A 61-year-old man presented to a clinic with the complaint of 6 weeks of right middle finger pain and swelling. His medical history included type 2 diabetes mellitus, hypertension, peripheral arterial occlusive disease, and chronic kidney disease. The patient received dialysis through an arteriovenous fistula in his right arm. The right middle finger became gangrenous after 8 weeks (image A). Postpresentation arteriogram records indicated steal syndrome causing vascular insufficiency in all right hand digits (image B). The right middle finger autoamputated a few weeks later. Hemodialysis is a common risk factor for ischemia of the upper extremity, and amputation is a common sequelae. 1 Studies have shown that currently the best management of dialysis-associated steal syndrome is distal revascularization with interval ligation, which involves ligating an artery distal to the fistula and subsequently forming a bypass. 2 Owing to the high mortality rates of dialysis patients who require upper extremity amputations, early revascularization efforts are key. 3 (doi:10.7556/jaoa.2018.166) References 1.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
