The arteriovenous fistula (AVF) has been a mainstay of hemodialysis treatments and the preferred access route since its inception in the 1960s, due to its longevity and resistance to infection. However, the AVF is not benign. There is significant primary failure, as well as cardiac, vascular, and other, less well recognized, complications. Together, they represent toxicity, to which considerabl...

We present a rare cause of subclavian steal syndrome secondary to a dialysis arteriovenous fistula (AVF). A 69-year-old female with end-stage renal disease presented with ataxia and recurrent fainting spells. Angiography revealed normal subclavian arteries bilaterally, a right VA origin occlusion, and an apparent left VA origin occlusion. However, carotid artery angiography demonstrated flow th...

Diabetes is considered a risk factor for arteriovenous fistula failure and increased perioperative complications; but this view not proven patients undergoing brachiobasilic transposition (BBT-AVF). Fifty-one (68.9%) diabetic 23 (31.08%) non-diabetic single-stage BBT-AVF were compared in terms of complications, access maturation patency rates at The Aga Khan University Hospital from between Jan...

Circulatory distress can occur in the long term after the formation of a traumatic arteriovenous fistula (AVF), but cardiac failure rarely occurs in a patient with an AVF in the lower extremity. The present patient underwent surgery to treat a traumatic popliteal AVF 9 years after sustaining the injury. Although the patient was asymptomatic with regard to cardiac circulation, cardiomegaly was n...

BACKGROUND Neointimal hyperplasia is considered to be the major cause of arteriovenous fistula (AVF) failure, resulting in vein wall thickening, stenosis and, ultimately, occlusion. Ultrasound (US) has been shown to be effective for detecting these morphological changes in patients. The aim of this study was to develop an experimental AVF model in the rat that shows typical features of fistula ...

The arteriovenous fistula (AVF) is the preferred access for haemodialysis [1]. However, AVF failure has become more common over the last three decades as more patients are older, and have diabetes or vascular disease. For radiocephalic AVF, a meta-analysis estimated modest primary (63%) and secondary (66%) patencies at 1 year [2]. AVF failures have been attributed to inadequate vessels used for...

Received May 2007 Accepted September 2007 INTRODUCTION Renal arteriovenous fistula (AVF) due to a noniatrogenic penetrating trauma is uncommon. In most reported cases, renal AVF has been one of the complications of interventional urologic procedures.(1) Most cases secondary to percutaneous needle biopsy of the kidney are resolved spontaneously in contrast to those caused by traumas.(2) Angiogra...

At the time of hemodialysis vascular access evaluation, many chronic kidney disease patients already have iatrogenic injury to their veins which impedes the surgical construction of an arteriovenous fistula (AVF). Achieving the important goal of a greater prevalence of arteriovenous fistulae in the US hemodialysis population will require identification of those patients prior to reaching end-st...

Traumatic lumbar artery injuries are quite uncommon, and arteriovenous fistula (AVF) lesions also rare. The clinical symptoms associated with AVF of the often vague non-specific can be masked by due to spinal cord injury. Therefore, missed if performance a contrast-enhanced computed tomography (CECT) scan is absent. In this article, we portrait case post-traumatic along pseudoaneurysm in 40-yea...

BACKGROUND Arteriovenous Fistula (AVF) is the ideal method of vascular access for patients on maintenance hemodialysis (HD). Therefore it is an important part of treatment in HD. There are several observations that indicate the role of inflammation in failure of AVF. The aim of this study was to evaluate the hematologic and inflammatory biomarkers in early AVF failure. METHODS This case-contr...
