Standford B型主动脉夹层的腔内治疗

A Retrospective Analysis of Endovascular Therapy in Standford B Aortic Dissection

目的:探讨Standford B型主动脉夹层的临床特征和腔内治疗经验。方法:回顾分析2006年10月-2008年3月间收治的117例Standford B型主动脉夹层的临床资料。结果:胸背部疼痛通常为其首发症状;继发性内膜破口多见于内脏动脉开口处。围手术期死亡多与夹层破裂、逆向撕裂引起的脑卒中和心包填塞有关。结论:腔内修复术治疗Standford B型主动脉夹层是安全有效的,对近端锚定区的扩展、继发破口的处理等仍需大样本的长期观察。

Objective：To introduce the endovascular experience by reviewing clinical characteristics of 117 cases of Standford B aortic dissection. Methods： We concluded dpathophysiologic changes of Standford B aortic dissection through harvesting clinical information of aortic dissection from Oct 2006 to Mar 2008 in our center, analyzing histories, images（CTA, DSA） and treat ment. Results： Pain of chest and back was usually the primary symptom and second intima tear often appeared in the viscera ostium. Death during perioperative period was related to rupture of dissection or stroke and cardiac tamponade led by retrograde tear. Conclusion：It is safe and effective that Standford B aortic dissection is repaired by endovascular therapy, while a large amount follow-up is needed to evaluate elongation of proximal anchorage and management of second intima tear.
