Introduction:
Due to their exclusion from most clinical trials, outcomes of carotid revascularization via a carotid endarterectomy (CEA) or carotid artery stenting (CAS) among octogenarians are not well studied. Herein, we present analysis of thirty-day stroke and mortality of patients aged ≥ 80 using real-world data from a national surgical quality registry.
Methods:
The National Surgical Quality Improvement Program (NSQIP) targeted dataset for CEA and CAS was queried for patients aged ≥ 80 undergoing CEA and CAS between 2012-2018.
Results:
A total of 94 and 2,656 patients aged ≥ 80 with symptomatic carotid stenosis undergoing CAS and CEA (respectively) were identified. Patients in the CAS group were more likely to be over 90 (p=0.006). Patients in the CAS group were more likely to have high-risk anatomy (p<0.001) and more likely to be on aspirin preoperatively (p=0.02) but less likely to have higher ASA (p<0.001). Most patients in the group presented with an ipsilateral stroke (CAS: 43.6% and CEA: 41.7%). The rate of thirty-day composite outcome (stroke or death) was found to be 5.3% in the CAS group and 4.5% in the CEA group (p=0.714) (stroke: 2.1% for CAS and 3.2% for CEA; death: 4.3% for CAS and 1.7% for CEA). Upon multivariable analysis, procedure type (CAS vs CEA) was not found to be associated with the composite-outcome (OR 1.1, 95%CI 0.43-2.82,p=0.836). Symptom presentation other than ipsilateral stroke was found to be associated with significantly decreased odds of 30-day composite outcome (amaurosis-fugax/transient monocular blindness: OR 0.42,95%CI 0.21-0.86, p=0.02; TIA: OR 0.62, 95%CI 0.42-0.93,p=0.02), while higher age was found to be associated with significantly increased odds (OR 1.512, 95%CI 1.01-2.24, p=0.02).
Conclusion:
Real world analysis from a surgical quality registry show that both CAS and CEA are associated with optimal 30-day outcomes among octogenarians with symptomatic carotid stenosis.
