Abstract

Objective: To report a case of symptomatic large cerebral aneurysm of the internal carotid artery (ICA), associated with a primitive trigeminal artery variant (PTAv), which was treated with a balloon occlusion test (BOT) to evaluate ischemic tolerance.

Case presentation: A 79-year-old woman was diagnosed with a symptomatic large cerebral aneurysm of the ICA bifurcating the PTAv due to diplopia. After confirming the ischemic tolerance of the perfusion area and PTAv by BOT, we performed ICA parent artery occlusion with selective embolization of the PTAv. Postoperative MRI showed no ischemic lesion and the diplopia was resolved.

Conclusion: ICA parent artery occlusion with PTAv selective embolization after evaluation by BOT is useful in the treatment of large aneurysms.

有症状的大颈内动脉瘤伴原始三叉动脉变异的母动脉闭塞1例。

目的:报告1例伴有原始三叉动脉变异(PTAv)的症状性颅内动脉瘤(ICA)，采用球囊闭塞试验(BOT)评估缺血耐受性。病例介绍:一名79岁的女性被诊断为有症状的大脑动脉瘤的前卡分叉的PTAv由于复视。经BOT确认灌注区和PTAv的缺血耐受性后，我们行ICA母动脉闭塞术，选择性栓塞PTAv。术后MRI未见缺血性病变，复视消除。结论:经BOT评估后，ICA母动脉闭塞加PTAv选择性栓塞是治疗大动脉瘤的有效方法。
