✓Ruptured blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) are potentially dangerous lesions because of the high risk of intraoperative bleeding associated with their wide fragile neck. The authors discuss cases in which BBAs were treated endovascularly during the chronic stage and report a case in which a ruptured BBA of the ICA was successfully treated in the acute phase with stent-assisted coil embolization and a subsequent stent-within-a-stent procedure.
Abbreviations used in this paper:BBA = blood blister–like aneurysm; ICA = internal carotid artery; SAH = subarachnoid hemorrhage.
