【摘要】 目的:评估三分支支架血管重建主动脉弓的中远期效果。方法:回顾性分析2008年
6月-2010年6月78例接受三分支支架血管重建主动脉弓手术治疗的急性A型主动脉夹层患者的病历资料,术前均经计算机断层摄影血管造影(CTA)检查确诊为急性A型主动脉夹层。结果:手术死亡
3例(3.8%),治愈出院75例(96.2%)。术后严格随访,随访期间死亡3例(术后1~2年),其中1例猝死,1例心衰,1例死因不明。随访病例CTA检查结果示三分支支架血管均通畅,术后3个月、1年、2年、5年,胸主动脉夹层愈合率分别达80.0%、82.7%、86.1%、85.3%,生活质量良好。结论:三分支支架血管的应用可简化主动脉弓修复手术,降低死亡率,中远期疗效满意。

【Abstract】 Objective:To evaluate the mid and long-term effect of triple-branched stent graft on aortic arch reconstruction.Method:Retrospective analysis of 78 patients with acute type A aortic dissection from June 2008 to June 2010 was performed on the treatment of aortic arch surgery with the reconstruction of the blood vessel with a branch of triple-branched stent graft,preoperative computed tomography angiography(CTA) examination confirmed the diagnosis of acute type A aortic dissection.Result:3 cases(3.8%)died of operation, cured and discharged in 75 cases(96.2%).The patients were followed up strictly,and 3 patients died during the follow-up period (1-2 years after operation).Among them,there were sudden death in 1 case,heart failure in 1 case,and 1 case of unknown cause of death.Follow up CTA examination showed that the triple-branched stent graft of the stent were unobstructed,and after 3 months,1 year,2 years and 5 years,the healing rate of thoracic aortic dissection was up to 80.0%,82.7%,86.1% and 85.3%,respectively.Conclusion:The application of the triple-branched stent graft can simplify the repair of aortic arch, reduce the mortality rate, and the mid and long-term effect is satisfactory.

急性A型主动脉夹层是心血管外科中一种病情凶险、致死率极高的危重疾病[1],存活过急性期的患者不足25%[2]。外科手术是目前最有效的治疗方法[3],其目的是去除原发破口并避免严重并发症,以保障患者生命安全作为第一目标[4-5]。大部分A型主动脉夹层患者的原发破口位于升主动脉,因此升主动脉人造血管置换被认为是治疗A型主动脉夹层的经典手术方式[6-7]。但是20%~25%的A型主动脉夹层破口处于主动脉弓或远端主动脉弓,单纯升主动脉置换无法满足去除破口的需求[8]。并且单纯升主动脉人造血管置换术后主动脉弓及其远端主动脉仍存有假腔,研究表明这些残存假腔的扩张及破裂与术后远期疗效密切相关[9],其存在会严重影响预后,对患者造成巨大的威胁。……
