With the continuous development of endovascular surgery, thoracic endovascular aortic repair (TEVAR) has gradually replaced traditional open surgery and has become the preferred treatment strategy for Stanford type B aortic dissection. However, the disadvantage of the short proximal landing zone greatly limited the indication of TEVAR surgery and affected the prognosis. In recent years, many strategies such as hybrid surgery, in vitro fenestrated and branched aortic endo-graft, chimney technique, in-situ fenestration technique, etc., have been developed, which greatly broadens the TEVAR indication and improved the prognosis.
随着腔内血管外科的不断发展，胸主动脉夹层腔内修复术(TEVAR)已经逐渐取代传统开放手术，成为Stanford B型主动脉夹层的首选治疗策略。然而，近端锚定区的不足在限制TEVAR适应证的同时，对预后也有不利影响。近年来，随着杂交手术、体外开窗、带分支主动脉支架、烟囱技术、原位开窗技术等临床新技术的应用，拓展近端锚定区的策略越来越丰富，拓宽了TEVAR的适应证，改善了TEVAR的预后。.
