AbstractAneurysms of the ulnar artery are most common secondary to blunt trauma to the hypothenar eminence. The anatomic relationship between the superficial branch of the ulnar artery and the hook of the hamate exposes this segment of the artery to injury. The clinical, roentgenographic, and pathologic features of two patients, one with an acute traumatic episode and one with chronic trauma are presented. True aneurysms developed in both patients that eventuated in digital ischemia. Thrombosis of the aneurysm and adjacent arterial segment seemed to be related to the onset of the ischemic symptoms. Digital artery embolization can complicate the thrombotic episode. Although surgical intervention may correct the ischemic symptoms, prevention via industrial education seems to be the best form of management.
