• Vol 9 • November 2007 Hepatic AVF in a Child with Down Syndrome The normal pressure in the portal vein is low due to the minimal vascular resistance in the hepatic sinusoids. Increased resistance to blood flow can occur at three levels: a) pre-sinusoidal (e.g., portal vein thrombosis), b) sinusoidal (e.g., liver cirrhosis), and c) post-sinusoidal (e.g., BuddChiari syndrome). Portal hypertensi...

The most common treatment for end-stage renal disease (ESRD) patients is the hemodialysis (HD). For this kind of treatment, the functional vascular access that called arteriovenous fistula (AVF) is done by surgery to connect the vein and artery. Stenosis is considered the major cause of dysfunction of AVF. In this study, a noninvasive approach based on asynchronous analysis of bilateral photopl...

introduction: hemodialysis through creation of arteriovenous fistula (avf) is an established surgical procedure for patients with end stage renal disease (esrd). anesthetic methods management for this surgery should deal with different risk factors such as hypertension, ischemic heart disease and diabetes. intravenous regional anesthesia (ivra) or bier block anesthesia as an option for avf crea...

Arteriovenous fistula (AVF) between the external carotid artery and external jugular vein is extremely rare, with only few cases reported in the literature so far. Most of these AVFs have been either iatrogenic or secondary to previous trauma. Herein, we report a 42-year-old woman with congenital AVF between the external carotid artery and external jugular vein, presenting with palpitation and ...

INTRODUCTION An arteriovenous fistula (AVF) for placed for hemodialysis may be burdened by one particular complication-the formation of a venous aneurysm. It has been shown that matrix metalloproteinases (MMPs) and neutrophil gelatinase-associated lipocalin (NGAL) could represent markers of disease in both venous and arterial vessels. MATERIALS AND METHODS This case study reports a rare case ...

A well-functioning vascular access (VA) is a mainstay to perform an efficient hemodialysis (HD) procedure. There are three main types of access: native arteriovenous fistula (AVF), arteriovenous graft, and central venous catheter (CVC). AVF, described by Brescia and Cimino, remains the first choice for chronic HD. It is the best access for longevity and has the lowest association with morbidity...

The aim of this study was to develop a tool for prediction arteriovenous fistula (AVF) outcomes and guide shared decision-making about access appropriateness futility in the context recent Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines. KDOQI guidelines discourage ongoing hemodialysis salvage attempts after two interventions prior successful use or three per year overall. data so...

The autogenous arteriovenous fistula (AVF) is the preferred access for chronic hemodialysis in patients with end-stage kidney disease. Careful examination of the upper extremity is essential for the creation of a successful fistula. The quality of the arterial and venous circulation should be well established prior to surgery. However, there are cases when the superficial venous system of the u...

We report an extremely rare case of pial arteriovenous fistula (AVF) caused by trauma. A 61-year-old man suffered from brain contusion by a traffic accident. He was neurologically normal on admission. However, his headache gradually worsened, and partial seizures occurred thereafter. He presented with general tonic seizure 7 days after the head injury. Magnetic resonance imaging demonstrated th...
