Treatment of thrombosed thumb artery aneurysm: a report of four cases.

Acute thrombosis of a thumb ulnar digital artery aneurysm is painful and associated with varying degrees of ischemia. Treatment of 4 patients with this condition by resection of thrombosed aneurysm and microsurgical vein graft reconstruction of the involved artery is discussed. Complete relief of symptoms, including healing of ulcerations and reversal of cold intolerance, were achieved. The authors recommend resection of the thrombosed thumb ulnar digital artery aneurysm and re-establishment of arterial flow by an interpositional vein graft.
