All patients with ruptured aneurysms admitted to neurosurgical departments in Denmark after April, 1978, are the subjects in the prospective study that includes neuropsychological examinations. Data from 48 patients with aneurysms of the anterior communicating artery have been analyzed. Trapping of the aneurysm was done in 11 patients and resulted in an amnesic syndrome in 9. Thirty-seven patients were operated upon by ligation of the neck of the aneurysm or similar procedures, resulting in 6 cases of amnesia. Trapping invariably disrupts blood supply through newly described dorsal perforating branches from the anterior communicating artery. These perforating branches may supply areas of vital importance to memory function.
1978年4月以后入住丹麦神经外科的所有动脉瘤破裂患者均为这项包括神经心理学检查的前瞻性研究的对象。对48例前交通动脉瘤患者的数据进行了分析。11例患者采用动脉瘤夹闭术，其中9例出现遗忘综合征。37例患者通过结扎动脉瘤颈部或类似手术进行治疗，导致6例失忆。夹闭术总是会中断通过新发现的前交通动脉背侧穿支的血液供应。这些穿支可能供应对记忆功能至关重要的区域。
