BACKGROUND: Transcarotid artery revascularization (TCAR) has been proposed as a alternative to carotid endarterectomy (CEA) and transfemoral carotid artery stenting in high-risk patients. Recently Centers for Medicare and Medicaid Services expanded coverage for TCAR to include standard surgical risk patients within the Society of Vascular Surgery Vascular Quality Initiative TCAR Surveillance Project. Few single centers compared the clinical outcome of TCAR with CEA. This study compares 30-day perioperative clinical outcomes between TCAR and CEA. STUDY DESIGN: This is retrospective analysis of prospectively collected data from the TCAR Surveillance Project of TCAR patients enrolled in our institution and compared with CEAs done in the same time/with the same providers. The primary outcome was stroke and/or death. Secondary outcomes included stroke, death, MI, cranial nerve injury, bleeding, and others. Propensity matching was done to analyze outcomes. RESULTS: The study analyzed 501 patients (347 CEA, 154 TCAR). There were no significant differences in symptomatic status (43% for CEA vs 38% for TCAR, p = 0.303). TCAR had more patients with hypertension (p = 0.04), coronary artery disease (p = 0.028), and congestive heart failure (p = 0.039). The 30-day perioperative complication rates for CEA vs TCAR were as follows: stroke 1% vs 3% (p = 0.142), stroke/death 1% vs 3% (p = 0.185), MI 0.6% vs 0.7% (p = 1), death 0.6% vs 0% (p = 1), stroke/death/MI 2% vs 4% (p = 0.233), cranial nerve injury 4% vs 2% (p = 0.412), and major hematoma (requiring reintervention) 2% vs 3% (p = 1). After matching 154 CEA patients and 154 TCAR, 30-day perioperative complication rates were as follows: stroke 2% vs 3% (p = 0.723), stroke/death 3% vs 3% (p = 1), death 1.3% vs 0% (p = 0.498), MI 0.7% vs 0.7% (p = 1), and stroke/death/MI 3% vs 4% (p = 0.759). CONCLUSIONS: This study showed that using propensity match analysis, both CEA and TCAR have similar 30-day perioperative outcomes. Further long-term data are needed.
