True aneurysms of the palmar arch of the hand: a report of two cases.

We report on two cases of true aneurysms of the palmar arch, both of which were post-traumatic. One was due to repetitive blunt trauma and the other to a glass cut wound. Both aneurysms were detected clinically as pulsating masses without functional disorders. The presence of elastic fibres and smooth muscle in the aneurysm wall proved it to be a true aneurysm. Both aneurysms were excised and replaced by a vein graft from the foot.
