Transcarotid Artery Revascularization (TCAR)

Transcarotid artery revascularization (TCAR) is a minimally invasive approach to treat carotid artery disease. The procedure begins with a small incision just above the collarbone to allow access to the carotid artery. A short hollow tube (sheath) is placed in the carotid artery. To protect the brain from plaque debris during the procedure, a circuit outside the body directs the blood flow away from the brain, collecting any potential debris in the device filter, before returning the blood safely back into a vein in the leg. This “reverse flow” and allows the physician to place a stent (an expandable mesh tube) at the site of the disease for long-term plaque stabilization and stroke prevention. TCAR is well suited for patients who are higher risk of surgical complications due to age, pre-existing conditions, or anatomical issues.
