Preventza O, et al. - Researchers aimed at comparing short-term outcomes, long-term survival and reinterventions in patients requiring surgery after chronic Type I and chronic primary Type III aortic dissections. They analyzed 466 patients who underwent thoraco-abdominal aortic aneurysm repair for chronic Type III (n = 239) and Type I (n = 227) aortic dissections. Open repair for chronic Type I and primary chronic Type III aortic dissections resulted in comparable short- and long-term mortality and reintervention rates. The chronic Type I aortic dissection group displayed more frequent respiratory failure.
