abstract: introduction & objective: in patients with chronic renal failure who need chronic hemodialysis, av fistula is one of the most proper ways of vascular access. the aim of this study was to assess the patency and complications of av fistulas in patients with chronic hemodialysis. materials & methods: in this descriptive study 82 patients with chronic renal failure, who underwent av fistu...

For the nephrologist and surgeon, maintaining vascular access is a significant challenge in hemodialysis (HD), because the portal is vulnerable to infection, stenosis, and thrombus. Vascular access options for HD include the placement of arteriovenous (AV) fistulas, AV grafts, and double-lumen, cuffed central vein catheters. Catheter use is generally associated with higher rates of infection an...

PURPOSE Thrombosis of native arteriovenous (AV) fistula is an important cause of complications in hemodialysis (HD) patients. The purpose of this study was to investigate the usefulness of measuring circulating fibroblast growth factor-23 (FGF-23) level and paraoxonase-1 (PON1) lactonase activity as potential predictors of native AV fistula thrombosis in chronic HD patients. METHODS This stud...

OBJECTIVES THE AIM OF THE STUDY WAS: Is primary Arterio-venous fistula the vascular access of choice for adequate dialysis and better patient outcome in end stage renal disease. MATERIALS AND METHODS The present study was done in the department of cardiovascular and thoracic surgery at Sher-i-Kashmir institute of medical sciences, Soura, Srinagar Kashmir. Native Arterio-Venous (AV) fistulas w...

Spinal arteriovenous shunts (AV shunts; including spinal AV fistulas and AV malforma‐ tions) are heterogeneous entities that can render devastating neurological sequelae by hemorrhage (hematomyelia, subarachnoid hemorrhage, and subdural/epidural hemato‐ ma), venous congestion, mass effect, and vascular steal [1-5]. These lesions have been challenging entities to treat because of their complicat...

Background. Traumatic arteriovenous (AV) fistula is considered to be a pathologic communication between the arterial and venous systems following injury caused mostly by firearms, sharp objects or blasting agents. Almost 50% of all traumatic AV fistulas are localized in the extremities. In making diagnosis, besides injury anamnesis data, clinical image is dominated by palpable thrill and auscul...

Purpose. Our objective was to evaluate the outcome of percutaneous transluminal angioplasty (PTA) and particularly rePTA in a failing arteriovenous fistula (AV-fistula). Are multiple redilations worthwhile? Patients and Methods. All 159 stenoses of AV fistulas that were treated with PTA, with or without stenting, during 2008 and 2009, were included. Occluded fistulas that were dilated after suc...

Abstract Aims: To report the endovascular treatment and complications of intracranial spinal dural arteriovenous (AV) fistulas. Methods: A retrospective analysis 863 cases with AV fistulas was completed in nationwide registry study Japanese Society Neuroendovascular Therapy. Results: Treatments included transarterial/transvenous embolization (TAE/TVE), open surgery, stereotactic radiation, thei...

BACKGROUND Haemodialysis is the primary mode of renal replacement therapy for patients of end stage renal disease. The most important determinant for effective haemodialysis is a reliable vascular access. Arterio-venous (AV) fistula is the closest to be an ideal long-term haemodialysis vascular access. The creation of fistulas or grafts is recommended before starting haemodialysis, this study w...
