New Minimally Invasive Procedure Prevents Stroke –
Cardiovascular surgeon Dr. Uttam Tripathy and vascular surgeon Dr. Imran Mohiuddin performed the first minimally invasive procedure to treat carotid artery disease and prevent future strokes using a new procedure called TransCarotid Artery Revascularization (TCAR). TCAR is a clinically proven, minimally invasive and safe approach for high surgical risk patients who need carotid artery surgery for blockages.
Carotid artery stenosis is a form of atherosclerosis, or a buildup of plaque, in the two main arteries in the neck that supply oxygen-rich blood to the brain. If left untreated, carotid artery disease can often lead to stroke; it is estimated to be the source of stroke in up to a third of cases, with 400,000 new diagnoses of the disease made every year in the U.S. alone.
“TCAR is an important new option in the fight against stroke and is particularly suited for the large portion of patients who are at higher risk of complications from carotid surgery due to age, anatomy or other medical conditions,” said Dr. Tripathy. “Because of its low stroke risk and faster patient recovery, I believe TCAR represents the future of carotid repair in a vast majority of patients.”
TCAR is unique in that blood flow is temporarily reversed during the procedure so that any small bits of plaque that may break off are diverted away from the brain, preventing a stroke from happening. A stent is then placed inside the artery to stabilize the plaque, minimizing the risk of a future stroke.
“It seemed so easy compared to the other surgeries I’ve had, and the recovery was much faster,” said Susan White, who was considered too risky for traditional surgery. “I was out of the hospital the day after the procedure with a much smaller scar than I expected. I feel great and am looking forward to getting the other side done very soon.”
Prior to TCAR, the main treatment option for severe carotid artery disease was an open surgical procedure called Carotid Endarterectomy (CEA). CEA removes plaque from inside the carotid artery to restore normal blood flow to the brain, but an incision leaves a visible scar on the side of the neck and carries risks of surgical complications, including bleeding, infection, heart attack and cranial nerve injuries that can cause issues with swallowing, speaking and sensation in the face.
The TCAR procedure was developed by Sunnyvale, California-based Silk Road Medical, Inc. and includes the ENROUTE® Transcarotid Neuroprotection (NPS) and Stent System – the first devices designed and FDA-approved specifically for TCAR. Over 10,000 TCAR procedures have been performed worldwide through clinical trial and commercial use. TCAR has been studied extensively, and the clinical data have been excellent.
