Analysis of the factors affecting the results of arteriovenous fistula surgery

Abstract

Arteriovenous fistulas (AVF) derived from autologous blood vessels are the most common vascular access points used for chronic dialysis in Japan. Although some cases in which AVF creation was unsuccessful have been reported, no large‒scale randomized controlled trials of this approach have been performed in Japan, and no detailed analysis of the factors affecting the initial patency of AVF has been performed. We retrospectively analyzed a group of patients who underwent AVF surgery, and analyzed the factors affecting initial AVF patency. Of the 119 patients studied, 15 had shunt occlusion (12.6％), and a history of deep vein thrombosis was the only factor that was found to significantly affect patency. It is suggested that the presence or absence of thrombotic factors may affect the initial patency rate of AVF more than factors such as sex, age, and a history of diabetes.
