Objective: The impact of sex on outcomes of thoracic endovascular aortic repair (TEVAR) represents an area of increased interest over the last decade, and long-term data are lacking. The aim of the present study was to investigate sex-related differences in long-term outcomes after TEVAR using real-world data from the Global Registry for Endovascular Aortic Treatment. Methods: Data were obtained retrospectively after querying the multicenter, sponsored Global Registry for Endovascular Aortic Treatment. Patients treated with TEVAR between December 2010 and January 2021 were selected regardless of the type of thoracic aortic disease. The primary outcome was sex-specific all-cause mortality at 5 years and maximum follow-up. Secondary outcomes were sex-specific all-cause mortality at 30 days and 1 year, and aorta-related mortality, major adverse cardiac events, neurological complications, and device-related complications or reinterventions at 30 days, 1 year, 5 years, and maximum follow-up. Results: A total of 805 patients were analyzed; 535 (66.5%) were males. Females were older (median, 66 years [interquartile range (IQR), 57-75 years] vs 69 years [IQR, 59-78 years], P <.001). Males had more frequently a history of coronary artery bypass grafting and renal insufficiency (8.7% vs 3.7% [P =.010] and 22.4% vs 11.6% [P <.001]). The median follow-up was 3.46 years (IQR, 1.49-4.99 years) for males and 3.18 years (IQR, 1.29-4.86 years) for females. Indications for TEVAR were mostly descending thoracic aortic aneurysms (n = 307 [38.1%]) type B aortic dissections (n = 250 [31.1%]) or others (n = 248 [30.8%]). Freedom from 5-year all-cause mortality was similar for males and females (67% [95% CI, 62.1-72.2] vs 65.9% [95% CI, 58.5-74.2]; P =.847), and there were no differences in secondary outcomes. Multivariable Cox regression showed females to have lower all-cause mortality rates; however, this difference did not reach statistical significance (hazard ratio, 0.97; 95% CI, 0.72-1.30; P =.834). Additional subgroup analyses based on the indication for TEVAR did not identify differences between both sexes for the primary and secondary outcomes except more endoleak type II in females with complicated type B aortic dissection (1.8% vs 12.1%; P =.023). Conclusions: The present analysis suggests that long-term outcomes of TEVAR performed irrespective of the type of aortic disease are similar for males and females. Further studies are needed to clarify existing controversies regarding the impact of sex on outcomes of TEVAR.

Abstract

Objective: The impact of sex on outcomes of thoracic endovascular aortic repair (TEVAR) represents an area of increased interest over the last decade, and long-term data are lacking. The aim of the present study was to investigate sex-related differences in long-term outcomes after TEVAR using real-world data from the Global Registry for Endovascular Aortic Treatment. Methods: Data were obtained retrospectively after querying the multicenter, sponsored Global Registry for Endovascular Aortic Treatment. Patients treated with TEVAR between December 2010 and January 2021 were selected regardless of the type of thoracic aortic disease. The primary outcome was sex-specific all-cause mortality at 5 years and maximum follow-up. Secondary outcomes were sex-specific all-cause mortality at 30 days and 1 year, and aorta-related mortality, major adverse cardiac events, neurological complications, and device-related complications or reinterventions at 30 days, 1 year, 5 years, and maximum follow-up. Results: A total of 805 patients were analyzed; 535 (66.5%) were males. Females were older (median, 66 years [interquartile range (IQR), 57-75 years] vs 69 years [IQR, 59-78 years], P <.001).
