Abstract:
True aneurysms of the digital artery are extremely rare, and only several dozen cases have been reported worldwide. A 29-year-old man presented with a pulsatile, tender nodule in his left index finger. Angiography revealed a 7-mm saccular aneurysm of the proper palmar digital artery with well-developed distal collaterals. Under local anesthesia, the aneurysm was excised following proximal and distal ligation. It was histopathologically confirmed as a true aneurysm. Postoperatively, symptoms resolved without ischemic or neurological complications and without recurrence after 1 year. Thus, simple ligation and excision are effective when collateral circulation is sufficient.
