Transcarotid artery revascularization (TCAR)

Transcarotid artery revascularization (TCAR) is a minimally invasive surgical procedure used to treat carotid artery disease, a condition where the carotid arteries in the neck become narrowed or blocked, typically due to atherosclerosis. The carotid arteries are major blood vessels that supply oxygen-rich blood to the brain, and blockages in these arteries can increase the risk of stroke. During a TCAR procedure, a vascular surgeon makes a small incision in the neck to access the carotid artery. A soft, flexible tube called a sheath is then inserted into the artery. Blood flow is temporarily reversed, diverting blood away from the brain to a system that filters and removes any potential debris or plaque. This reduces the risk of embolization, where debris from the artery can travel to the brain and cause a stroke. Once the blood flow has been reversed, a stent is inserted into the artery to widen it and improve blood flow. The stent is then deployed, and blood flow is restored to its normal direction. The entire procedure is performed under local anesthesia, and most patients can go home the same day or the next day. Vascular surgeons perform TCAR procedures to treat carotid artery disease and reduce the risk of stroke in patients who are at high risk for complications from traditional carotid endarterectomy surgery. TCAR offers several potential advantages over traditional surgery, including a smaller incision, reduced risk of nerve damage, and faster recovery times. It is particularly beneficial for patients who may not be suitable candidates for traditional surgery due to factors such as age, anatomy, or other medical conditions. Overall, TCAR is a safe and effective treatment option for carotid artery disease, and vascular surgeons perform these procedures to help reduce the risk of stroke and improve the quality of life for their patients.
