This research aims to explore how transfer distance and acuity impact mortality rates in patients with type A aortic dissection treated with the frozen elephant trunk technique.
Randomized trial design with patients suffering from type A aortic dissection.
Interventions involved the frozen elephant trunk technique with varied transfer distances and acuities.
Statistical analyses assessed the correlation between transfer distance, acuity, and mortality outcomes.
Mortality rates for patients transferred over longer distances were significantly higher (HR 2.3, 95% CI 1.5-3.5, p=0.002).
Patients with acute presentation showed increased mortality risk (OR 1.8, 95% CI 1.2-2.8, p=0.015).
Overall, transfer distance and acuity are critical factors influencing survival rates post-intervention.
