OBJECTIVE: To evaluate the association between sex and outcomes following TEVAR for intact isolated descending thoracic aortic aneurysms (iiDTAA). SUMMARY BACKGROUND DATA: Data regarding sex-related long-term outcomes after TEVAR for iiDTAA are limited and conflicting results regarding perioperative outcomes have been reported. METHODS: We included all TEVAR for iiDTAA between 2014-2019 in the Vascular Quality Initiative linked to Medicare claims, allowing reliable assessment of long-term outcome data. Primary outcomes included 5-year mortality, reinterventions, and ruptures of the thoracic aorta. Secondarily we assessed perioperative outcomes. RESULTS: We identified 685 patients, of which 54% were females. Females had higher aortic size index (females vs. males: 3.31 [IQR, 2.81-3.85] cm/m2 vs. 2.93 [IQR, 2.42-3.36] cm/m2; P.05). CONCLUSIONS: Our findings suggest that females who undergo TEVAR for iiDTAA have similar 5-year and perioperative outcomes as compared with males.
