血管内栓塞治疗大脑后动脉瘤

目的探讨应用血管内介入栓塞治疗大脑后动脉瘤的方法和安全性。方法回顾性分析应用血管内栓塞治疗的8例大脑后动脉瘤患者的临床特点、治疗方法及预后。结果①8例患者共有8个动脉瘤，其中P1段动脉瘤1例，P1与P2交界处动脉瘤2例，P2段动脉瘤3例，P3段动脉瘤2例；梭形或夹层动脉瘤6例，囊状动脉瘤2例。②球囊闭塞载瘤动脉1例，弹簧圈动脉瘤内填塞同时阻断载瘤动脉5例，动脉瘤内填塞保留载瘤动脉2例。③术后DSA示动脉瘤均完全消失，6例载瘤动脉阻断的患者术后无缺血症状，所有患者均未出现神经功能缺损和其他介入相关并发症。④术后3—6个月复查DSA，未见动脉瘤复发。临床随访1～12年，所有患者均恢复正常生活。结论血管内介入栓塞大脑后动脉瘤是安全、有效的治疗方法。

Endovascular embolization for posterior cerebral artery aneurysms

Objective To investigate the methods and safety of endovaseular embolization for treatment of posterior cerebral artery aneurysms. Methods Eight patients with posterior cerebral artery aneurysms treated by using endovascular embolization were analyzed retrospectively. The clinical features, method of treatment and prognosis of the patients were summarized. Results ①There were eight patients with 8 aneurysms. Of those, one aneurysm was located at the P1 segment, 2 were at the P1-P2 segment, 3 were at the P2 segment, and 2 were at the P3 segment. There werc 6 patients with fusiform or dissecting aneurysm and 2 with saecular aneurysm. ②One patient was treated by balloon occlusion of parent artery. Five patients were treated by coil packing of the aneurysmal sacs and parent artery occlusion. Two patients were treated by coil packing of the aneurysmal sacs only. ③After the procedure, DSA showed that all the aneurysms disappeared completely. There were no ischemic symptoms in the six patients with parent arteries occlusion after the procedure. No neurological deficits and other intervention-related complications were found in all the patients. ④No recurrence of the aneurysrn was observed under DSA re-examination 3 to 6 months after the procedure. The patients were followed up for 1 to 12 years and all returned to their normal life. Conclusion Endovascular embolization is a safe and effective therapeutic approach for posterior cerebral artery aneurysms.
