Banding between dialysis puncture sites to treat severe ischemic steal syndrome in low flow autogenous arteriovenous access

Abstract

Dialysis-associated steal syndrome with rest pain and ischemic nonhealing ulcers dictates prompt surgical intervention. Distal revascularization with interval ligation is extensive surgery for frail patients in whom calcified distal arteries make anastomosis difficult. Simple banding is appropriate in high-flow fistulas. In low-flow accesses, further flow reduction by simple banding may result in inadequate dialysis and cause thrombosis. However, banding between puncture sites maintains a pressure gradient between the arterial and venous puncture sites that enables adequate flow with effective hemodialysis that would not be possible with banding at the anastomosis. This new technique is a good solution for maintaining access patency and increasing digital pressure while avoiding complicated surgical revisions in high-risk patients.
