Trends in Thoracic Aortic Aneurysm Hospital Admissions, Interventions, and Mortality in England between 1998 and 2020: An Observational Study

To assess trends in thoracic aortic aneurysm (TAA) hospital admissions, interventions, and related mortality (ARM) England, examine the impact of endovascular repair on for years 1998 to 2020. Hospital admission operative approach (thoracic repair, [TEVAR] or open surgical repair) using Episodes Statistics, ARM data from Office National Statistics England standardised 2013 European Standard Population were analysed linear regression Joinpoint analyses. was compared between pre-endovascular era (1998 – 2008) (2009 2019). A rising trend incidence has been observed, mainly due non-ruptured admissions (4.11 per 100 000 1998; 95% confidence interval (CI) 3.71 4.50 12.61 2020; CI 12.00 13.21 r2 = .98; p < .001). Operative interventions increased an increase TEVAR (2.15 000; 1.91 2.41 2020 vs. 0.26 0.16 0.36 2006; .90; Reductions TAA observed males females, irrespective age rupture status. The greatest reduction females aged > 80 with ruptured disease (15.26 deaths 9.50 significant last 23 paralleled by a shift towards declining ARM, sex age. reductions death rates era, particularly disease, affirm positive TAA.
