大脑中动脉瘤的血管内栓塞及预后

目的探讨血管内栓塞治疗大脑中动脉瘤的有效性及安全性。方法回顾性分析南京军区南京总医院神经外科自2007年3月至2015年5月采用血管内栓塞治疗的大脑中动脉瘤患者170例共173个动脉瘤的临床资料,包括120个(69.4%)破裂动脉瘤和53个(30.6%)未破裂动脉瘤。比较两组患者的并发症发生率及预后。结果 (1)170例经过术前评估可以行血管内栓塞的患者均成功完成介入手术,无一例患者死亡。(2)18例(10.6%)患者出现术中及术后并发症,其中未破裂动脉瘤组4例(7.5%,4/53),破裂动脉瘤组14例(11.7%,14/120),两组患者并发症发生率的差异无统计学意义(P0.05)。(3)对101例患者进行了影像学随访,随访时间为3~48个月,未出现新发神经系统症状以及动脉瘤再破裂出血。未破裂动脉瘤组1例复发,破裂动脉瘤组4例复发。结论血管内栓塞治疗大脑中动脉瘤是安全、有效、可行的技术。

Endovascular embolization and prognosis of middle cerebral artery aneurysms

Objective To investigate the effectiveness and safety of endovascular embolization for the treatment of middle cerebral artery aneurysms. Methods From March 2007 to May 2015,the clinical data of 170 patients with 173 middle cerebral artery aneurysms treated with endovascular embolization at the Department of Neurosurgery,Nanjing Jinling Hospital were analyzed retrospectively,including 120 (69.4%)ruptured aneurysms and 53 (30. 6%)unruptured aneurysms. The incidence of complications and prognosis were compared between the 2 groups. Results (1)A total of 170 patients who could perform endovascular embolization after preoperative evaluation successfully completed the interventional procedure. None of the patients died. (2)18 patients (10. 6%)had intraoperative and postoperative complications,including 4 (7. 5%,4/53)in the unruptured aneurysm group and 14 (11. 7%,14/120)in the ruptured aneurysm group. There was no significant difference in the incidence of complications between the two groups. (3)101 patients were followed up for 3-48 months. No new nervous system symptoms and reruptured aneurysm were observed. One patient had recurrence in the unruptured aneurysm group and 4 had recurrence in the ruptured aneurysm group. Conclusion Endovascular treatment of middle cerebral artery aneurysms is a safe,effective,and feasible technique.
