E-mail: [email protected] Dear editor–in Chief, Performance of a successful hemodialysis procedure requires a functional vascular access. The preferred type of access is a native fistula because they have the l...

Background: Vascular Access (VA) is an important aspect for blood circulatory in Hemodialysis (HD). Arteriovenous Fistula (AVF) is a suitable procedure to gain VA. Maturation of the AVF is a status of AVF, which can be cannulated for HD. This study aimed to discover the parameters that effectively reduce the duration between VA and start of HD, which symbolizes the maturation time (MT). &nbs...

INTRODUCTION Hemodialysis with arteriovenous fistula (AVF) has been widely accepted treatment modality for patients with chronic renal failure (CRF). Radiocephalic fistulas are considered to be the most desirable for the initial vascular access. The aim of this study is to investigate the surgeon factor on radiocephalic fistula patency rates. METHODS A total of 186 patients with diagnosis of ...

Hemodialysis patients require a vascular access that is, preferably, surgically created by connecting an artery and vein in the arm, i.e. an arteriovenous fistula (AVF). The site for AVF creation is chosen by the surgeon based on preoperative diagnostics, but AVFs are still compromised by flow-associated complications. Previously, it was shown that a computational 1D-model is able to describe p...

The clinical practice guideline for vascular access in haemodialysis recommends the use of arteriovenous fistula (AVF) over a central venous catheter. AVF needs to be created sufficiently in advance of anticipated haemodialysis. However, many incident haemodialysis patients are still being dialyzed with central venous catheter at the time of first haemodialysis. This paper aims at presenting th...

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 ...

BACKGROUND Arterial diameter changes in response to flow. Chronic flow-mediated arterial enlargement may be mediated through metalloproteinase activity in the extracellular matrix of the arterial wall. We examined flow-mediated enlargement in the setting of increasing competitive matrix metalloproteinase (MMP) inhibition and with respect to gelatinase A and B expression and activity. METHODS ...

End-stage renal disease (ESRD) leads to severe illness and death if left untreated. The number of patients requiring renal replacement therapy by haemodialysis is rising rapidly [12]. A well functioning vascular access is a prerequisite for successful haemodialysis treatment. Achieving long-term haemodialysis vascular access is becoming a challenge because of an increase in elderly haemodialysi...

Abstract Background End-stage renal disease (ESRD) has significantly increased in developing countries such as Egypt [1]. There are many sites for arteriovenous fistula (AVF) creation. The most common AVF radio-cephalic (RC-AVF) followed by brachio-cephalic (BC-AVF) [2]. To date, there no significant studies discussing the possible correlation between location and abnormalities right ventricle ...
