Abstract
Fibromuscular dysplasia is an uncommon angiopathy that is principally observed in the renal and carotid arteries. Digital ischemia resulting from fibromuscular dysplasia of the forearm arteries is a rare occurrence. This article describes a case of distal radial and ulnar artery fibromuscular dysplasia presenting as paresthesia, claudication, and finger ulceration. Angiography was diagnostic in visualizing the characteristic "string of beads" appearance. In addition to the typical histological findings, we also observed a previously undescribed pathological finding. Surgical management involved resection of the diseased segment and primary anastomosis.
