电解可脱弹簧圈栓塞治疗颅内动脉瘤

目的:分析应用电解可脱卸弹簧圈(GDC)栓塞治疗颅内动脉瘤的临床效果。方法:6例因蛛网膜下腔出血或其他神经系统症状的病人。经CT或(和)MR以及DSA检查证实为颅内动脉瘤。其中左侧后交通动脉3例,右侧后交通动脉1例,前交通动脉1例,C2段1例。瘤体直径在5～20mm之间。在神经安定+局麻下行动脉瘤栓塞术。先作载瘤动脉造影,明确动脉瘤的大小、形状、体/颈比以及与载瘤动脉的关系。再将微导管和微导丝塑形为相应的形状后经指引导管送至动脉瘤腔中部,选择合适的GDC进行填塞,直至致密填塞。结果:全部病人均一次性栓塞治疗成功,技术成功率为100%。栓塞后即刻行脑血管造影显示动脉瘤腔填塞满意,填充程度均在95%以上。全部病人均无再次出血和并发症产生。结论:经皮穿刺GDC栓塞术是颅内动脉瘤安全、有效和微创的治疗手段。

Clinical evaluation of the endovascular embolization with guglielmi detachable coils for the treatment of cerebral aneurysm

Objective To report experience of the endovascular embolization with guglielmi detachable coils (GDC) in 6 patients with cerebral aneurysm.Methods Cerebral aneurysm were confirmed in 6 patients by CT,MR and DSA..Among them.4 located in posterior communicating artery, one in anterior communicating artery,and one in C 2 segment.The diameter of aneurysm body was measured in from 5 mm to 20 mm.It was embolized with GDC,and the qualification of coils were selected according to the size,form and rate of body/neck to make the aneurysm embolize densely.Results All patients were successfully embolized.The technique success rate was 100% .The filling degree was above 95% .The clinical situation took a turn for the better apparently and no complications occured.Conclusions Endovascular embolization with GDC for the treatment of cerebral aneurysm is a safe,effective and micro- traumatic means.
