A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital ar...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

An 82-year-old man presented with typical signs and symptoms of an arteriovenous fistula (AVF) associated with an aortoiliac aneurysm, such as a pulsatile abdominal mass, continuous bruit, thrill, and high output heart failure. Multidetector row computed tomography (MDCT) confirmed the presence of an AVF between the right common iliac artery aneurysm and vein. We subjected the patient to surgic...

The main options for vascular access in hemodialysis patients are arteriovenous fistulas (AVFs), arteriovenous grafts, and tunneled cuffed central venous catheters. AVFs have the lowest complication rate and require the fewest interventions and lowest cost to maintain. There has been a dramatic national increase in prevalent AVFs among patients with ESRD in the United States driven, in part, by...

This study describes an alternative arteriovenous fistula (AVF) model in the rat in which the animals develop significant neointimal hyperplasia (NIH) not only at the distal anastomotic site, but also throughout the fistula body. This aortocaval fistula was established by anastomosing the distal end of the renal vein to the abdominal aorta after unilateral nephrectomy. The increased hemodynamic...

The rate of arteriovenous fistula (AVF) placement continues to rise and AVF failure is a major complication. The main cause of AVF failure is stenosis leading to thrombosis. Although the detection of early stenosis with preemptive correction prior to thrombosis seems to be a plausible option to prevent access failure, there is much debate, on the basis of studies of surveillance with arterioven...

BACKGROUND Although the proximal radial artery has been reported as an alternative inflow to prevent steal syndrome, brachiobasilic fistula has been reported to be associated with steal syndrome in 10-20% of cases. We aimed to compare proximal radiobasilic arteriovenous fistula (AVF) with brachiobasilic AVFs on the upper arm in terms of steal syndrome and outcomes. MATERIAL AND METHODS We use...

Intracranial pial arteriovenous fistula (AVF) is a rare cerebrovascular malformation, which has a single or multiple arterial connections to a single venous channel without intervening nidus, and is different from arteriovenous malformation (AVM). We report on a case of a surgically treated pial AVF. A 15-year-old girl with an altered mental state was brought to our hospital. Computed tomograph...

In patients unsuitable for radiocephalic fistula creation, the next option is brachiocephalic fistula. In such patients, we exploited the venous interconnections in the cubital fossa for median cubital vein-Brachiocephalic arteriovenous fistula (AVF) creation. In this article, we describe our experience in the creation of such technical variant of the brachiocephalic fistula AVF, its success an...

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...
