Willis覆膜支架治疗颈内动脉血泡样动脉瘤的疗效分析

目的探讨Willis覆膜支架治疗颈内动脉血泡样动脉瘤(BBA)的安全性和有效性。方法回顾性分析2015年12月至2019年1月采用Willis覆膜支架治疗的15例颈内动脉BBA的临床资料。结果15例共用16枚支架,均成功置入载瘤动脉。术后即刻造影动脉瘤均不显影,1例术中破裂出血,1例围手术期出血,1例围手术期急性支架内血栓形成。12例进行造影随访,13例临床随访;随访时间3~30个月,平均12.1个月;10例动脉瘤完全不显影,载瘤动脉通畅;1例术后3个月原动脉瘤部位局部膨出,1例术后26个月CTA示左侧颈内动脉闭塞,没有神经功能的受损;mRS评分0分11例,1分1例,5分1例。结论Willis覆膜支架治疗颈内动脉BBA是安全有效的,尚需更长时间的随访和较大样本的随机对照研究来证实。

Endovascular treatment of blood blister-like aneurysms of internal carotid artery using Willis covered stent

Objective To explore the safety and efficacy of Willis covered stent in the treatment of blood blister-like aneurysms of the internal carotid artery. Methods The clinical data of 15 patients with blood blister-like aneurysms of the internal carotid artery Who were treated with the Willis covered stents from December, 2015 to January, 2019 were analyzed retrospectively. Results All the 15 patients were successfully implanted with 16 stents. The DSA obtaining immediately afer the placement of the stent showed that the aneurysms were disappeared in all the patients. Intraoperative hemorrhage occurred in 1 patient. Procedure-related complications occurred in two patients, including acute in-stent thrombosis in one patient, and intracranial hemorrhage in one patient. The follow-up time ranged from 3 to 30 months, with an average of 12.1 months. The angiographic follow-ups were performed in 12 patients, of whom the aneurysms were disappeared in 10 patients and mild recurrence in 1, and the left internal carotid artery was occluded in 1. The modified Rankin scale (mRS) score was 0 in 12 patients, 1 in 1 patient, and 5 in 1 patient. Conclusions For treatment of blood blister-like aneurysms of the internal carotid artery, Willis covered stent is safe and effective, but it still needs longer follow-up and randomized controlled clinical trials to confirm
