Carotid-Axillary Bypass as an Alternative to Carotid-Subclavian Bypass Following Coverage of Left Subclavian Artery During Thoracic Endovascular Aortic Repairs

Abstract

used to calculate adjusted 30-day mortality and long-term survival, respectively.Results: A total of 1832 patients underwent AAA repair from 2005 to 2015. Baseline characteristics were similar across MDI quintiles with the exception of coronary disease and peripheral vascular disease (Table ). The 30-day outcomes were similar across MDI quintiles (Table ). Univariable regression revealed no difference in 30-day mortality across MDI quintiles (P ¼ NS) but did find age >70 years (odds ratio [OR], 2.17; 95% confidence interval [CI]. 1.37-3.43; P ¼ .001), female sex (OR, 1.58; 95% CI, 1.01-2.48; P ¼ .044), history of stroke (OR, 2.28; 95% CI, 1.31-3.96; P ¼ .003), and endovascular approach (EVAR) (OR, 0.20; 95% CI, 0.10-0.42; P < .001) to significantly impact 30-day mortality. Multivariable analysis revealed age >70 years (OR, 2.41; 95% CI, 1.51-3.84; P < .001), history of stroke (OR, 2.21; 95% CI, 1.27-3.94; P ¼ .006), and EVAR (OR, 0.18; 95% CI, 0.09-0.38; P < .001), but not MDI (P ¼ NS) or sex (P ¼ NS) to be associated with increased 30-day mortality. There was no effect of MDI quintile on long term survival on univariable analysis, and after adjusting after age, sex, chronic obstructive pulmonary disease status, and EVAR (Figure ).Conclusions: SES does not appear to affect short nor long term mortality after AAA repair in a publicly funded health care system.
