B型主动脉夹层的腔内治疗及疗效观察

目的 探讨B型主动脉夹层腔内修复术的中期疗效.方法 回顾性分析1998年11月至2009年2月行覆膜支架腔内修复治疗115例B型主动脉夹层的临床资料.男7l例,女44例;年龄32～87岁,平均(56±11)岁.伴发病:高血压105例,糖尿病24例,冠心病14例,下肢动脉硬化11例,慢性肾功能不全7例,另5例有近期外伤史.结果 115例中,113例支架置入成功,释放支架人工血管122枚,破口封堵满意.3例同时行相关杂交手术.围手术期内并发症:下肢动脉栓塞2例,急性脑梗塞致偏瘫2例,移植物感染1例,锁骨下动脉窃血征4例,急性肠缺血1例,肺部感染3例,消化道出血l例,肾功能衰竭2例,A型夹层1例.围手术期死亡5例(4.42%).随访75例,随访率66.4%,随访时间7-83个月,平均随访44.5个月.其中支架近远端内漏9例,5例患者行二次腔内修复术;继发A型主动脉夹层2例,再次行血管置换手术.随访中死亡6例(8%),4例分别死于心肌梗死、脑出血、A型夹层破裂等,2例死因不明.结论 覆膜支架腔内修复术是治疗急慢性B型主动脉夹层的有效方法.

Transluminal therapy for type B thoracic dissection

Objective To investigate the technical details and therapeutic effect in treating StarIdford B aortic dissection by endovaseular aortic repair(EVAR). Methods We retrospectively review 115 type B aortic dissection cases undergoing the procedure of mini-traumatic EVAR from November 1998 to February 2009.There were 71 male patients and 44 female patients with a mean age of55.7 years and follow up period from 7 to 83 months for 75 cases. Results The procedure Was technically successful in 113 cases and 122 stent grafts were placed with hybrid surgery being carried out in 3 cases of carotid artery bypass.Severe perioperative complications included subclavian steal syndrome in 4 eases,pulmonaryinfections in 3 cases.arterial embolism in 2 cases,acute cerebral infarction in 2 cases,kidney tailure in 2 cases.alimentary tract hemorrhage,graft infection,acute intestinal ischemia and type A dissection occurred in one each case respectively.Five cases died perioperatively.Among the 75 cases that were fouowed up,there were 9 eases with type I endoleak and at last 5 cases redid endovaacular repmr.2 cases with secondary type A dissection accepted graft replacement.There were 6 deaths during the follow-up period,4 dying of acute myocardial infarction(2 cases),cerebral hemorrhage(1 case),type A dlssection (1 case)respectively,the causes of other2 deaths were not confirmed. Conclusion EVAR was effective for Standford B aortic dissection as shown by midterm follow up.
