Pipeline血流导向装置治疗颅内复杂动脉瘤的效果

Effect of Pipeline embolization device in treatment of intracranial complex aneurysms

目的观察Pipeline血流导向装置(PED)治疗颅内复杂动脉瘤的有效性及安全性。方法回顾性分析接受PED治疗的11例颅内复杂动脉瘤患者的临床资料。结果11例患者共12个动脉瘤,植入12枚PED,其中10例植入1枚PED、1例2枚,3个动脉瘤单纯植入PED、9个植入PED联合弹簧圈栓塞;术后立即造影示动脉瘤内对比剂滞留,PED贴壁良好,完全覆盖瘤颈,载瘤动脉通畅。术后1例发生局部急性脑梗死,经治疗后康复。术后随访6~9个月,中位随访时间7.5个月,患者症状均明显缓解或消失,未发现严重并发症,动脉瘤闭塞率75.00%(6/9)。根据O'Kelly-Marotta(OKM)分级:A级0个动脉瘤,B级1个,C级2个,D级9个。改良Rankin评分(mRS):0分10例,1分1例。结论PED治疗颅内复杂动脉瘤的效果及安全性均较好。

Objective To observe the efficacy and safety of Pipeline embolization device(PED)in treatment of intracranial complex aneurysms.Methods Clinical data of 11 patients with intracranial complex aneurysms treated with PED were retrospectively analyzed.Results Twelve PED were implanted in 11 patients with 12 aneurysms.Ten patients were implanted 1 PED and 1 patient with 2 PED,3 aneurysms were implanted PED alone,9 aneurysms underwent PED combined with coil embolization.Cerebral angiography immediately after operation showed that contrast agent was detained in aneurysm and PED adhered well to the wall,completely covered the neck of aneurysms and the artery with aneurysm was unobstructed.One patient had a local acute cerebral infarction after operation and recovered after treatment.Postoperative follow-up time was 6—9 months,the median follow-up time was 7.5 months.The symptoms significantly relieved or disappeared,no obvious complication occurred,and the occlusion rate of aneurysm was 75.00%(9/12).According to O'kelly-Marotta(OKM)grating,there was no aneurysm in grade A,1 of grade B,2 of grade C and 9 of grade D.The modified Rankin scale(mRS)were 0 score in 10 patients and 1 score in 1 patient.Conclusion Treatment of intracranial complex aneurysms with PED has good effect and safety.
