Efficacy of total arch replacement with frozen elephant trunk in patients with acute type A aortic dissection.

ABSTRACT:

Objective

To compare the outcomes of classical elephant trunk (CET) + total arch replacement (TAR) and frozen elephant trunk (FET) + TAR using propensity score matching analysis.

Methods

Between 2012 and 2023, 370 patients who underwent TAR were divided into 2 groups based on their elephant trunk type: the CET group (153 patients; 92 men; mean age, 66 ± 13 years) and FET group (217 patients; 116 men; mean age, 64 ± 12 years). Among these patients, 124 from each group were matched using propensity scores to account for differences in patient characteristics.

Results

Early outcomes, such as mortality and morbidity, were similar between the unmatched and matched cohorts. Circulatory arrest time was significantly shorter in the CET group, even after propensity score match
