弹簧圈再栓塞或覆膜支架治疗颅内动脉瘤复发

目的报道用弹簧圈再次栓塞或覆膜支架治疗颅内复发动脉瘤的经验。方法291例患者共305枚颅内动脉瘤行可脱卸弹簧圈治疗。随访期间,142例颅内动脉瘤中有41例(28.9%)动脉瘤复发。6个月内有脑血管造影随访的31例共31枚复发动脉瘤纳入本研究,其中20例行可脱卸弹簧圈再栓塞(A组),11例行覆膜支架置入术(B组)。将动脉瘤血管造影结果分为完全闭塞、不完全闭塞;临床评估分级为完全康复,改善,无变化,加重或进展。收集并分析技术成功率,即刻和末次血管造影结果等资料。结果所有复发动脉瘤弹簧圈栓塞和支架置入技术均获得成功。即刻脑血管造影示A组11例(55%)动脉瘤完全闭塞,B组8例(72.7%)完全闭塞;末次脑血管造影示A组10例(50%)动脉瘤完全闭塞,B组11例(100%)完全闭塞,两组间差异有统计学意义(P=0.005)。结论弹簧圈栓塞后动脉瘤复发,可以行弹簧圈再次栓塞术或覆膜支架置入术治疗和闭塞瘤腔。覆膜支架可能比弹簧圈栓塞能更有效地完全闭塞复发动脉瘤。

Endovascular treatment of recurrent intracranial aneurysms with re-coiling or covered stents

Objective To report our experiences in the treatment of recurrent intracranial aneurysms with re-coiling or covered stents.Methods A total of 291 patients with 305 intracranial aneurysms were treated with detachable coils,and 41(28.9%) of 142 patients with aneurysms in the internal carotid artery had a recurrent aneurysm during the follow-up period.For this study,31 recurrent aneurysms in 31 patients who had angiograms within 6 months following retreatment with detachable coils(group A,n = 20) or covered st...
