ABSTRACT
OBJECTIVE:
Carotid artery stenting (CAS) is frequently used for patients at high risk for carotid endarterectomy. However, there are limited data comparing transradial or transbrachial (tr/tbCAS) access with more established CAS approaches. Therefore, we examined the effect of a tr/tbCAS approach versus a transfemoral (tfCAS) or transcarotid (TCAR) approach on outcomes after CAS.METHODS:
We identified all patients undergoing CAS in the Vascular Quality Initiative registry from January 2016 to December 2021. We compared outcomes across 13 propensity score-matched cohorts of patients who underwent tr/tbCAS versus tfCAS or tr/tbCAS versus TCAR. As a secondary analysis, we assessed outcomes stratified by carotid symptom status. Our primary outcome was a composite end point of in-hospital stroke/death.RESULTS:
Among 40,835 CAS patients, 962 (2.4%) underwent tr/tbCAS, 18,840 (46%) underwent tfCAS, and 21,033 (52%) underwent TCAR. Among matched patients who underwent tr/tbCAS versus tfCAS, there was no significant difference in the risk of stroke/death (4.1% vs 2.9%; relative risk [RR] 1.4; 95% confidence interval [CI], 0.95-2.1), but tr/tbCAS was associated with a higher risk of death (2.4% vs 1.3%; RR, 1.8; 95% CI, 1.1-3.1). In the symptomatic subgroup, tr/tbCAS was associated with a higher risk of stroke/death (6.1% vs 3.9%; RR, 1.6; 95% CI, 1.0-2.4) and death (3.6% vs 1.7%; RR, 2.1; 95% CI, 1.2-3.7), but there were no differences in asymptomatic patients. After adjustment for mRS in patients with preoperative stroke, there were no significant differences in stroke/death (RR, 1.1; 95% CI, 0.66-1.9) or death (RR, 1.6; 95% CI, 0.81-3.3) between groups. In matched patients who underwent tr/tbCAS versus TCAR, tr/tbCAS was associated with a higher risk of stroke/death (4.2% vs 2.3%; RR, 1.8; 95% CI, 1.2-2.7) and death (2.4% vs 0.5%; RR, 4.8; 95% CI, 2.4-9.5). In the symptomatic subgroup, tr/tbCAS remained associated with a higher risk of stroke/death (6.2% vs 2.4%; RR, 2.6; 95% CI, 1.6-4.2) and death (3.7% vs 0.7%; RR, 5.6; 95% CI, 2.6-12), but there were no differences in asymptomatic patients. After adjustment for Modified Rankin Scale in patients with preoperative stroke, there were no significant differences in stroke/death (RR, 1.4; 95% CI, 0.79-2.6) or death (RR, 2.3; 95% CI, 0.95-5.7) between groups.CONCLUSIONS:
Compared with tfCAS or TCAR, tr/tbCAS was associated with a higher risk of in-hospital stroke/death in symptomatic patients, which was driven primarily by a higher risk of death. These inferior outcomes were partly attributable to more severe preoperative neurologic disability in tr/tbCAS patients. In contrast, there were no differences in outcomes in asymptomatic patients. Overall, our findings highlight the importance of guideline-directed patient selection in tr/tbCAS.Palavras-chave
