TransCarotid Artery Revascularization (TCAR) is a unique medical procedure designed to reduce the risk of stroke,
particularly in patients who are deemed at high risk for traditional carotid endarterectomy (CEA). This innovative
procedure has emerged as an important alternative for carotid revascularisation, offering a less invasive approach
with potentially fewer complications.
TCAR is used in the treatment of carotid artery disease, a condition where fatty deposits, or plaques, clog the
carotid arteries — the main vessels that supply blood to the brain. This condition is a significant risk factor for
stroke. Traditional treatment options, like CEA and carotid artery stenting (CAS), while effective, come with certain
risks, especially for patients with heart or lung conditions, or those who previously had neck radiation or surgery.
TCAR is performed through a small incision at the neckline just above the clavicle. This approach temporarily
reverses the flow of blood away from the brain to protect against plaque that may come loose during the procedure.
Blood is filtered outside the body and returned through a second incision in the groin. This protective flow reversal
is key to reducing the risk of stroke during the procedure.
TCAR boasts several advantages over traditional methods. It is less invasive, has a lower risk of surgical
complications, and the recovery time is generally shorter. Patients usually experience less pain and scarring due to
the smaller incision and can expect a quicker return to normal activities.
Clinical trials and studies have shown TCAR to be both safe and effective. It significantly reduces the risk of stroke
both during and after the procedure compared to other treatments. For patients at high risk for conventional surgery
due to age, medical history, or anatomical issues, TCAR presents a safer alternative.
These potential risk of TCAR include nerve injury, bleeding, or problems related to blood flow reversal. However,
these risks are relatively low, especially when weighed against the potential benefits for patients at high risk of
stroke.
