The replacement of thoracic aorta and elimination of proximal intimal tear are the classic methods for the treatment of Stanford type A aortic dissection. However, some patients still have residual tears in the distal aorta after operation and lead to dilation of the false lumen due to continuous perfusion. As negative remodeling of distal aorta is closely related to the long-term prognosis of patients, the exploration of related influencing factors has attracted the attention of scholars recently. We aim to review the definition, pathological mechanism and risk factors of unfavorable remodeling after open surgery.
