Venous injury and attendant venous stenosis are major contributors to the failure of hemodialysis vascular accesses. This report describes the presence of neoangiogenesis in the intima and adventitia of the venous limb of an arteriovenous (AV) fistula in the rat, the latter induced by creating an aortocaval fistula. Immunohistochemistry of the venous limb demonstrated the presence of c-Kit-posi...

OBJECTIVE To review published reports on arterio-ureteral fistula. METHOD Literature search. RESULTS Eighty cases were identified. Primary fistulas were mainly seen in combination with aortoiliac aneurysmal disease. Secondary fistulas were seen after pelvic cancer surgery, often with radiation, fibrosis and ureteral stenting or after vascular surgery with synthetic grafting. The dominating ...

Background and Objectives: Arteriovenous fistula is a popular vascular access method for surgical treatment of hemodialysis patients. The method, however, is associated with a high rate of early failure varying in the range of 20-60%. Predicting early Arteriovenous fistula failure and its risk factors can help reduce its incidence, its hospitalization rate, and associated costs. In this study, ...

Introduction: The number of people with diabetes is increasing in every country. Recent estimates put the prevalence at 8.3% of adults, with a predicted rise to 10.1 in 2035 [1]. Although less than 1% of patients with diabetes require definitive haemodialysis, this still represents a significant number who may require arteriovenous fistula creation. Presentation: We report a case of IMN occurri...

BACKGROUND AND OBJECTIVES Vascular access standards are predominantly based on older, single-center reports; however, the hemodialysis population has changed dramatically and primary arteriovenous fistula failure is a huge problem. This prospective, multicenter study used standardized definitions to analyze patency rates and potential risk factors that affect functional patency and late arterio...

BACKGROUND Many arteriovenous fistula (AVF) fail prior to use due to lack of maturation or thrombosis. Determining vascular function prior to surgery may be helpful to predict subsequent AVF success. This is a feasibility study to describe the vascular function in a cohort of chronic kidney disease (CKD) patients who are awaiting AVF creation. METHODS A prospective cohort of 28 CKD patients e...

OBJECTIVE To modify the technique of basilic vein transposition for vascular accesss for haemodialysis aiming at better maturation rate, longer survival of fistula and lesser complications. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Shaikh Zayed Hospital and Omer Hospital, Lahore, from February 2008 to July 2011. METHODOLOGY Patients referred for basilic vein transposition for ...

as a permanent access. 3 A multidisciplinary vascular access care program established by Gambro Healthcare has proven effective in implementing the National Kidney Foundation Dialysis Outcomes Quality Initiative (DOQI) guidelines for vascular access. Since 1996, a multidisciplinary team approach has been used in our Renal Care Group dialysis program in the Olympia, Wash., area to increase the u...

The growing proportion of individuals suffering from chronic kidney disease has considerable repercussions for both kidney specialists and primary care. Progressive and permanent renal failure is most frequently treated with hemodialysis. The efficiency of hemodialysis treatment relies on the functional status of vascular access. Determining the type of vascular access has prime significance fo...

Although endovascular transcatheter embolization of arteriovenous fistulas is minimally invasive, the torrential flow prevailing within a fistula implies the risk of migration of the deployed embolization devices into the downstream venous and pulmonary circulation. We present the endovascular treatment of a giant postnephrectomy arteriovenous fistula between the right renal pedicle and the res...
