Abstract:BackgroundAortic arch replacement(TAR) combined with frozen elephant trunk (FET) technique is a high-risk operation after previous cardiovascular surgery. The aim of the study was to review our strategy and outcomes in this cohort.MethodData were reviewed for patients who underwent TAR combined with FET after previous cardiovascular surgery from January 2010 to December 2020. The patients were divided into elective group and non-selective group.Results63 eligible patients were divided into elective(n = 44) and non-elective(n = 19) groups. The interval between two operations was shorter in non-elective group than elective groups (P = 0.001). The indication for reoperation was different in two groups (P = 0.000), however, the type of reoperations has no differences. Cardiopulmonary bypass time was shorter in elective group than non-elective group (P = 0.000). The over-all 30-day mortality rate was 17.5%, and it was higher in non-elective group (P = 0.013). The 24h drainage increased in non-elective group (P = 0.001) as well as re-explore rate for bleeding (P = 0.022). Postoperative hospital stay prolonged in non-elective group (P = 0.002). However, rates of survival without further aortic events were 72.3 ± 7.1% in elective group, 72.9 ± 13.5% in non-elective group at 5 years, respectively (P = 0. 955).ConclusionReduced 30-day mortality and shortened post-operative hospital stay was observed in elective group, however, long-term survival rate without reintervention were not affected.
