A 67-year-old female was admitted to our hospital because of unconsciousness after severe headache on April 7, 1986. On admission, the patient was semicomatose with anisocoria and absence of light reflex. Computed tomography showed subarachnoidal hemorrhage with intraventricular clots. Right carotid angiogram revealed that the left anterior cerebral artery was filled from the right side through the anterior communicating artery and a saccular aneurysm in anterior communicating artery. On left-side carotid angiogram, neither the left internal carotid artery nor the intracranial arteries were visualized. She died on the 15th hospital day. Complete absence of the left internal carotid artery and hypoplasia of the left A1 portion were verified at autopsy. Sixteen cases of agenesis of the unilateral internal carotid artery have been associated with cerebral aneurysms in the literature. Absence of internal carotid artery was discussed in relation to aneurysm formation.
一名67岁女性于1986年4月7日因剧烈头痛后昏迷入院。入院时，患者呈半昏迷状态，双侧瞳孔不等大且对光反射消失。计算机断层扫描显示蛛网膜下腔出血伴脑室内血凝块。右侧颈动脉血管造影显示，左大脑前动脉通过前交通动脉从右侧供血，且前交通动脉有一个囊状动脉瘤。左侧颈动脉血管造影显示，左侧颈内动脉及颅内动脉均未显影。患者于住院第15天死亡。尸检证实左侧颈内动脉完全缺如，左侧A1段发育不全。文献中已有16例单侧颈内动脉缺如与脑动脉瘤相关的报道。本文讨论了颈内动脉缺如与动脉瘤形成的关系。
