目的探讨腔内治疗主动脉夹层动脉瘤的方法和疗效。方法42例主动脉夹层动脉瘤患者均以带膜支架型人工血管行腔内隔绝术,4例先行右颈总动脉-左颈总动脉人工血管旁路术,再行腔内隔绝术。结果42例手术成功,无1例患者死亡,无术后截瘫,随访假腔血栓形成。结论腔内治疗主动脉夹层动脉瘤是安全、有效的方法,具有创伤小、并发症少的优点。 Objective To explore the method and effect of endovascular treatment of aortic dissection aneurysm. Methods 42 patients with aortic dissecting aneurysm were treated with endovascular stent - graft exclusion. Four patients underwent first right common carotid artery - left common carotid artery bypass and then endovascular exclusion. Results 42 cases were successful in operation, none of them died, no postoperative paraplegia, follow-up false lumen thrombosis. Conclusion Endovascular treatment of aortic dissection aneurysm is a safe and effective method, with the advantages of less trauma and fewer complications.
