Abstract No. 579 Retrospective Evaluation of Carotid Artery Calcium Scores on Contrast-Enhanced CT Angiography and Its Association with Restenosis and Reintervention After TCAR or TFCAS

Carotid endarterectomy (CEA), trans-carotid artery revascularization (TCAR), and transfemoral carotid artery stenting (TFCAS) are established interventions for mitigating stroke risk in patients with high-grade stenosis. Despite their efficacy, adverse outcomes such as stroke, death, and lesion restenosis remain concerns. Younger age, prior endarterectomy, history of neck radiation, and high calcium burden have been identified as predictors of restenosis. This study aims to establish a reliable method for quantifying carotid artery calcium burden on contrast-enhanced computed tomography angiograms (CECTAs) and analyze the relationship between calcium burden or scoring on CECTA and the incidence of high-grade restenosis or the need for reintervention.
