This study states that Previously published results of carotid revascularization with both transfemoral stenting and endarterectomy have demonstrated inferior perioperative stroke and death outcomes in neurologically symptomatic patients compared with those without symptoms. This study was completed to establish the real-world, symptom-based perioperative and follow-up outcomes for transcarotid artery revascularization (TCAR).

An institutional retrospective review of all TCARs performed outside of clinical trial regulations from 2016 to 2019 was completed. Eligible patients were classified as symptomatic or not based on a history of a unilateral neurologic deficit attributable to an extracranial carotid artery lesion within the previous 180 days. Univariate analysis consisting of Fisher’s exact and Student t-tests, as appropriate, were performed between cohorts. Kaplan-Meier analysis was completed to estimate the stroke-free survival at 1 year postoperatively. Within the investigational period, 167 patients (85 symptomatic) qualified for study inclusion. Baseline demographics were roughly equivalent. In this institutional series of patients undergoing TCAR, we found that symptomatic patients have a similar perioperative risk of stroke and myocardial infarction as asymptomatic patients. However, we did observe a strong statistical trend suggesting a higher mortality risk in symptomatic patients. There was no difference between cohorts with respect to 1-year stroke-free survival.
