Perioperative and Short-Term Outcomes of Sinus Replacement and Conservative Repair for Aortic Root in Acute Type A Aortic Dissection: A Prospective Cohort Study.

ABSTRACT:

Background

To compare outcomes between sinus replacement (SR) and conservative repair (CR) for dissected roots with normal size.

Methods

From October 2018 to April 2021, a prospective cohort study was carried out. Patients were assigned to two groups (SR group and CR group) according to whether they underwent sinus replacement. Propensity score matching was applied to adjust preoperative variables and Kaplan-Meier method was used for survival analysis.

Results

Three hundred and eighty-seven patients were enrolled. In the whole cohort, 18 patients (4.7%) died postoperatively. The operative mortality of SR group was comparable to CR group (3.2% vs. 6.0%, p = 0.192 before matching; 3.5% vs. 7.0%, p = 0.267 after matching) and the incidence of hemostasis man
