支架型人工血管介入治疗6例降主动脉假性动脉瘤患者

Stent-graft in treatment of patients with aortic pseudoaneurysm

目的探讨支架型人工血管介入治疗降主动脉假性动脉瘤的可行性及疗效。方法2001年9月至2004年9月,用支架型人工血管治疗降主动脉假性动脉瘤患者6例。4例病因为外伤,2例病因不明,3例行急诊手术。6例为男性,年龄(42.2±15.2)岁;瘤体直径(5.0±1.1)cm。结果支架型人工血管均顺利植入。1例有近端内漏,术后30d内无死亡。术后随诊(9.3±10.7)个月。1例于术后4个月死亡,1例于5个月后因再发假性动脉瘤接受再次支架型血管植入术。结论支架型人工血管是治疗主动脉假性动脉瘤的有效方法,但中远期效果还有待进一步观察。

Objective To test the feasibility and safety of stent-graft in treatment of pseudoaneurysm in the descending aorta.Methods From September 2001 to September 2004,6 male patients with aortic pseudoaneurysm were treated with stent-graft implantation.Four of them had traumatic rupture of the aorta,and the another two didn't have definite cause of pseudoaneurysm.The diameter of the pseudoaneurysm was (5.0±1.1) cm.Three patients received emergency stent-graft implantation.Results Stent-graft implantation was successful in all the patients.One patient had endoleak.Operative mortality was zero within 30 days after operation.All patients were followed up for (9.3±10.7)months.The patient with internal leak died four month after stent-graft implantation.One patient received second stent-graft implantation 5 months after first operation because of a newly formed pseudoaneurysm at the proximal end of the stent-graft.Conclusion Although the long-term results are not available yet ,early results of stent-graft in the treatment of aortic pseudoaneurysm are satisfactory.
