Key result
Total arch replacement for DeBakey type I aortic dissection was associated with a non-significant trend toward higher overall mortality compared to hemiarch replacement (25.7% vs 18.7%, p=0.07).
Why the study?
Does total arch replacement compared to hemiarch replacement improve early mortality and reduce new neurological or malperfusion deficits in patients with DeBakey type I acute aortic dissection?

This registry-based study aims to compare the early clinical outcomes of total arch replacement versus hemiarch replacement in patients with DeBakey type I acute aortic dissection.
Easo et al. (2013) conducted a cohort in DeBakey type I aortic dissection (n=658). Total arch replacement vs. Hemiarch replacement was evaluated on Overall mortality (p=0.07). Total arch replacement for DeBakey type I aortic dissection was associated with a non-significant trend toward higher overall mortality compared to hemiarch replacement (25.7% vs 18.7%, p=0.07).
