Retrograde type A aortic dissection after thoracic endovascular aortic repair: Incidence, Time trends and Risk factors.

To review the incidence of retrograde type A aortic dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) of patients with type B aortic dissection (TBAD), and to investigate its time trends and underlying risk factors. The incidence rate of RTAD after TEVAR for TBAD was gathered as a cumulative pool for each year in meta-analysis. Linear regression was used to establish the temporal trend of RTAD incidence. Annual decrease rate was calculated for the fulltime frame. Sixty-six articles were included in this study, which represented 11149 patients enrolled since 1994, and the research published between 2000 and 2019. The overall pooled rate of RTAD incidence is 2.20% (95% CI 0.0162 to 0.0284; p
