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.
目的
报告一例颈内动脉（ICA）症状性大脑动脉瘤病例，该动脉瘤与原始三叉动脉变异（PTAv）相关，采用球囊闭塞试验（BOT）评估缺血耐受性。
病例介绍
一名79岁女性因复视而被诊断为ICA分叉处伴有PTAv的症状性大脑大动脉瘤。通过BOT确认灌注区域和PTAv的缺血耐受性后，我们对PTAv进行选择性栓塞并闭塞ICA供血动脉。术后MRI显示无缺血性病变，复视得到缓解。
结论
经BOT评估后，对PTAv进行选择性栓塞并闭塞ICA供血动脉，在大型动脉瘤的治疗中是有效的。
