In order to achieve a tension free repair, a segment of the left cephalic vein at the incision site was harvested, and the radial artery defect was repaired with interposition vein graft by an end to end anastomosis (Fig. 3).
Histopathology images of the excised radial artery aneurysm with H&E (left) and EVG (right) stains. Sections of the vessel show fibrotic and focally thinned out wall with loss of internal elastic lamina. There is also intimal thickening and atherosclerotic changes.
