Willis覆膜支架治疗颈内动脉血泡样动脉瘤的疗效

目的 探讨Willis覆膜支架治疗颈内动脉血泡样动脉瘤（BBA）的可行性与有效性。方法 回顾性分析12例采用Willis覆膜支架治疗的颈内动脉BBA的临床资料。结果 12例均成功接受Willis覆膜支架治疗。10例置入Willis 支架后即刻造影显示动脉瘤不显影，载瘤动脉通畅；2例置入Willis 支架后即刻造影有内漏，再次行球囊扩张处理后复查造影动脉瘤不显影。9例出院时改良Rankin量表（mRS）评分0分；2例住院期间并发交通行脑积水行脑室-腹腔分流术，出院时mRS评分2分；1例因肺部感染死亡。术后3~6个月DSA 随访10例，动脉瘤均无复发；1例电话随访病情稳定。结论 Willis覆膜支架治疗BBA技术可行，临床效果显著。

Willis covered stents for treatment of blood blister-like aneurysms of internal carotid artery (report of 12 cases)

Objective To explore the curative effects of Willis cover stents on blood blister-like aneurysms (BBA) of internal carotid artery (ICA). Method The clinical data of 12 patients with BBA of ICA were analyzed retrospectively. Results Of 12 patients with BBA treated with Willis cover stents, 10 received angiography immediately after stenting, which showed that the aneurysms completely disappeared and parent arteries were free and 2 received angiography immediately after stenting, which showed that the aneurysms had internal leakage, which disappeared after dilation of the balloon with stents. Two patients who developed communicating hydrocephalus received ventriculoperitoneal shunt. One patient died of pulmonary infection. DSA showed that no aneurysms recurred in 10 patients and following-up with telephone showed that the condition was stable in 1 patient 3~6 months after the treatment. Conclusion Treating BBA with Wills cover stent technique is feasible and can bring good clinical outcomes to the patients with BBA of ICA.
