A patient with a subarachnoid haemorrhage due to a large right-sided internal carotid artery aneurysm presented unusual problems in management. Direct obliteration of the aneurysm was not possible, while ligation of the internal carotid artery as an alternative form of treatment necessitated the provision of an alternative collateral blood supply to the right cerebral hemisphere, the anterior circle of Willis being deficient. This case illustrates a new surgical technique which has a place in the management of selected cases of cerebral ischaemic disease.
一名因右侧颈内动脉大型动脉瘤导致蛛网膜下腔出血的患者在治疗中出现了不同寻常的问题。直接闭塞动脉瘤无法实现，而结扎颈内动脉作为一种替代治疗方式则需要为右侧大脑半球提供替代的侧支血液供应，因为Willis环前部存在缺陷。本病例说明了一种新的外科技术，该技术在某些脑缺血性疾病病例的治疗中占有一席之地。
