CI, Confidence interval; LOS, length of stay; NA, not applicable; OR, odds ratio.

^aNo significant differences exist between the two patient cohorts with respect to preoperative comorbidities such as coronary artery disease, congestive heart failure, chronic obstructive pulmonary disease, renal insufficiency (preoperative creatinine ≥1.8 mg/dL), and diabetes mellitus, cerebrovascular, or peripheral arterial occlusive disease.

^bContinuous variables are shown as mean ± standard deviation and mean (range), unless otherwise indicated.

^cDetermined using the Fisher exact or t-test, when appropriate.

^dIncluded carotid-to-subclavian bypass, embolization, arch debranching, elephant trunk, or access vessel procedure.

^eDefined as a change in baseline creatinine of ≥25%.

^fDefined as any decrease in baseline ambulatory ability.
