TransCarotid Artery Revascularization (TCAR)
New minimally-invasive treatment option for carotid artery disease
Stroke is the number five cause of death and a leading cause of disability in the United States. Carotid artery disease is a leading cause of ischemic stroke. Advanced carotid atherosclerosis represents a risk of stroke from low flow and/or plaque rupture that can be reduced or prevented by carotid intervention in combination with medical treatment
Community Heart and Vascular Hospital has a new innovative treatment for patients at risk for stroke from carotid artery disease. This minimally invasive procedure, called TransCarotid Artery Revascularization or TCAR, utilizes a new FDA-approved ENROUTE® Transcarotid Neuroprotection System (NPS) to decrease the risk of stroke associated with carotid intervention. During the procedure, flow is temporarily reversed in the carotid artery and dangerous pieces of plaque and blood clots are safely diverted away from the brain minimizing the risk of stroke.
The standard treatment option for advanced carotid artery disease is carotid endarterectomy (CEA), an open surgical procedure. This surgical technique is quite durable with a low stroke rate, but does involve a large incision on the neck (see illustration) and an associated risk of cranial nerve injury that can result in difficulty with swallowing, speaking and sensation in the face.
Transfemoral carotid stenting is another option for the treatment of symptomatic carotid artery disease, but is associated with a high risk of stroke compared to carotid endarterectomy.
TCAR is a combination of open surgery and carotid stenting that provides many benefits to patients including a quicker recovery, less pain and reduced risk of complications.

Community Heart and Vascular offers several vascular surgeons specially trained in TCAR:
TCAR has demonstrated the lowest stroke rate of clinical studies to-date and is a clinically-proven alternative to carotid endarterectomy and transfemoral carotid stenting.
Watch the video below to learn more about how the TCAR procedure works.
A small incision is made at the base of the neck, just above the collarbone. A puncture is made into the common carotid artery and the stent delivery sheath is positioned under fluoroscopic guidance. The Enroute® neuroprotection system is connected and blood flow is reversed in the carotid system and directed away from the brain. The blood is filtered and then returned to the patient via a second access in the femoral vein. During this brief period of flow reversal, a stent is placed across the carotid lesion to stabilize the plaque and maintain long term carotid patency. Flow reversal is discontinued and the treated area is evaluated angiographically.
The average procedure time is less than an hour. The procedure can be done under general anesthesia or with local anesthesia to decrease cardiopulmonary risk. Patients are held overnight for observation.
