INTRODUCTION: Thoracic endovascular aortic repair (TEVAR) became the standard of care for treating Type B aortic dissections and descending thoracic aortic aneurysms. We aimed to describe the racial/ethnic differences in TEVAR utilization and outcomes.
METHODS: The National Inpatient Sample was reviewed for all TEVARs performed between 2010 and 2017 for Type B aortic dissection and descending thoracic aortic aneurysm (DTAA). We compared groups stratifying by their racial/ethnicity background in White, Black, Hispanic, and others. Mixed-effects logistic regression was performed to assess the relationship between race/ethnicity and the primary outcome, in-hospital mortality.
RESULTS: A total of 25,260 admissions for TEVAR during 2010-2017 were identified. Of those, 52.74% (n = 13,322) were performed for aneurysm and 47.2% (n = 11,938) were performed for Type B dissection. 68.1% were White, 19.6% were Black, 5.7% Hispanic, and 6.5% were classified as others. White patients were the oldest (median age 71 years; p < .001), with TEVAR being performed electively more often for aortic aneurysm (58.8% vs. 34% vs. 48.3% vs. 48.2%; p < .001). In contrast, TEVAR was more likely urgent or emergent for Type B dissection in Black patients (65.6% vs. 41.1% vs. 51.6% vs. 51.7%; p < .001). Finally, the Black population showed a relative increase in the incidence rate of TEVAR over time. The adjusted multivariable model showed that race/ethnicity was not associated with in-hospital mortality.
CONCLUSION: Although there is a differential distribution of thoracic indication and comorbidities between race/ethnicity in TEVAR, racial disparities do not appear to be associated with in-hospital mortality after adjusting for covariates.
