Intraoperative rupture of blood blister-like aneurysm: a case report and review of literature

Abstract

Blood blister-like aneurysms (BBLAs) are aneurysms from the non-branching sites of the internal carotid artery (ICA). Though rare lesions, they pose a high risk of intraoperative aneurysmal rupture. Definite treatment of these types of aneurysms has been debatable, but surgical approach is the ultimate rescue treatment. Microsuture of the intraoperative ruptured BBLA has been reported scarcely in literature, but no review of these cases has ever been reported. We here present our experience of a case of BBLA intraoperative rupture requiring microsuture of the ICA and conduct meticulous review of all similar cases.
