True aneurysms of the digital artery: case report.

True aneurysms of the digital arteries are extremely rare; a search of the literature in English yielded only 12 cases. An idiopathic true aneurysm of the radial digital artery of the small finger is described, with its clinical presentation and corresponding arteriogram. Microsurgical repair with an interposition vein graft was performed to re-establish the vascular anatomy. To our knowledge this is the first such reconstruction reported.
