We report a rare case of giant aneurysm of the anterior communicating artery, which was followed up by CT scan after unilateral carotid ligation. A 50-year-old female visited our clinic complaining of headache and visual disturbance. Neurological examination revealed bitemporal hemianopsia and loss of visual acuity. A giant anterior communicating artery aneurysm was found on right carotid angiograms. After ligation of the right common carotid artery, the aneurysm was reduced in size. Three weeks later, however, it ruptured and the patient died two months later. Autopsy showed the ruptured dome of the aneurysm. The wall of the sac lacked elastic fibers. It was considered that after carotid ligation the wall of the dome was pressed directly by the remaining blood flow, and the aneurysmal rupture was caused. We should give care to the aneurysm after carotid ligation.
我们报告一例罕见的前交通动脉巨大动脉瘤病例，该病例在单侧颈动脉结扎后进行了CT扫描随访。一名50岁女性因头痛和视力障碍前来我院就诊。神经学检查发现双颞侧偏盲和视力丧失。右侧颈动脉血管造影显示一个巨大的前交通动脉动脉瘤。在结扎右侧颈总动脉后，动脉瘤尺寸缩小。然而，三周后动脉瘤破裂，患者在两个月后死亡。尸检显示动脉瘤破裂的顶部。囊壁缺乏弹性纤维。据认为，颈动脉结扎后，动脉瘤顶部的壁直接受到剩余血流的压迫，从而导致动脉瘤破裂。我们在颈动脉结扎后应密切关注动脉瘤情况。
