腹主动脉瘤腔内修复术单中心治疗经验

目的 评价腔内修复术(endovascular aneurysm repair,EVAR)治疗肾下型腹主动脉瘤(abdominal aortic aneurysm,AAA)的围术期和中远期效果.方法 回顾性分析131例AAA行EVAR的临床资料,评价EVAR治疗AAA的安全性和中远期疗效.结果 手术时间(137±29) min,术中出血(142±20) ml、输血(46±26) ml、ICU恢复时间为(17±4)h.围术期主要并发症包括重度心功能不全8例、心肌梗死2例、肺部并发症5例,内漏4例等；随访中发现内漏15例,Ⅰ型8例,Ⅱ型5例,Ⅲ型和Ⅳ型各1例,死亡2例；Kaplan-Meier生存分析无并发症生存率及再次处理率提示60个月后仍有并发症发生,其中40％是需要再次处理的并发症.结论 EVAR是AAA的安全治疗方法,但需要长期严格随访并及时处理并发症.

Endovascular repair of abdominal aortic aneurysm: a single center experience

Objective To evaluate the perioperative and long-term effects of endovascular aneurysm repair(EVAR) of infrarenal abdominal aortic aneurysm (AAA).Methods Clinical data of 131 AAA cases undergoing EVAR were retrospectively evaluated for the safety and long-term efficacy.Results The operative time was (137 ±29) min,blood loss was (142 ±20) ml,blood transfusion was (46 ± 26) ml,ICU staying time was (17 ± 4) h.Major perioperative complications were severe heart failure in 8 cases,myocardial infarction in 2 cases,pulmonary complications in 5 cases,internal leakage in 4 cases.During the period of up to 60 months there were15 cases of endoleak including 8 cases of type Ⅰ,5 cases of type Ⅱ,1 each case of type Ⅲ and Ⅳ and 2 deaths.By Kaplan-Meier survival analysis there were complications developing after 60 months and up to 40％ of them needing reintervention.Conclusions Endovascular repair is the safe treatment for AAA,but discharged patients need close long-term follow-up.Complications that ensued need intensive management.
