Iliac Vein (iliac + vein)
Kinds of Iliac Vein Selected AbstractsPercutaneous Retrieval of a Wallstent from the Pulmonary Artery Following Stent Migration from the Iliac VeinJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2002RAJIV M. ASHAR M.D. Wallstents are being used increasingly in conjunction with balloon dilatation for treatment of iliac vein stenosis. Stent misplacement or migration is a complication of the procedure, and may be symptomatic and warrant repositioning or removal. We report the case of a patient whose iliac vein stenosis was managed with two overlapping Wallstents and was complicated by embolization of one stent into the right ventricle (RV) and the other to the pulmonary artery (PA). This article illustrates percutaneous endovascular removal of a migrated stent from the PA using a jugular and femoral approach. [source] Effect of amino acid and glucose administration following exercise on the turnover of muscle protein in the hindlimb femoral region of ThoroughbredsEQUINE VETERINARY JOURNAL, Issue S36 2006A. MATSUI Summary Reasons for performing study: In man, muscle protein synthesis is accelerated by administering amino acids (AA) and glucose (Glu), because increased availability of amino acids and increased insulin secretion, is known to have a protein anabolic effect. However, in the horse, the effect on muscle hypertrophy of such nutrition management following exercise is unknown. Objectives: To determine the effect of AA and Glu administration following exercise on muscle protein turnover in horses. We hypothesise that administration of AA and Glu after exercise effects muscle hypertrophy in horses, as already shown in man and other animals. Methods: Measurements of the rate of synthesis (Rs) and rate of degradation (Rd) of muscle protein in the hindlimb femoral region of thoroughbred horses were conducted using the isotope dilution method to assess the differences between the artery and iliac vein. Six adult Thoroughbreds received a continuous infusion of L-[ring- 2H5]-phenylalanine during the study, the stable period for plasma isotope concentrations (60 min), resting periods (60 min), treadmill exercise (15 min) and recovery period (240 min). All horses were given 4 solutions (saline [Cont], 10% AA [10-AA], 10% Glu [10-Glu] and a mixture with 10% AA and 10% Glu [10-Mix]) over 120 min after exercise, and the Rs and Rd of muscle protein in the hindlimb measured. Results: The average Rs during the 75,120 min following administration of 10-Mix was significantly greater than for the other solutions (P<0.05). The second most effective solution was 10-AA, and there was no change in Rs after 10-Glu. Conclusions: Administration of AA following exercise accelerated Rs in the hindlimb femoral region, and this effect was enhanced when combined with glucose, because of increasing insulin secretion or a decreased requirement for AA for energy. Potential relevance: Further studies are required regarding the effect on muscle hypertrophy of supplementing amino acids and glucose in the feed of exercising horses. [source] Successful renal transplantation in the right iliac fossa 2 years after serious deep venous thrombosis in a patient with systemic lupus erythematosusINTERNATIONAL JOURNAL OF UROLOGY, Issue 10 2005NORIHIKO TSUCHIYA Abstract Deep venous thrombosis (DVT) possibly occurs in the perioperative period, and induces serious complications such as a pulmonary embolism. On the other hand, allograft renal vein thrombosis leads to a high incidence of graft loss. We experienced a case in which a serious DVT occurred prior to renal transplantation; however, a successful renal transplantation in the right iliac fossa was performed after 2 years of anticoagulant therapy. It is suggested that the external iliac vein even after suffering from DVT can be anastomosed to an allograft vein successfully, when enough blood ,ow or a lower venous pressure is con,rmed. However, one should be aware of the risk factors and the adequate management of thrombosis in renal transplantation because of the serious complications of DVT and the poor prognosis of allograft vein thrombosis. [source] Unusual hepatic-portal-systemic shunting demonstrated by Doppler sonography in children with congenital hepatic vein ostial occlusionJOURNAL OF CLINICAL ULTRASOUND, Issue 4 2004Maha Barakat MD Abstract Purpose This report describes unusual changes in the hepatic vasculature in 3 children presenting with upper gastrointestinal hemorrhage. Methods The study included 3 children (ages 5,8 years) who presented with hematemesis. All had mild hepatosplenomegaly and normal liver function. Esophageal varices were demonstrated in all on upper endoscopy. Color and spectral Doppler sonography was performed to assess the hepatic vasculature, including the hepatic veins (HVs), portal vein (PV), hepatic artery (HA), and inferior vena cava (IVC). Results The HVs were all patent but with ostial occlusion at the point of their communication with the IVC. Complete flow reversal was shown inside the HVs, with blood draining into collateral vessels at the liver surface and paraumbilical vein. In one patient, the paraumbilical vein could be traced to its communication with the right external iliac vein. In all children, the direction of flow in the PV, HA, and IVC was normal. After endoscopic sclerotherapy, all children were shown to be in good general condition and to have normal liver function for a follow-up period of 15,36 months. Conclusions Ostial occlusion of the HV is a rare cause of hepatic outflow obstruction in children. Doppler sonography is a valuable, noninvasive imaging technique for evaluation of the hepatic vasculature and the accompaning shunting pathways in such cases. © 2004 Wiley Periodicals, Inc.

It is caused by an anatomic anomaly in which the right common iliac artery overlies the left common iliac vein causing mechanical compression. Subsequent endothelial changes within the vessels have the potential to spur thrombus formation. Aggressive diagnostic and therapeutic interventions must be implemented upon suspicion to avoid long-term complications. We report on a 19 year old male who presented with ICS. We discuss the clinical presentation, diagnosis, and current treatment options. Journal of Hospital Medicine 2010. © 2010 Society of Hospital Medicine. [source] Early phase of reperfusion of human kidney allograft does not affect an erythrocyte anti-oxidative systemNEPHROLOGY, Issue 5 2006LESZEK DOMA SUMMARY: Background: Generation of reactive oxygen specimens is the basic mechanism leading to ischaemia/reperfusion injury of the kidney graft. Oxygen burst is a trigger for sophisticated biochemical changes leading to generation of oxygenated lipids and changes in microcirculation, which recruit recipient's neutrophils and contribute to delayed graft function. It has been shown that the free radicals generation correlates with the activity of anti-oxidative system. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione (GSH) are involved in protection against free radicals. Aim: To examine the activity of erythrocyte anti-oxidative system during reperfusion of the transplanted kidney allograft. Methods: The study included 40 renal transplant recipients. Blood was taken from the iliac vein before transplantation and from the graft's renal vein immediately, as well as 2 and 4 min after total reperfusion. The authors assessed the process of reperfusion using ThermaCAM SC500 termovision camera. Spectrophotometric methods were used to measure superoxide dismutase, glutathione peroxidase and catalase activity as well as glutathione concentrations in erythrocytes. Results: There were no statistically significant differences in the activities of superoxide dismutase, catalase and glutathione peroxidase as well as glutathione concentrations during the first 4 min after total graft reperfusion. Nevertheless, there was a positive correlation between the activity of superoxide dismutase and glutathione peroxidase. Conclusion: The results suggest that the erythrocyte anti-oxidative system is stable during the early phase after reperfusion. An association between some anti-oxidative enzymes was noted. [source] Early transient leg swelling at the side of renal transplant in two childrenPEDIATRIC TRANSPLANTATION, Issue 1 2006L. Koster-Kamphuis The swelling was located at the side of the renal transplant. The swelling was caused by the compression of the iliac vein by the renal transplant combined with perirenal fluid collection. Doppler flow studies allow the exclusion of thrombosis as an explanation for the swelling. An aggressive treatment should be avoided. However, anticoagulation is required. [source] A new experimental inbred Wistar rat varicocele model: anatomy of the left spermatic vein and the effect on histologyANDROLOGIA, Issue 1 2008Y. Zhang Summary Because of venous anatomical differences between rats and humans and the personal interpretation of these differences, there is neither consistent animal prototype nor consistent results in the study of varicocele. We established a new substrain of Wistar inbred rats, of which the left testis vein has no significant branches to the common iliac vein up pampiniform plexus, but instead enters the left renal vein directly (similar to humans) and used them to create experimental varicocele model by partial ligation of the left renal vein. One month later, the predominant lesion of the left testis in induced group was spermatogenic arrest at the spermatid and preliminary spermatocyte phases, and considerable interstitial and Sertoli cell vacuolation. The right testis also showed spermatogenic arrest. Most important, the characteristics of the lesions differed in both testes, with the left testis having more severe lesions. Allowing for the unique anatomy of the left spermatic vein, the standard of the surgical procedure, the high rate of varicocele induction, and identical histological alteration as occurs in humans, we believe that this inbred Wistar rat substrain is suitable for the creation of an experimental varicocele model, which has promise for practical application in humans. [source] Avulsion of ascending lumbar and iliolumbar veins in anterior spinal surgery: An anatomical studyCLINICAL ANATOMY, Issue 5 2007G. Sivakumar Abstract To expose the disc between the 4th and 5th lumbar vertebrae in anterior spinal surgery, left to right retraction of inferior vena cava and aorta is required. This manoeuvre can be complicated by venous haemorrhage that, in most cases, is due to avulsion of the left ascending lumbar vein (ALV) or the left iliolumbar vein (ILV). We dissected 23 embalmed cadavers to assess the factors that contribute to the risk of tearing these two veins during retraction. We describe a triangular region that should help surgeons in identifying the ALV and ILV. This triangle is defined by the lateral border of the common iliac vein, the medial border of the psoas major muscle, and the superior end-plate of the L5 vertebral body. We observed that 3 cm between the termination of the left ALV, or a common stem with the ILV, and the termination of the common iliac vein is the critical distance, less than which the risk of venous avulsion is highest. Although the sample considered is small, our study seems to suggest that male patients tend to have a higher risk of venous avulsion than female patients. Clin.

[source] Catheter-directed therapy for DVT after pancreas transplantationCLINICAL TRANSPLANTATION, Issue 6 2007Harish D Mahanty Abstract:, Introduction:, Iliac vein deep venous thrombosis (DVT) ipsilateral to the pancreas transplant can lead to severe leg edema and compromise graft function. Treatment modalities for iliac vein DVT in the pancreas transplant recipient are limited. Methods:, Medical records of patients receiving pancreas transplants at a single center from November 1989 to July 2003 were reviewed retrospectively, identifying patients with iliac vein DVT. There were 287 pancreas transplants performed during this time. Pancreas transplantation in all recipients was performed in the right iliac fossa with the arterial supply consisting of a donor iliac artery Y interposition graft. Systemic venous drainage was to the iliac vein. Exocrine drainage was enteric or to the bladder. Results:, Four (1.4%) cases of iliac DVT were identified. All patients manifested lower extremity edema ipsilateral to the pancreas transplant. DVT was detected by ultrasound on days 4, 5, 13, and 60 post-transplant. In all cases, the iliac vein caudad to the pancreatic venous anastomosis was noted to be stenotic. Management involved balloon dilatation and endovascular stent placement in one patient, thrombolysis with tissue plasma antigen (t-PA) followed by stent placement in one patient, and percutaneous mechanical thrombectomy in two patients. All patients had improvement in leg edema and two patients continue to have good pancreatic allograft function. Conclusions:, Iliac DVT is a rare complication of pancreas transplantation that usually develops in an area of stenosis caudad to the pancreatic venous anastomosis. Catheter-based treatment modalities with use of endovascular stents for treatment of underlying stenoses can serve as an adjunct in treating these complications. [source] Activity of CuZn-superoxide dismutase, catalase and glutathione peroxidase in erythrocytes in kidney allografts during reperfusion in patients with and without delayed graft functionCLINICAL TRANSPLANTATION, Issue 1 2006L Doma Abstract:, Background:, Generation of reactive oxygen species (ROS) is the main mechanism involved in the ischemic/reperfusion damage of the transplanted organ. Oxygen burst is a trigger for complex biochemical events leading to generation of oxygenated lipids and changes in microcirculation. Many markers have been researched to prove the presence of ROS in the transplanted tissue. Some of them, like superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) are considered to play a major role in graft protection against oxygen stress during reperfusion. Methods:, The aim of this study was to examine the changes of SOD1, CAT and GPx activity in erythrocytes during the first minutes after total graft reperfusion. Forty patients undergoing kidney transplantation at our center were assigned to two groups: with or without delayed graft function (DGF). Before anastomosing kidney vessels with recipient's iliac vessels, the ,0' blood sample was taken from the iliac vein. Next blood samples I, II and III were taken from the graft's renal vein. The reperfusion of the transplanted kidney was evaluated precisely with the thermovision camera. Erythrocyte SOD1, CAT and GPx activity was measured with a spectrophotometric method. Results:, We did not observe statistically significant changes in SOD1, CAT and GPx activity in erythrocytes during the early phase of reperfusion in patients with and without DGF. Conclusions:, Erythrocyte-antioxidative system in graft's vein remain stable during the early phase of reperfusion. The results of the study suggest that further studies on extracellular enzymes are required for the assessment of antioxidant system in the conditions of ischemia/reperfusion. [source] Our experience with third renal transplantation: Results, surgical techniques and complicationsINTERNATIONAL JOURNAL OF UROLOGY, Issue 12 2007Mohammad Hossein Nourbala Background: Despite the popularity of kidney transplantation in the current era, second and third kidney transplantation are not yet widely accepted and practiced. Each center has its own regulations and experiences and there is no accepted protocol for third kidney transplantation. We report here our 15 years of experience with third kidney transplantation. Methods: This is a report of all the third kidney transplantations performed in Baqiyatallah Hospital, Tehran, Iran, between 1991 and 2006. Demographic data, surgical techniques, complications and outcomes are reported. Results: Of the nine third kidney transplant patients, six were male. The median age was 43 years (32,52). All of the patients received kidney from living donors. All operations were performed by a midline incision and the grafts were placed at the midline, in the intraperitoneal space. For arterial anastomosis, we used internal iliac, right common iliac and both the right external iliac and inferior mesenteric artery in 4, 4 and 1 case(s), respectively. For venous anastomosis, we used vena cava, common iliac and external iliac veins in 3, 5 and 1 case(s), respectively. During the follow up period (38 months), 6 grafts (66.6%) were functioning. None of the graft rejections were due to surgical complications. Wound dehiscence occurred in two patients. No other surgical complications including infection, lymphocele or hemorrhage were observed. Conclusion: Third kidney transplantation is a field that has not been fully explored. The rate of complications seems to be not much higher than the first transplantation. Defining a standard protocol seems necessary. [source] Pacemaker Lead Extraction with the Needle's Eye Snare for Countertraction via a Femoral ApproachPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 7 2002DIDIER KLUG KLUG, D., et al.: Pacemaker Lead Extraction with the Needle's Eye Snare for Countertraction via a Femoral Approach. Femoral approach pacemaker lead extraction is described as a safe and efficacious procedure. When the lead can not be removed from its myocardial insertion, the "Needle's eye snare" has become available, and it allows a femoral approach traction associated with a countertraction . Between May 1998 and May 2000, 222 lead extraction procedures were performed in 99 patients using the femoral approach. This article reports the results of the 70 lead extractions requiring the use of the Needle's eye snare for femoral approach countertraction in 39 patients with a total of 82 leads. The indications were infection, accufix leads and lead dysfunction in 56, 1 and 6 leads, respectively. The age of the leads was 113 ± 56 months. Sixty-one (87.2%) leads were successfully extracted, the extraction was incomplete in 3 (4.3%) cases and failed in 6 (8.5%) cases. The failures were due to leads totally excluded from the venous flow for four leads, the impossibility of advancing the 16 Fr long sheath through the right and left iliac veins for one lead and one traction induced a nontolerated ventricular arrhythmia. In these cases, an extraction by a simple upper traction had been attempted in another center several months before. The complications included two deaths and one transient ischemia of the right inferior limb. Despite the selection of a series of leads for which an extraction by a simple traction on the proximal end of the lead was impossible or unsuccessful, femoral countertraction seems to be a safe and efficacious procedure. The failure of this technique occurred in patients with damaged leads due to a previous extraction procedure performed in centers with limited experience in lead extraction. [source] Successful management of bleeding with recombinant factor VIIa (NovoSeven®) in a patient with Burkitt lymphoma and thrombosis of the left femoral and left common iliac veinsPEDIATRIC BLOOD & CANCER, Issue 3 2007Abstract We present the case of an 18-year-old female with Burkitt lymphoma involving the intra-abdominal and inguinal lymph nodes. The tumor had invaded the left femoral and common iliac veins causing secondary thrombosis and vessel occlusion. Chemotherapy and anticoagulant treatment resulted in mild thrombocytopenia and a prolonged prothrombin time, respectively, which exacerbated postoperative bleeding following surgical removal of a deep inguinal necrosis. After 6 days, bleeding combined with epistaxis was considered to be life threatening and anticoagulant reversal with recombinant factor VIIa was successfully performed. The patient has since achieved complete remission and subsequent antithrombotic therapy has resolved the vascular occlusion. Pediatr Blood Cancer 2007;49:332,335. © 2006 Wiley-Liss, Inc.
