Anomalous dual posterior tibial arteries

Abstract

Congenital vascular anomalies present significant diagnostic and therapeutic challenges in the scope of vascular surgery. We present a case of anomalous dual posterior tibial (PT) arteries in a diabetic patient with an infected nonhealing foot wound. The clinical, radiologic, and pathological results are presented. We report on a case of a 45-year-old patient with type 2 diabetes mellitus and an infected nonhealing ulceration on the left heel and midfoot. Given concern for ischemic ulceration, an angiogram was performed revealing anomalous dual PT arteries. This rare variant of PT artery anatomy presents challenges in initial diagnosis and limb salvage.
