Mycotic aneurysm of the renal transplant artery

INTERNATIONAL JOURNAL OF UROLOGY, Issue 6 2006
SHIRO FUJIKATA
Abstract, A case of mycotic aneurysm secondary to septicemia is reported. A 59-year-old man with end-stage renal failure underwent renal transplantation from a living donor. On the fifteenth postoperative day, he was febrile and his arm around an entry wound of the drip infusion had infectious signs. Cultures of the blood and pus discharge grew Methicillin-resistant Staphylococcus aureus. Vancomycin was administered intravenously for 30 days. Then the existence of a mycotic aneurysm on the transplant artery was not suspected by computed tomography. After his infectious signs disappeared, examinations revealed a pseudoaneurysm measuring 4 cm in diameter at the site of anastomosis between the renal transplant and external iliac arteries by computed tomography. He has been carefully followed up with a conservative management. This is the first case of a mycotic aneurysm treated conservatively and displaying an uneventful course without rupture. [source]


Duplex Doppler sonography of transplant renal artery stenosis

JOURNAL OF CLINICAL ULTRASOUND, Issue 3 2003
Ruth Helena de Morais MD
Abstract Purpose The aim of this study was to evaluate the accuracy of duplex Doppler sonography in diagnosing transplant renal artery stenosis (TRAS) and to determine which parameter is the most reliable for making that diagnosis. Methods Over a 3-year period, we sonographically evaluated patients who were referred for investigation of possible TRAS. We investigated the following parameters: peak systolic velocity (PSV) in the external iliac and renal arteries, acceleration time and acceleration in the intrarenal arteries, acceleration time in the renal artery, resistance index, and the ratio of the PSVs in the renal and external iliac arteries. We also used MR angiography and digital subtraction arteriography to verify the degree of stenosis. After the evaluations, the patients were classified into 2 groups, 1 with and the other without significant stenosis (> 50% narrowing of the lumen) on digital subtraction arteriography. We also included a control group of patients who had undergone renal transplantation at least 6 months before, had had a good course after transplantation, had a diastolic blood pressure of 90 mm Hg or less, and were taking a maximum of 1 antihypertensive drug. Results Our study population consisted of 22 patients suspected to have TRAS (10 without and 12 with confirmed significant stenosis) and 19 control patients. We found statistically significant differences between the mean values of these 3 groups except for the PSV in the iliac artery and the resistance index in the intrarenal arteries. The most accurate parameters to use in diagnosing TRAS were an acceleration time of 0.1 second or higher in the renal and intrarenal arteries, a PSV of greater than 200 cm/second in the renal artery, and a ratio of PSVs in the renal and external iliac arteries of greater than 1.8. Conclusions Duplex Doppler sonography is an excellent method for screening patients suspected to have TRAS and can help select which of those patients should undergo digital subtraction arteriography. © 2003 Wiley Periodicals, Inc.

Mycotic pseudoaneurysm following a kidney transplant: A case report and review of the literature

PEDIATRIC TRANSPLANTATION, Issue 5 2009
Ignacio Osmán
Abstract:, Vascular complications represent a significant cause of morbidity and mortality following a kidney transplant. Pseudoaneurysms are rare, occurring in approximately 1% of cases. We present a 15-yr-old patient who received a kidney transplant in the right iliac fossa. Thirty-six days following the transplant, the patient was admitted to the hospital because of a marked increase in serum creatinine levels, arterial hypertension, scrotal edema, and lower right limb pain. The patient did not present fever or raised inflammatory markers. A pseudoaneurysm was diagnosed by means of a Doppler echography and a CT. By a selective arteriography of the right iliac artery, we placed a 8 × 5 cm stent to isolate the pseudoaneurysm, due to the high risk of an extensive defect occurring in the arterial wall. Forty-eight h later the patient underwent transplant nephrectomy. Seven days following surgery, the patient experienced febrile syndrome and therefore another CT was carried out which showed a large abscess around the stent. So we decided to perform another intervention in order to drain this abscess. Due to the extensive loss of the arterial wall where the prosthesis was largely exposed, we ligated the common iliac and external iliac arteries, removed the prosthesis and performed a femoro-femoral bypass with the usual subcutaneous positioning of the prosthesis (separate from surgical site). The stent and mural thrombus were sent for culture analysis and Candida albicans was observed. The diagnosis of a pseudoaneurysm in these types of patients continues to be considered as a surgical emergency by the majority of authors. Transplantectomy is the most frequently used treatment technique. Positioning a stent prior to transplantectomy avoids ligature of the iliac artery in the majority of cases. [source]


Endoluminal repair of distal aortic arch aneurysms causing aorto-vocal syndrome

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 10 2008
J. P. Morales
Summary Purpose:, We have evaluated the efficacy of endovascular repair of distal aortic arch aneurysms (DAAA) causing recurrent laryngeal nerve palsy. Material and methods:, Eight patients (five male and three female) with median age of 72 years (range: 59,80) presented with left recurrent laryngeal nerve palsy associated with DAAA. All patients were considered unfit for open surgery. The median aneurysm size was 5.9 cm (range: 5,7.3). Thirteen stents were deployed: eight Gore, four Endofit and one Talent. Epidural anaesthesia was used in all patients. The left subclavian artery was covered in all and the left common carotid in three who had a preliminary right to left carotid,carotid bypass. Routine follow-up (FU) was with computed tomography (CT) at 3,6 months and yearly thereafter. Results:, Exclusion of the aneurysm sac was achieved in all patients. Thirty-day mortality was 0%, with no paraplegia or stroke. Early complications included: rupture of the external iliac artery (one) and common femoral artery thrombectomy (one). One patient died of unknown cause at 17 months. The mean FU in the remaining seven patients was 21 months (range: 6,51). Aneurysm size decreased in five, was unchanged in one and increased in one. Three patients had improvement in voice quality postoperatively. One patient had a recurrent type 1 endoleak which was restented twice. No late deaths have occurred. Conclusion:, Though technically the procedures involved were more complicated, endovascular repair of DAAA causing aorto-vocal syndrome is safe and offers a realistic alternative to open surgery. Hoarseness of the voice can improve postoperatively and is associated with reduction in aortic sac diameter. [source]


Incidence and Treatment of Arterial Access Dissections Occurring during Cardiac Catheterization

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 1 2008
AMIT PRASAD M.D.
Background: Arterial access dissections may complicate cardiac catheterization and can often be treated percutaneously. The goal of this study was to examine the incidence, consequences, and the treatment of arterial access dissections at a tertiary referral hospital with an active training program. Methods: Patients experiencing arterial access dissection during coronary angiography or intervention at our institution between October 1, 2004, and January 31, 2007, were identified and their records were retrospectively reviewed. Results: Thirteen of the 3,062 consecutive patients (0.42%) had arterial access dissection during the study period. The location of the dissection was in the common femoral artery (CFA) (n = 6), the external iliac artery (EIA) (n = 6), or in an aortobifemoral graft (n = 1). Three of the six patients with CFA dissection were diagnosed during coronary angiography, and because of significant comorbidities were treated with self-expanding stents. After a mean follow-up of 7 months, they experienced no stent fracture or other complication. Six patients had EIA dissections. In one such patient, the dissection was not flow limiting and was treated conservatively. The remaining five patients underwent successful implantation of self-expanding stents, and during a mean follow-up of 9.6 months, no patient had any symptoms or events related to lower extremity ischemia. Finally, one patient had an aortobifemoral graft dissection. Due to the patient's critical condition, secondary to sepsis, his family elected to withdraw care, and he subsequently expired. Conclusions: Arterial access dissections occur infrequently during cardiac catheterization. Routine femoral artery angiography may help identify vascular access complications, often allowing simultaneous endovascular treatment, with excellent short-term outcomes. [source]


Altered course of the right testicular artery

CLINICAL ANATOMY, Issue 1 2004
M. Bülent Özdemir
Abstract An unusual course of the right testicular artery was observed during routine dissection of the posterior abdominal wall of a 60-year-old male cadaver. It arose from the abdominal aorta, inferior and posterior to the origin of the right renal artery, and passed posterior to the inferior vena cava and right renal vein; it then arched anterior to the inferior pole of the right kidney and descended anterior to the psoas major muscle, crossing anterior to the genitofemoral nerve, ureter and the proximal part of the external iliac artery. Finally, it passed to the deep inguinal ring and through the inguinal canal to enter the spermatic cord with the other constituents. The left testicular artery arose from the abdominal aorta about 1 cm higher than the right testicular artery and followed a normal course. The embryologic basis and clinical importance of this case are discussed. Clin. Anat. 17:67,69, 2004. © 2003 Wiley-Liss, Inc. [source]
