Bilateral radial artery pseudoaneurysms associated with bilateral ulnar artery atresia: a case report.

Abstract

Pseudoaneurysms of the radial artery are uncommon and most often localized in an area of penetrating vascular trauma or iatrogenic injury. Hypoplasia of the ulnar artery is even more rare. We report a case of bilateral radial artery pseudoaneurysms associated with complete absence of any ulnar contribution to the vascularity of the hand. A patient presented with bilateral tender masses adjacent to the anatomic snuff boxes that interfered with hand function. After confirming that these masses were bilateral radial artery pseudoaneurysms, resection of the pseudoaneurysms and microscopic reconstruction of the arterial segments preserved vascular integrity of the hands and provided relief of the patient's pain.
