Overview

Trans Carotid Artery Revascularization, or TCAR for short, is a minimally invasive procedure that involves placing a small incision at the base of the neck to allow direct access to the carotid artery, providing safer delivery of the stent to the diseased artery. Comparatively, traditional stenting involves the delivery of the stent from the groin.

The TCAR procedure places a soft, flexible sheath directly into the artery and connects to the ENROUTE® Transcarotid Neuroprotection and Stent System, which reverses the flow of blood away from the brain, protecting it from pieces of plaque that may come loose during the procedure. This blood is filtered and returned through a second sheath placed in the femoral vein in the patient’s thigh.

While the blood flow is reversed with the Neuroprotection system, balloon angioplasty and stenting can be performed. When the stent is placed and stabilizes the plaque in the carotid artery, flow reversal is turned off to allow blood to flow to the brain as it normally does.

Who is a candidate?

While TCAR can be used to treat most cases of carotid artery disease, particularly patients who are at high risk of surgical complications because of their age, anatomy or other medical conditions.

What to expect

TCAR is a safer way to use stents to treat carotid artery disease. While it is a revolutionary procedure, TCAR at present is not intended to replace surgery. Rather, it’s meant to be a safer alternative to stent placement in patients deemed high risk for standard surgical repair. TCAR patients usually are kept in the hospital overnight for observation and typically leave one day after the procedure. They can return to full and productive lives and their risk of stroke in the future is dramatically reduced.
