The effect of extending proximal landing zone in thoracic endovascular aortic repair on the prognosis of Stanford type B aortic dissection

Abstract

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.
