Carotid stents offer a less-invasive option for clearing blocked neck arteries and reducing risk of stroke

Chicago, Illinois- Specialists at Rush University Medical Center performed a carotid stent procedure live on the internet September 28th at 4 p.m.(CDT). The procedure is a minimally invasive approach to opening blockages in the main blood vessels that supply blood to the brain. The buildup of fatty plaques and blood clots in the carotid arteries can lead to a stroke.

Previously, such blockages could only be cleared with a surgical procedure called carotid endarterectomy, in which surgeons cut into the neck artery to remove the plaque. The newer procedure involves only a small incision in the groin. Using fluoroscopy or x-ray, a catheter is inserted through the femoral artery and up to the site of the blockage in the neck.

During the live internet broadcast, Dr. Chad Jacobs, vascular surgeon, and Dr. Hector Ferral, interventional radiologist, employes the use of the Guidant RX ACCUNET™ Embolic Protection System. The device features a filter basket that is designed to trap particles of plaque that might be dislodged during the procedure, potentially leading to stroke and other complications.

“Using a wire the width of a hair, we thread the filter through the catheter past the blockage site. Once in place, the filter opens like an umbrella to expand against the artery walls,” said Ferral. ‘The filter prevents debris from traveling to the brain, thereby significantly decreasing the risk of stroke.”

Following placement of the net, a balloon catheter is delivered to the site and expanded to press plaque against the artery walls. A third catheter delivers a stent to the site. The stent is put into place by removing a protective covering, automatically expanding the stent in the vessel.

“The stent remains in place to help keep the vessel open,” said Jacobs. “Plaque that is dislodged during the procedure is captured by the protective net, which is then collapsed and removed.”

The patient usually remains conscious while the stent is implanted at the site of the blockage. Patients are up and walking within a few hours, however, they are often kept overnight for observation.

This is the second live internet broadcast this year for Jacobs. In June, Jacobs and Dr. Walter McCarthy, section chief of vascular surgery, performed the VNUS Closure® procedure for varicose veins live for a web audience.

“We received tremendously positive feedback from fellow doctors, patients and the general public. I see this live webcast as an opportunity to showcase the collaboration across specialties at Rush,” said Jacobs. “Patients with a complicated procedure benefit from having both cardiovascular surgeons and interventional radiologists in the operating room.”

“Working together, we can handle any complications that may arise during a procedure assuring excellent patient care,” said Ferral.

Carotid artery stenting is FDA approved for patients who are high-risk candidates for open surgery. High-risk patients include those with significant heart, kidney or lung disease, recurrence of a blockage following a prior carotid surgery, or with difficult-to-access neck anatomy.

Rush University Medical Center is a participant in numerous clinical trials, under the direction of Dr. Jeffrey Snell, interventional cardiology; Dr. Walter McCarthy, vascular surgery; and Dr. Demetrius Lopes, endovascular neurosurgery, to determine the effectiveness and safety of carotid stents in expanded patient populations.

According to the American Heart Association, stroke is the third leading cause of death in the United States and the number one cause of disability in adults. Approximately 25 percent of strokes are caused by carotid artery disease. A stroke can occur if the artery becomes blocked, a piece of plaque breaks off and travels to the smaller arteries of the brain, or a clot forms and blocks a narrowed artery. Carotid artery disease may not have symptoms, so it is important for those at risk to have regular physical exams by their doctor.
