BackgroundLittle is known about the best revascularization procedure for patients with contralateral carotid artery occlusion (CCO). We aim to compare the outcomes of transcarotid artery revascularization (TCAR), carotid endarterectomy (CEA), and transfemoral carotid artery stenting (TFCAS) in patients with CCO.Study DesignPatients in the Vascular Quality Initiative dataset who underwent CEA, TFCAS, or TCAR, and had CCO between September 2016 and April 2020, were included. Multivariable logistic analysis was used to evaluate in-hospital outcomes.ResultsThe final cohort included 1,144 TCARs, 1,182 TFCAS, and 2,527 CEA procedures performed in patients with CCO. Compared with TFCAS, TCAR was associated with a significant reduction in the odds of in-hospital stroke or death (odds ratio [OR] 0.26; 95% CI: 0.12-0.59; p < 0.01). However, no significant difference in stroke was noted (OR 0.71; 95% CI 0.34-1.51; p = 0.38). These results persisted after stratifying with respect to symptomatic status (p values of interaction = 0.92 and 0.74, respectively). There was no significant difference between TCAR and CEA in odds of in-hospital stroke or death on multivariable adjustment (OR 0.57; 95% CI: 0.29-1.10, p = 0.10). The interaction between procedure type and symptomatic status in predicting in-hospital stroke was statistically significant (p = 0.04). In asymptomatic patients, TCAR was associated with a 50% to 60% reduction in the odds of stroke (p = 0.04). Yet, no significant differences were observed in symptomatic patients.ConclusionsTCAR has lower odds of in-hospital stroke or death compared to TFCAS, independent of symptomatic status. Compared to CEA, TCAR seems to be a better option in asymptomatic patients, with lower odds of in-hospital stroke. Yet, no significant difference is observed in symptomatic patients.Published by Elsevier Inc.
