摘要

Abstract Objectives To evaluate the long‐term outcomes of a conservative approach (with proximal aortic replacement with or without hemiarch replacement) versus an aggressive approach (with total aortic arch replacement) in the treatment of acute type A aortic dissection (ATAAD). Methods We performed a pooled analysis of Kaplan–Meier‐derived individual patient data?from studies with follow‐up comparing the aforementioned approaches to treat patients with ATAAD. Results Eighteen studies met our eligibility criteria, comprising 5243 patients with follow‐up (Conservative: 3676 patients; Aggressive: 1567 patients). We observed a statistically significant difference in overall survival favoring the aggressive approach (hazard ratios?HR 0.86, 95 confidence interval CI?0.76–0.98, p?=?.022), but no statistically significant difference in the risk of reoperation (HR 0.89, 95 CI 0.66–1.2, p?=?.439) in the overall follow‐up. Landmark analyses revealed that, in the first 3 months after the procedure, mortality rates were comparable between conservative and aggressive approaches (HR 1.04, 95?CI 0.88–1.24, p?=?.627), but the results beyond 3 months showed improved survival in patients undergoing the aggressive surgical procedure (HR 0.71, 95?CI 0.59–0.85,?p?
