Up to one-third of strokes are caused by carotid artery disease, a buildup of plaque in the main arteries in the neck that supply oxygen-rich blood to the brain. Without treatment, this buildup can slow blood flow or dislodge plaque that travels to the brain, causing a stroke.
Some people with carotid artery disease require surgery to treat this issue. CentraState now offers a minimally invasive surgical option called transcarotid artery revascularization (TCAR) that not only helps prevent future strokes – it also lowers the risk of stroke during the procedure compared to open surgery.
“The availability of TCAR means that more people have access to a less invasive surgical treatment, including older, more fragile patients who may be at too high risk for open surgery,” says CentraState vascular surgeon Habib Khan, MD, one of the few physicians in the region to offer the procedure. “TCAR takes significantly less time, usually only requires twilight sedation and has a quicker recovery time with fewer complications. Patients can return home the next day and usually only need over-the-counter pain relievers.”
Reversing Blood Flow is Key
During the procedure, Dr. Khan inserts a catheter (tiny tube) into the carotid artery through a small incision above the collarbone. The tube connects to a system that is used to temporarily reverse blood flow away from the brain. This prevents any plaque debris from reaching the brain and causing a stroke during the procedure. The blood is filtered to remove any debris before it’s returned to a vein in the groin. Dr. Khan then places a stent inside the carotid artery to stabilize the plaque, minimizing the risk of a future stroke.
“Blood flows safely away from the brain for just a few minutes, giving our surgical team complete control,” explains Dr. Khan. “The stent is placed while the brain is protected.”
At CentraState, TCAR is available to any eligible patient requiring surgical treatment of carotid artery disease.
“Patients don’t have to travel for this innovative procedure – we’re bringing it right to their doorstep,” adds Dr. Khan.
