Differences in Mid-Term Outcomes Between Patients Undergoing Thoracic Endovascular Aortic Repair for Aneurysm or Acute Aortic Syndromes: Report From the Global Registry for Endovascular Aortic Treatment

Abstract

A retrospective review of the Global Registry for Endovascular Aortic Treatment between August 2010 and October 2016. Of 575 patients who underwent thoracic endovascular aortic repair (TEVAR) for descending thoracic aortic aneurysm (DTAA) (305) or acute aortic syndrome (AAS) (270), patients with DTAAs were older and had significantly higher comorbidities than patients with AAS. Between 1 month and 1 year after TEVAR, patients with AAS experienced higher all-cause mortality (7.5% vs 5.0%), aorta-related deaths (2.3% vs 0%), and reintervention rates (4.9% vs 3.0%) than those with DTAA. However, between 1 year and 3 years, all-cause mortality was higher for DTAA (11.8%) than for AAS (7.3%). Patients who underwent TEVAR for DTAA or AAS experienced different mortality and reintervention rates during early and mid-term follow-up.
