Two patients with unusually large dorsal internal carotid artery aneurysms manifesting as subarachnoid hemorrhage are described. Surgery in both cases resulted in intraoperative rupture of the sac. The outcome was poor in the first patient and excellent in the second. The importance of wide exposure of the proximal and distal vasculature to the aneurysm, subpial dissection of the frontal and temporal lobes not to injure the fragile aneurysmal dome, and parallel clipping was emphasized for this rare type of aneurysm.
本文描述了两名表现为蛛网膜下腔出血的颈内动脉海绵窦段巨大动脉瘤患者。两例手术均导致瘤囊术中破裂。第一例患者预后较差，第二例患者预后良好。对于这种罕见类型的动脉瘤，强调广泛暴露动脉瘤近端和远端血管、在额叶和颞叶进行软膜下解剖以避免损伤脆弱的动脉瘤瘤顶以及平行夹闭的重要性。
