Stanford B型主动脉夹层腔内修复术的研究进展

Research progress in endovascular aortic repair of Stanford B type aortic dissection

Stanford B型主动脉夹层(TBAD)一直是腔内修复治疗的难点和重点,尤其是对重要脏器分支血管血供的重建。传统方法施行的开胸分支血管转流术或血管旁路搭桥术,虽然可以完成分支血管血供重建,但其手术创伤大,术后病死率及并发症发生率高。胸主动脉腔内修复术(TEVAR)目前已广泛应用于胸腹主动脉疾病的治疗,因其微创、安全、高效、成功率高等特点,很大程度上取代了传统外科手术,成了临床治疗TBAD的首选方法。同时国内外学者积极探索了该技术在分支血管重建中的应用,并初步得到了良好的近期疗效。

Stanford B type aortic dissection(TBAD)has always been the main difficulty and focus of endovascular repair,especially for the restoration of blood supply in important organ branches.The traditional thoracotomy branch vascular bypass or vascular bypass reveals a high incidence of postoperative mortality and complications due to large surgical trauma.Thoracic endovascular aortic repair(TEVAR)has been widely applied in treating thoracic and abdominal aortic diseases owing to its minimal invasion,safety,efficiency,and high success rate.To a considerable extent,TEVAR has largely replaced traditional surgery and has been the preferred clinical treatment for TBAD.This technique to reconstruct branched vessels has been actively explored by scholars and has obtained good short-term efficacy preliminarily.
