血管腔内覆膜支架治疗胸降主动脉瘤

Endovascular stent graft treatment of acute or chronic aortic dissection in 36 cases

目的探讨覆膜支架治疗急、慢性胸降主动脉瘤的方法及效果。方法对36例胸降主动脉瘤的临床资料作回顾性分析。结果使用覆膜支架36枚，完全封堵动脉内膜破口，真腔血流恢复正常，近期疗效满意。结论使用覆膜支架腔内隔离术治疗胸降主动脉瘤，符合其病理解剖特点，能很好地封闭内膜破口．具有创伤小、适应证宽、治疗效果确切、康复迅速等优点。

Objective To study the results of endovascular stent graft implantation in treatment of acute or chronic aortic dissection. Methods A retrospective analysis was performed in 36 cases of aortic dissections from 2003 to 2012. Results 36 grafts were successfully implanted on condition that the blood flow of left upper limb was not ＇affected. The inner caks were completely occluded and blood flow of the true lumen resumed satisfactorily. Conclusion Stent graft in treating aortic aneurysm is pathologically and anatomically suitable for the occlusion of the inner leak. The ischemia of upper limb and the steal syndrome can be avoided.
