Computational fluid dynamic evaluation of the side-to-side anastomosis for arteriovenous fistula.
OBJECTIVE The goal of this research was to compare side-to-side (STS) and end-to-side (ETS) anastomoses in a computer model of the arteriovenous fistula with computational fluid dynamic analysis. METHODS A matrix of 17 computer arteriovenous fistula models (SolidWorks, Dassault Systèmes, France) of artery-vein pairs (3-mm-diameter artery + 3-mm-diameter vein and 4-mm-diameter artery +6-mm-dia...
متن کاملLigature versus transvenous endovenorrhaphy for closure of side-to-side arteriovenous fistula created for hemodialysis.
PURPOSE To report a novel technique for arteriovenous fistula (AVF) closure in side-to-side fistulas. MATERIALS AND METHODS One hundred and sixty-two patients with side-to-side AVFs, who were candidates for AVF closure, were randomly divided into two groups: group A (84 patients) who underwent AVF ligature and group B (78 patients) who underwent AVF closure using transvenous endovenorrhaphy t...
متن کاملClinical Analysis of Radiocephalic Fistula Using Side-to-side Anastomosis with Distal Cephalic Vein Ligation
BACKGROUND The surgically created arteriovenous fistula has recently been recommended as the best available angioaccess for hemodialysis. Therefore, in this study, we carried out a clinical analysis on surgical procedures in the ligation and division of a distal vein to achieve similar effects as those of vein end-to-arterial side after side-to-side anastomosis. METHODS We retrospectively rev...
متن کاملThe advantages of end-to-side arteriovenous anastomosis over the other two types of arteriovenous anastomosis in dialysis patients.
The functional duration of vascular access in dialysis patients depends on the emergence of threatening complications. Discussions are constantly being held in an attempt to discover their causality and decrease their emergence. In 260 patients undergoing haemodialysis, we have studied the potential existence of a cause-and-effect relation between the emergence of complications in the vascular ...
متن کاملNumerical investigations of the unsteady blood flow in the end-to-side arteriovenous fistula for hemodialysis.
PURPOSE The aim of this study was to investigate the blood flow in the end-to-side arteriovenous (a-v) fistula, taking into account its pulsating nature and the patient-specific geometry of blood vessels. Computational Fluid Dynamics (CFD) methods were used for this analysis. METHODS DICOM images of the fistula, obtained from the angio-computed tomography, were a source of the data applied to...
