment of indications and impact on survival of current therapeutic procedures has been performed. We evaluated a therapeutic strategy uniformly applied during the last 8 years in a single referral center. Fifty-one consecutive patients first received anticoagulation and were treated for associated diseases. Symptomatic patients were considered for hepatic vein recanalization; then for transjugular intrahepatic portosystemic shunt (TIPS), and finally for liver transplantation. The absence of a complete response led to the next procedure. Assessment was according to the strategy, whether procedures were technically applicable and successful. At entry, median (range) Child-Pugh score and Clichy prognostic index were 8 (5,12), and 5.4 (3.1,7.7), respectively. A complete response was achieved on medical therapy alone in 9 patients; after recanalization in 6, TIPS in 20, liver transplantation in 9, and retransplantation in 1. Of the 41 patients considered for recanalization, the procedure was not feasible in 27 and technically unsuccessful in 3. Of the 34 patients considered for TIPS, the procedure was considered not feasible in 9 and technically unsuccessful in 4. At 1 year of follow-up, a complete response to TIPS was achieved in 84%. One- and 5-year survival from starting anticoagulation were 96% (95% CI, 90,100) and 89% (95% CI, 79,100), respectively. In conclusion, excellent survival can be achieved in BCS patients when therapeutic procedures are introduced by order of increasing invasiveness, based on the response to previous therapy rather than on the severity of the patient's condition.

Humoral and cardiac effects of TIPS in cirrhotic patients with different "effective" blood volume

HEPATOLOGY, Issue 6 2003
Francesco Salerno M.D.
The aim of this study was to evaluate the cardiac effects of transjugular intrahepatic portosystemic shunts (TIPS) in cirrhotic patients with different effective blood volume. Two-dimensional echocardiography was performed before and 7 and 28 days after TIPS insertion in 7 cirrhotic patients with PRA <4 ng/mL/h (group A, normal effective blood volume) and 15 with PRA >4 ng/mL/h (group B, reduced effective blood volume). Before TIPS, most cirrhotic patients showed diastolic dysfunction as indicated by reduced early maximal ventricular filling velocity (E)/late filling velocity (A) ratio. Patients of group B differed from patients of group A because of smaller left ventricular volumes and stroke volume, indicating central underfilling. After TIPS insertion, portal decompression was associated with a significant increase of cardiac output (CO) and a decrease of peripheral resistances. The most important changes were recorded in patients of group B, who showed a significant increase of both the end-diastolic left ventricular volumes and the E/A ratio and a significant decrease of PRA. In conclusion, these results show that the hemodynamic effects of TIPS differ according to the pre-TIPS effective blood volume. Furthermore, TIPS improves the diastolic cardiac function of cirrhotic patients with effective hypovolemia. This result is likely due to a TIPS-related improvement of the fullness of central blood volume. [source]

Acute renal failure in patients with cirrhosis: Perspectives in the age of MELD

HEPATOLOGY, Issue 2 2003
Richard Moreau
In patients with cirrhosis, acute renal failure is mainly due to prerenal failure (caused by renal hypoperfusion) and tubular necrosis. The main causes of prerenal failure are "true hypovolemia" (induced by hemorrhage or gastrointestinal or renal fluid losses), sepsis, or type 1 hepatorenal syndrome (HRS). The frequency of prerenal failure due to the administration of nonsteroidal anti-inflammatory drugs or intravascular radiocontrast agents is unknown. Prerenal failure is rapidly reversible after restoration of renal blood flow. Treatment is directed to the cause of hypoperfusion, and fluid replacement is used to treat most cases of "non-HRS" prerenal failure. In patients with type 1 HRS with very low short-term survival rate, liver transplantation is the ideal treatment. Systemic vasoconstrictor therapy (with terlipressin, noradrenaline, or midodrine [combined with octreotide]) may improve renal function in patients with type 1 HRS waiting for liver transplantation. MARS (for molecular adsorbent recirculating system) and the transjugular intrahepatic portosystemic shunt may also improve renal function in these patients. In patients with cirrhosis, acute tubular necrosis is mainly due to an ischemic insult to the renal tubules. The most common condition leading to ischemic acute tubular necrosis is severe and sustained prerenal failure. Little is known about the natural course and treatment (i.e., renal replacement therapy) of cirrhosis-associated acute tubular necrosis. [source]

Hepatic arterial buffer response in patients with advanced cirrhosis

HEPATOLOGY, Issue 3 2002
Veit Gülberg
Hepatic arterial buffer response (HABR) is considered an important compensatory mechanism to maintain perfusion of the liver by hepatic arterial vasodilation on reduction of portal venous perfusion. HABR has been suggested to be impaired in patients with advanced cirrhosis. In patients with hepatopetal portal flow, placement of a transjugular intrahepatic portosystemic shunt (TIPS) reduces portal venous liver perfusion. Accordingly, patients with severe cirrhosis should have impaired HABR after TIPS implantation. Therefore, the aim of this study was to investigate the effect of TIPS on HABR as reflected by changes in resistance index (RI) of the hepatic artery. A total of 366 patients with cirrhosis (Child-Pugh class A, 106; class B, 168; class C, 92) underwent duplex Doppler ultrasonographic examination with determination of RI and maximal flow velocity in the portal vein before and 1 month after TIPS placement. Portosystemic pressure gradient was determined before and after TIPS placement. In 29 patients with hepatofugal portal blood flow, RI was significantly lower than in 337 patients with hepatopetal flow (0.63 ± 0.02 vs. 0.69 ± 0.01; P < .001). TIPS induced a significant decrease of the RI in patients with hepatopetal flow (RI, 0.69 ± 0.01 before vs. 0.64 ± 0.01 after TIPS; P = .001) but not in patients with hepatofugal flow (RI, 0.63 ± 0.02 before vs. 0.63 ± 0.02 after TIPS; NS). This response was not dependent on the Child-Pugh class. In conclusion, our results suggest that some degree of HABR is preserved even in patients with advanced cirrhosis with significant portal hypertension. [source]

TIPS versus drug therapy in preventing variceal rebleeding in advanced cirrhosis: A randomized controlled trial

HEPATOLOGY, Issue 2 2002
Àngels Escorsell
Prevention of variceal rebleeding is mandatory in cirrhotic patients. We compared the efficacy, safety, and cost of transjugular intrahepatic portosystemic shunt (TIPS) versus pharmacologic therapy in preventing variceal rebleeding in patients with advanced cirrhosis. A total of 91 Child-Pugh class B/C cirrhotic patients surviving their first episode of variceal bleeding were randomized to receive TIPS (n = 47) or drug therapy (propranolol + isosorbide-5-mononitrate) (n = 44) to prevent variceal rebleeding. Mean follow-up was 15 months. Rebleeding occurred in 6 (13%) TIPS-treated patients versus 17 (39%) drug-treated patients (P = .007). The 2-year rebleeding probability was 13% versus 49% (P = .01). A similar number of reinterventions were required in the 2 groups; these were mainly angioplasty ± restenting in the TIPS group (90 of 98) and endoscopic therapy for rebleeding in the medical group (45 of 62) (not significant). Encephalopathy was more frequent in TIPS than in drug-treated patients (38% vs. 14%, P = .007). Child-Pugh class improved more frequently in drug-treated than in TIPS-treated patients (72% vs. 45%; P = .04). The 2-year survival probability was identical (72%). The identified cost of therapy was double for TIPS-treated patients. In summary, medical therapy was less effective than TIPS in preventing rebleeding. However, it caused less encephalopathy, identical survival, and more frequent improvement in Child-Pugh class with lower costs than TIPS in high-risk cirrhotic patients. This suggests that TIPS should not be used as a first-line treatment, but as a rescue for failures of medical/endoscopic treatments (first-option therapies). [source]

Comparison study of Doppler ultrasound surveillance of expanded polytetrafluoroethylene-covered stent versus bare stent in transjugular intrahepatic portosystemic shunt

JOURNAL OF CLINICAL ULTRASOUND, Issue 7 2010
Qian Huang MD
Abstract Objective. This prospectively randomized controlled study aimed to assess with Doppler ultrasound (US) the shunt function of expanded polytetrafluoroethylene (ePTFE)-covered transjugular intrahepatic portosystemic shunt (TIPS) stent versus bare stent and to evaluate the usefulness of routine TIPS follow-up of ePTFE-covered stents. Methods. Sixty consecutive patients were randomized for bare or covered transjugular TIPS stenting in our institution between April 2007 and April 2009. Data of follow-up Doppler US, angiography, and portosystemic pressure gradient measurements were collected and analyzed. Results. The follow-up period was 8.34 ± 4.42 months in the bare-stent group and 6.16 ± 3.89 months in the covered-stent group. Baseline clinical characteristics were similar in both groups. Two hundred three US studies were performed in 60 patients, with a mean of 3.4 per patient, and demonstrated abnormalities in 28 patients (21 bare stents, 7 ePTFE-covered stents), 19 of them (13 in bare-stent group, 6 in covered-stent group) showing no clinical evidence of recurrence. Ten of 13 patients in the bare-stent group underwent balloon angioplasty or additional stent placement, whereas only one of six patients in the covered-stent group needed reintervention for intimal hyperplasia. The average peak velocity in the midshunt of ePTFE-covered stent was 139 ± 26 cm/s after TIPS creation and 125 ± 20 cm/s during follow-up, which was significantly higher than the bare-stent group (p < 0.05). The main portal vein and hepatic artery showed higher flow velocities in the ePTFE-covered stent group than in the bare-stent group. ePTFE-covered stents maintained lower portosystemic pressure gradient than bare stents (9.5 ± 2.9 versus 13.2 ± 1.5 mmHg, p < 0.05). Conclusions. ePTFE-covered stents resulted in higher patency rates and better hemodynamics than bare stents. Routine US surveillance may not be necessary in patients with ePTFE-covered TIPS stent. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound 38:353-360, 2010 [source]

Portosystemic pressure gradient during transjugular intrahepatic portosystemic shunt with Viatorr stent graft: What is the critical low threshold to avoid medically uncontrolled low pressure gradient related complications?

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 1 2008
Hwan-Hoon Chung
Abstract Background:, Inappropriately decreased portosystemic pressure gradient (PSG) during transjugular intrahepatic portosystemic shunt (TIPS) can cause fatal complications but the critical low threshold of PSG is still not clear. The aim of the present study was to evaluate the critical low threshold of PSG during TIPS. Methods:, Sixty-six patients with cirrhosis who successfully underwent de novo TIPS with Viatorr stent grafts were studied. Medically uncontrolled low pressure gradient (LPR) complication was defined as when a patient died, or when acute transplantation or a TIPS reduction procedure was performed due to refractory encephalopathy or the deterioration of hepatic function within 3 months after the procedure. For the determination of the risk group for medically uncontrolled LPR complications, the Child-Pugh score and the model of end-stage liver disease (MELD) score showing a 100% negative predictive value was decided on as a threshold for each score. The risk group was defined when either of both scores was higher than its threshold. For the determination of a critical low post-TIPS PSG, a value of post-TIPS PSG showing the highest discrimination power on the receiver operating characteristic (ROC) curve in the risk group was decided on as a critical low threshold of PSG. The medically uncontrolled LPR complication rates of the patients with the determined threshold or lower were evaluated for the risk group. Results:, Medically uncontrolled LPR complications developed in nine patients (13.6%). Five patients died and four patients had TIPS reduction procedures. Patients with more than 10 on the Child-Pugh score or more than 14 on the MELD score were determined to be the risk group and 34 patients were included. The critical lower threshold of the post-TIPS PSG showing the highest discrimination power on the ROC curve was 5 mmHg (sensitivity 100%, specificity 72%), and the medically uncontrolled LPR complication rates of the patients with 5 mmHg or lower on the post-TIPS PSG were 56.3% (9/16) in the risk group. Conclusions:, The critical threshold of the post-TIPS PSG to avoid the medically uncontrolled LPR complications of TIPS was >5 mmHg. The PSG should not be reduced below this level in the risk group.

Circulating adiponectin reflects severity of liver disease but not insulin sensitivity in liver cirrhosis

JOURNAL OF INTERNAL MEDICINE, Issue 3 2005
S. KASER
Abstract. Background., The adipocytokine adiponectin has been proposed to play important roles in the regulation of energy homeostasis, insulin sensitivity and shows anti-inflammatory properties. Aim., In this study we investigated the role of circulating adiponectin in different chronic liver diseases, its regulation by systemic anti-tumour necrosis factor (TNF)- , treatment and its hepatic metabolism. Patients and methods., Plasma adiponectin levels were determined in 87 patients with liver cirrhosis of different aetiologies, seven patients with alcoholic steatohepatitis undergoing systemic anti-TNF- , treatment, in 11 patients with liver cirrhosis receiving transjugular intrahepatic portosystemic shunt implantation and in 21 healthy controls. Results., Adiponectin levels were significantly higher in all subjects with liver cirrhosis of different aetiologies when compared with healthy controls and increased dependent on Child-Pugh classification. In subjects with alcoholic steatohepatitis, systemic anti-TNF- , treatment caused a significant decrease in circulating adiponectin. Adiponectin concentrations were similar in portal, hepatic and peripheral veins. No correlation between adiponectin levels and insulin resistance was found in any patient group. Conclusions., Our data suggest that circulating adiponectin is increased in liver cirrhosis independent of the aetiology of liver disease. We suggest that high adiponectin levels in chronic liver disease might reflect one of the body's anti-inflammatory mechanisms in chronic liver diseases. [source]

Transjugular intrahepatic cavoportal shunt for Budd,Chiari syndrome

T Ul Haq
Summary Budd,Chiari syndrome (BCS) is characterized by obstruction of the hepatic venous outflow tract. Therapeutic options for BCS are limited. We report a case of a 21-year-old woman with protein S and C deficiency with gross ascites. Treatment with transjugular intrahepatic portosystemic shunt (TIPS) was attempted, which revealed occluded hepatic veins, so transcaval TIPS was performed. No serious procedure-related complication occurred. After successful shunt creation, the patient's symptoms subsided and she was discharged and followed up for 6 months. [source]

Reversible Cytotoxic Edema in a Cirrhotic Patient Following TIPS

JOURNAL OF NEUROIMAGING, Issue 4 2009
James R. Babington MD
ABSTRACT The authors report the magnetic resonance imaging (MRI) findings in a 52-year-old man with cirrhosis from chronic hepatitis C who developed episodic acute hepatic encephalopathy Type C following placement of transjugular intrahepatic portosystemic shunt (TIPS). Brain MRI revealed hyperintense T2 signal and restricted diffusion distributed through the cerebral cortex. The patient's mentation improved with treatment of his hyperammonemia. Brain MRI performed 5 months later revealed diffuse cerebral atrophy and new areas of hyperintense T2 signal in the cerebral white matter. The cortical signal abnormalities and low apparent diffusion coefficient values on the initial MRI resolved with exception of a mild amount of hyperintense FLAIR signal in the cingulate cortex. Acute hepatic encephalopathy following portosystemic shunting,either from placement of TIPS or from development of spontaneous shunts,is a widely recognized complication of portal hypertension and cirrhosis. We report MRI findings of reversible cytotoxic edema in a patient with acute hepatic encephalopathy following placement of TIPS. [source]

Systematic review: portal vein thrombosis in cirrhosis

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2010
E. A. TSOCHATZIS
Aliment Pharmacol Ther 31, 366-374 Summary Background, As current imaging techniques in cirrhosis allow detection of asymptomatic portal vein thrombosis during routine ultrasonography, more patients with cirrhosis are diagnosed with portal vein thrombosis. Although a consensus on noncirrhotic extra-hepatic portal vein thrombosis has been published, no such consensus exists for portal vein thrombosis with cirrhosis. Aim, To perform a systematic review of nonmalignant portal vein thrombosis in cirrhosis in terms of prevalence, pathogenesis, diagnosis, clinical course and management. Methods, Studies were identified by a search strategy using MEDLINE and EMBASE. Results, Portal vein thrombosis is encountered in 10,25% of cirrhotics. In terms of pathophysiology, cirrhosis is no longer considered a hypocoagulable state; rather than a bleeding risk in cirrhosis, various clinical studies support a thrombotic potential. Clinical findings of portal vein thrombosis in cirrhosis vary from asymptomatic disease to a life-threatening condition at first presentation. Optimal management of portal vein thrombosis in cirrhosis is currently not addressed in any consensus publication. Treatment strategies most often include the use of anticoagulation, while thrombectomy and transjugular intrahepatic portosystemic shunts are considered second-line options. Conclusions, Portal vein thrombosis in cirrhosis has many unresolved issues, which are often the critical problems clinicians encounter in their everyday practice. We propose a possible research agenda to address these unresolved issues. [source]

Outcomes of transjugular intrahepatic portosystemic shunt through the left branch vs. the right branch of the portal vein in advanced cirrhosis: a randomized trial

LIVER INTERNATIONAL, Issue 7 2009
Lei Chen
Abstract Background/Aims: The transjugular intrahepatic portosystemic shunt (TIPS) is technically divided into TIPS through the left branch of the portal vein (TIPS-LBPV) and TIPS through the right branch of the portal vein (TIPS-RBPV). In order to compare their advantages and disadvantages, this randomized, controlled trial was designed to investigate their outcomes in advanced cirrhotic patients. Methods: Seventy-two patients were randomly placed into TIPS-LBPV (36 patients) and TIPS-RBPV (36 patients, with four failures) groups, and they were prospectively followed for 2 years after TIPS implantation. Results: Patients who underwent the two different kinds of TIPS were balanced during recruitment for this study. The incidences of overall encephalopathy and de novo encephalopathy in the TIPS-LBPV group were significantly lower than that of the TIPS-RBPV group during follow-up (P=0.036 and 0.012 respectively). The incidences of rebleeding or re-intervention and improvement of ascites were similar between groups (P>0.05). Patients undergoing TIPS-RBPV required more rehospitalization and incurred more costs than those who underwent TIPS-LBPV (P=0.030 and 0.039 respectively). There was no significant difference between the two groups in survival based on a survival curve constructed according to the Kaplan,Meier method (P>0.05). Conclusion: Patients undergoing TIPS-LBPV had a lower incidence of encephalopathy, less rehospitalization and lower costs after TIPS implantation compared with patients undergoing TIPS-RBPV.

Prognosis of hepatorenal syndrome , has it changed with current practice?

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2004
P. Angeli
Summary The Consensus Conference on Hepatorenal Syndrome (HRS) organized by the International Ascites Club in 1994 redefined HRS, introduced new diagnostic criteria that are now widely accepted, and proposed the distinction between two types of HRS: type 1 and type 2. Before the introduction of the new therapeutic options, the median survival of patients with type 1 HRS was only 1.7 weeks, and 6,12 months in patients with type 2 HRS. Liver transplantation (LT) was the first therapeutic option to change the prognosis of cirrhotic patients with HRS and 5-year survival after LT in patients with HRS is only slightly less than that of transplanted patients without HRS and markedly increased when compared to survival in nontransplanted patients with HRS. Nevertheless, a large proportion of patients die before LT is possible because of the poor prognosis of HRS and the prolonged waiting times in most transplant centres. Other therapeutic approaches were therefore developed to increase survival in patients with HRS. Vasoconstrictors and transjugular intrahepatic portosystemic shunt (TIPS) are the most promising. The administration of vasoconstrictors together with albumin has been shown to reverse type 1 HRS and even to completely normalize renal function in 60,70% of treated patients. To date, four studies assessing TIPS in the management of type 1 HRS have been reported and TIPS insertion was technically successful in all of them. Given the shortage of donors for LT, vasoconstrictor therapy and TIPS strategies may be considered as a bridge to LT in patients with type 1 HRS. [source]

Use of splenic artery embolization to relieve tense ascites following liver transplantation in a patient with paroxysmal nocturnal hemoglobinuria

LIVER TRANSPLANTATION, Issue 11 2007
Charissa Y. Chang
Recurrent venous thrombosis following liver transplantation for Budd-Chiari syndrome is common, particularly in the setting of an underlying myeloproliferative disorder. We describe a patient who developed refractory ascites due to portal vein thrombosis following liver transplantation for Budd-Chiari syndrome in the setting of paroxysmal nocturnal hemoglobinuria. Extensive portal vein thrombosis, dense abdominal adhesions, and portosystemic collaterals precluded the use of a transjugular intrahepatic portosystemic shunt or surgical portosystemic shunt to manage the patient's ascites. Splenic artery embolization to decrease portal hypertension was performed, and this resulted in complete resolution of ascites. This case demonstrates the successful use of splenic artery embolization to manage ascites due to portal vein thrombosis following liver transplantation. Splenic artery embolization may be considered as an alternative option for the management of refractory ascites due to portal hypertension in patients who are unable to undergo safe transjugular intrahepatic portosystemic shunt or surgical shunt placement.

Vitamin A toxicity: When one a day doesn't keep the doctor away

LIVER TRANSPLANTATION, Issue 12 2006
Rekha Cheruvattath
Vitamin A toxicity has been reported to cause severe liver disease and, occasionally, liver failure. Herein we present the case of a 60-year-old male with symptoms of muscle soreness, alopecia, nail dystrophy, and ascites. He continued to deteriorate with the development of refractory ascites, renal insufficiency, encephalopathy, and failure to thrive. A liver biopsy demonstrated presence of Ito cells and vacuolated Kupffer cells without the presence of cirrhosis. His clinical history revealed ingestion of large doses of vitamin A. His worsening clinical situation ruled out the possibility of a transjugular intrahepatic portosystemic shunt. The patient underwent orthotopic liver transplantation with resolution of symptoms. Vitamin A toxicity should be considered in the differential diagnosis of noncirrhotic portal hypertension. In conclusion, liver transplantation is a valid option if no improvement occurs in spite of cessation of the medication. Liver Transpl 12:1888,1891, 2006. © 2006 AASLD. [source]

Two-stage total hepatectomy and liver transplantation for acute deterioration of chronic liver disease: A new bridge to transplantation

LIVER TRANSPLANTATION, Issue 4 2004
Michael J. Guirl
Two-stage total hepatectomy and liver transplantation has been reported for acute liver disease such as fulminant hepatic failure, primary graft failure, severe hepatic trauma, and spontaneous hepatic rupture secondary to hemolysis, elevated liver function tests, low platelets syndrome, and preeclampsia. This is the first report of patients with cirrhosis to undergo a 2-stage total hepatectomy and liver transplantation. From 1984 to 2002, our institution performed 2008 orthotopic liver transplantations. We identified 4 patients with chronic liver disease who underwent a 2-stage hepatectomy and liver transplantation. This is a retrospective review of these 4 patients and a review of the literature on this procedure. All 4 patients were young men with an age range of 29,31 years and had underlying cirrhosis as well as a previous transjugular intrahepatic portosystemic shunt (TIPS)procedure. Acute decompensation fulfilling Ringes' criteria for toxic liver syndrome secondary to an upper gastrointestinal bleed occurred in all patients. The approximate average time between hepatectomy and liver transplantation was 20 hours (range: 8,42 hours). In all cases, the explanted liver showed histological changes of acute hepatic necrosis within the background of cirrhosis. After hepatectomy, vasopressor requirements were well documented in 2 patients. For 1 patient, there was a clear improvement in their hemodynamic status. The mean hospital stay of the 4 patients was 63 days. All patients were discharged from the hospital and are alive and well with adequate liver function at 6 to 37 months follow-up. Two-stage total hepatectomy and liver transplantation may be a life-saving procedure in highly selected cirrhotic patients with acute hepatic decompensation and multiorgan dysfunction.

Liver transplantation complicated by embedded transjugular intrahepatic portosystemic shunt: A new method for portal anastomosis,a surgical salvage procedure

LIVER TRANSPLANTATION, Issue 2 2000
Robert R. Hutchins
A transjugular intrahepatic portosystemic shunt (TIPS) is an increasingly used method of treating variceal bleeding from portal hypertension. Many patients are subsequently listed for transplantation, which may be complicated by malposition of the inferior end of the TIPS stent. This report details such a case and offers a surgical technique to salvage this situation. [source]
