A Simplified Technique for Extracorporeal Bypass in Hemodialysis

Abstract

A Simplified Technique for Extracorporeal Bypass in Hemodialysis Seigi Tsuchida A simplified technique was devised for extracorporeal bypass in hemodialysis, which was based on the principle of selective renal angiography described by Edholm and Seldinger.¹ The procedures were described of hemodialysis by using a hemodialvtic shunt consisting of catheters intubated into the artery and vein and an A-V shunt made of silicon rubber tube which could be connected to the inlying catheters for intervals between dialyses. The results of clinical trial with this dialyzing circuit system on four patients with chronic renal insufficiency showed its effectiveness in correcting fluid and electrolyte unbalance, and its simplicity and potential usefulness was confirmed.
