Arteriovenous fistula (AVF) maturation failure is the primary cause of dialysis vascular access dysfunction. To evaluate whether preoperative vascular functional properties predict postoperative AVF measurements, patients enrolled in the Hemodialysis Fistula Maturation Study underwent up to five preoperative vascular function tests (VFTs): flow-mediated dilation (FMD), nitroglycerin-mediated di...

INTRODUCTION One complication of autogenous arteriovenous fistula (AVF) for haemodialysis is the formation of a venous aneurysm. CLINICAL PICTURE The clinical picture is typically an expanding aneurysm leading to skin atrophy and ulceration with the risk of rupture and infection. Aneurysm also reduces the potential cannulation area. TREATMENT The cases described here used a surgical 'remode...

Life expectancy in patient with established kidney failure is considerably shortened with worsening quality of life. Through the provision of renal replacement therapy, survival and quality of life of advanced renal disease patients can be markedly improved. Haemodialysis and peritoneal dialysis are the treatment modalities in patients with end-stage renal disease. The efficiency of haemodialys...

Background and objectives: The kidneys of chronic kidney disease (CKD) patients do not have enough function and hemodialysis (HD) is a common procedure for their treatment. HD requires vascular access surgery (VAS) and arteriovenous fistula (AVF) is a low-complication method in VAS. However, different rates of AVF failure have been reported worldwide which can cause repeating s...

We report the utility of fluorescent indocyanine green (ICG) during the microsurgical resection of a giant perimedullary cervical arteriovenous fistula (GPMAVF) in a young man with hereditary hemorrhagic telangiectasia. ICG angiography is a useful adjunct for understanding angioarchitecture and drainage patterns in spinal arteriovenous malformation (AVM) surgery. Cervical GPMAVF is a rare spina...

Multifocal capillary malformation (CM) is the cardinal feature of patients with RASA1 mutations. These CMs are 'red flags', signalling the possible association with an arteriovenous malformation (AVM) or an arteriovenous fistula (AVF). We report an 8-year-old boy who presented with > 20 CMs, who was found to have a novel mutation in the RASA1 gene. Radiological screening of children with RASA1 ...

OBJECTIVE To compare the patency rate and complications of arteriovenous fistula (AVF) with synthetic graft in patients with previous history of failed AVF. METHODS This study was carried out at Sina Hospital, Tehran, Iran from April 2002 to July 2003. Patients who had been referred to our center with previous failed attempt for creation of AVF were collected. We again tried to create an AVF ...

Efficacy of percutaneous deep venous arterialization (pDVA) has been reported for patients with no-option chronic limb-threatening ischemia (CLTI). In the countries where a manufactured device dedicated pDVA not reimbursed, using off-the-shelf technique alternatively spread. The techniques arteriovenous fistula (AVF) creation are as follows: AV spear technique, simplified (VAST), and use penetr...

An abnormal communication between an artery and a vein is known as arteriovenous malformation (AVM) or arteriovenous fistula (AVF). The AVM or the AVF might be congenital in origin or even acquired. The arteriovenous communications are usually surgically made in patients undergoing repeated hemodialysis, while suffering from any chronic renal disease. The abnormal arteriovenous communications m...
