NCT07150559
The study is a multicenter, three-arm, open-label, randomized, parallel-controlled trial, which plans to enroll 306 participants diagnosed with acute type A aortic dissection (ATAAD) from 7 hospitals in China. All patients receive total arch replacement (TAR) combined with frozen elephant trunk (FET) implantation and are randomized to Group 1 (arch-clamping technique under mild hypothermia), Group 2 (arch-clamping technique under moderate hypothermia) and Group 3 (Sun's procedure using bilateral antegrade cerebral perfusion) in the ratio of 1:1:1. After a 1-year follow-up, the validity and safety of the mild hypothermic arch-clamping technique for ATAAD was evaluated via the incidence of major adverse events including death, renal replacement therapy, stroke, and paraplegia, as well as times of circulatory arrest, cardiopulmonary bypass, and mechanical ventilation, and length of ICU stay.
NCT06943716
This retrospective cohort study aims to evaluate the efficacy of a Bilateral Modified Catheter Antegrade Cerebral Perfusion (Modified bACP) technique in acute Type A aortic dissection surgery. Medical records from January 1, 2021, through October 31, 2024, at China Medical University Hospital will be reviewed. The primary outcomes include in-hospital mortality and stroke rate, while secondary outcomes include ICU/hospital stay, mechanical ventilation duration, and other postoperative complications (e.g., acute kidney injury, sepsis, myocardial infarction).
