OBJECTIVE
A 63-year-old woman presented with diplopia resulting from abducens paralysis. Examination revealed a giant cavernous aneurysm supplied by the internal carotid artery (ICA) and primitive trigeminal artery (PTA) via the vertebrobasilar system.
METHODS
After evaluation of balloon test occlusion (BTO) at the distal side of the PTA origin, the aneurysm was treated with PTA obliteration through the suboccipital route in the lateral position followed by cervical carotid ligation with superficial temporal artery-to-middle cerebral artery anastomosis in the supine position.
RESULTS
The aneurysm showed marked shrinkage after the surgery.
CONCLUSION
PTA obliteration through the retrosigmoid opening is a therapeutic surgical option in a patient with a cavernous aneurysm supplied by the PTA.
目的
一位 63 岁女性因外展神经麻痹出现复视。检查发现一个巨大的海绵状动脉瘤，由颈内动脉（ICA）和原始三叉动脉（PTA）通过椎基底动脉系统供应。
方法
在 PTA 起源的远端进行球囊试验闭塞（BTO）评估后，通过侧卧位下的枕下入路闭塞动脉瘤，然后在仰卧位行颈总动脉结扎和颞浅动脉-大脑中动脉吻合术。
结果
手术后动脉瘤明显缩小。
结论
通过乙状窦后入路闭塞 PTA 是 PTA 供应的海绵状动脉瘤的一种治疗性手术选择。
