Intra-Aneurysmal Rupture of an Atheroma during the Clipping of Large Atherosclerotic Aneurysm of the Middle Cerebral Artery: A Case Report with Video Demonstration

We describe a case of an intra-aneurysmal rupture of a squeezed atheroma observed after permanent clipping of an atherosclerotic large middle cerebral artery aneurysm. After tentative clipping to treat the severe atherosclerotic aneurysm in this patient, we applied supplementary clipping to the atherosclerotic area of the aneurysmal sac. The resulting squeezing of the intra-aneurysmal atheroma caused a leakage into the subadventitial layer of the aneurysmal sac. We also discuss the potential ischemic complications of aneurysmal clipping surgery. We conclude that the surgical techniques used to treat these specific aneurysms require circumspect planning through a review of preoperative images.
