Embolism from the aneurysmal sac is a rare but possible manifestation of intracranial aneurysm; thrombus formation is probably related to the combined action of turbulent flow and a 'stagnant zone'. Three cases are presented: 2 with giant aneurysms (1 internal carotid and 1 sylvian) and 1 with a large aneurysm of the middle cerebral artery. In the latter, surgical treatment was performed, while in the others a conservative therapy was preferred. No ischemic manifestations were observed in the follow-up.
动脉瘤囊栓子形成是颅内动脉瘤一种罕见但可能的表现形式；血栓形成可能与湍流和“停滞区”的共同作用有关。本文报告3例：2例为巨大动脉瘤（1例颈内动脉瘤，1例大脑外侧裂动脉瘤），1例为大脑中动脉大型动脉瘤。对于后者实施了手术治疗，而其他病例则选择保守治疗。随访期间未观察到缺血表现。
