Abstract

Objective: The objective of this study was to determine the effect of presenting symptom types on 30-day periprocedural outcomes of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in contemporary vascular practice. Methods: Retrospective review was undertaken of the Society for Vascular Surgery Vascular Registry database subjects who underwent CEA or CAS from 2004 to 2011. Patients were grouped by discrete 12-month preprocedural ipsilateral symptom type: stroke, transient ischemic attack (TIA), transient monocular blindness (TMB), or asymptomatic (ASX). Risk-adjusted odds ratios (ORs) were used to compare the likelihood of the 30-day outcomes of death, stroke, and myocardial infarction (MI) and the composite outcomes of death + stroke and death + stroke + MI. Results: Symptom type significantly influences risk-adjusted 30-day outcomes for carotid intervention. Presentation with stroke predicted the poorest outcomes (death + stroke + MI composite: OR, 1.3; 95% confidence interval [CI], 0.83-2.03 vs TIA; OR, 2.56; 95% CI, 1.18-5.57 vs TMB; OR, 2.12; 95% CI, 1.46-3.08 vs ASX), followed by TIA (death + stroke + MI composite: OR, 1.97; 95% CI, 0.91-4.25 vs TMB; OR, 1.63; 95% CI, 1.14-2.33 vs ASX). For both CAS and CEA patients, presentation with stroke or TIA predicted a higher risk of periprocedural stroke than in ASX patients. Presentation with stroke predicted higher 30-day risk of death with CAS but not with CEA. MI rates were not affected by presenting symptom type. The 30-day outcomes for the TMB and ASX patient groups were equivalent in both treatment arms. Conclusions: Presenting symptom type significantly affects the 30-day outcomes of both CAS and CEA in contemporary vascular surgical practice. Presentation with stroke and TIA predicts higher rates of periprocedural complications, whereas TMB presentation predicts a periprocedural risk profile similar to that of ASX disease.
