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