Unilateral vs. Bilateral Selective Cerebral Perfusion for Acute Type A Aortic Dissection with Frozen Elephant Trunk: Systematic Review and Meta-Analysis.

ABSTRACT: Background/Objectives: Previous studies failed to demonstrate the best cerebral perfusion option during total aortic arch replacement surgery. We therefore sought to investigate clinical results of patients who received unilateral (u) versus bilateral (b) selective antegrade cerebral perfusion (SACP) during total aortic arch replacement by means of the frozen elephant trunk (FET) technique for acute type A aortic dissections (ATAADs). Methods: A systematic review and meta-analysis was performed by including relevant studies reporting outcomes of patients with ATAADs undergoing total arch replacement with the FET technique using either unilateral or bilateral SACP. Pubmed, ScienceDirect, SciELO, DOAJ, and Cochrane library databases were searched until May 2023. Results:
