Services & Treatments TCAR TransCarotid Artery Revascularization TCAR is a clinically proven procedure to treat patients with carotid artery disease who are at risk with the traditional carotid endarterectomy (CEA). Unlike CEA, TCAR is minimally invasive. This FDA approved neuroprotection system is delivered directly into the common carotid artery, temporarily reversing blood flow in the carotid artery during stent placement. This helps to prevent dangerous bits of plaque from dislodging and traveling to the brain where they could cause a stroke. TCAR is appropriate for patients who are at higher risks of complications from CEA due to age, other medical conditions or anatomical issues.
