Solitaire AB支架动脉取栓术治疗急性颅内大动脉闭塞的疗效分析

目的探讨SolitaireAB支架动脉取栓术治疗急性颅内大动脉闭塞患者的疗效及安全性。方法回顾性分析2013年3—12月11例急性颅内大动脉闭塞并接受SolitaireAB支架动脉取栓术治疗患者的临床资料。其中单纯大脑中动脉闭塞5例，合并颈内动脉颅内段闭塞1例，单纯基底动脉闭塞4例，椎动脉颅内段延伸至基底动脉近段闭塞1例。分析血管再通效果，术后出血情况，评估院内及3个月后的临床结局。结果11例急性颅内大动脉闭塞患者中10例闭塞血管成功再通，8例达到充分再通标准。4例患者在取栓后责任血管存在明显狭窄，给予球囊扩张术，3例因取栓后仍存在管腔狭窄，将SolitaireAB支架在狭窄处释放后狭窄纠正，残余狭窄率〈40％，遂予电解离断。11例患者均未发生症状性颅内出血。术后3个月，5例功能转归良好，其中2例术后即时疗效明显，1周内症状完全缓解；1例术后3个月仍遗留肢体偏瘫；5例死亡，其中4例家属放弃后续治疗出院。结论SolitaireAB支架动脉取栓术治疗急性颅内大动脉闭塞具有较高的血管再通率，可显著改善3个月后的临床结局。为急性颅内大动脉闭塞患者提供了安全有效的血管内治疗方法。

Analysis of curative effect of arterial embolectomy with Solitaire AB stent in treatment of acute intracranial large artery occlusion

Objective To explore the efficacy and safety of arterial embolectomy with Solitaire AB stent in treatment of acute intracranial large artery occlusion. Methods The clinical data of 11 patients with acute intracranial large artery occlusion receiving arterial embolectomy with Solitaire AB stent from March to December 2013 were analyzed retrospectively. Among them, 5 cases were with simple middle cerebral artery occlusion, 1 case combined with occlusion in the intracranial part of the internal carotid artery,4 cases had simple basilar artery occlusion, and 1 case had occlusion in the intraeranial portion of the vertebral arteries extending to intracranial portion of the basilar artery. Revascularization and postoperative hemorrhage were
