Postoperative rupture of an artery dissected from a cerebral aneurysm dome following clipping: A rare and fatal complication Open
The adhesion of arteries to aneurysm domes can pose significant technical challenges during surgical clipping. Dissection of these vessels carries a risk of iatrogenic wall damage and subsequent complications. We present the case of a 67-y…
