Early outcomes of hybrid type II arch repair versus total arch replacement with frozen elephant trunk in acute DeBakey type I aortic dissection: a propensity score-matched analysis.

Objectives: The aim was to evaluate the short-term outcomes of hybrid type II arch repair (HAR) and total arch replacement with frozen elephant trunk (TAR with FET) for acute DeBakey type I aortic dissection patients.

Methods: From January 2017 to June 2019, the clinical data of acute DeBakey type I aortic dissection patients in a single centre were retrospectively reviewed; there were 92 cases of HAR and 268 cases of TAR with FET, with 56 pairs by propensity score matching.

Results: After matching, the composite end points including 30-day mortality, stroke, paraplegia, renal failure, hepatic failure, reintubation or tracheotomy and low cardiac output syndrome were comparable (21.
