    Blood blister-like aneurysms (BBAs) are among the most hazardous cerebrovascular aneurysms to treat; microsurgical treatment of these small, wide-necked, and exceptionally fragile aneurysms place patients at significant risk of morbidity or mortality. We report two cases of ruptured BBAs attempted to be treated for the first time with stent-assisted coil embolization solely and review the current literature on treatment options. Our patients underwent stent-assisted coil embolization of the aneurysms in the acute stage of subarachnoid hemorrhage (SAH). One patient was successfully treated without procedure-related complications. The other patient died after surgical internal carotid artery (ICA) occlusion, carried out after intraoperative rerupture of the aneurysm during the endovascular treatment. In the successful case, 8-month and 19-month follow-up angiograms demonstrated incomplete (90%) occlusion with residual filling of the aneurysm neck, which did not need additional coil embolization. Even though stent-assisted coil embolization of ruptured BBAs in the acute stage appears to be a technically feasible treatment option, the present stent-related endovascular technology has potentially hazardous drawbacks.
