Carotid Artery Disease

Carotid Artery Disease Treatment | Carotid Stent East Bay CA | Contra Costa County

The pair of carotid arteries in the neck carry blood from the heart to the brain. Carotid artery disease occurs as a result of the build-up of plaque that hardens the artery, a condition called atherosclerosis. The blockage can narrow the artery restricting blood flow, increasing a person’s risk of having a stroke. A piece of the blockage can also break off and lodge in the artery or in a smaller vessel.

Carotid artery disease develops over time. As a result it is not always diagnosed until the patient has had a stroke or a transient ischemic attack (TIA), also known as a ministroke.

Symptoms of Carotid Artery Disease

Carotid artery disease does not always cause symptoms. The first alert that you have a blocked carotid artery could be a stroke. Some people do experience warning signs. These come in the form of transient ischemic attacks, or TIAs.

During a TIA, you may experience the following symptoms:

  • Tingling
  • Weakness
  • Slurring of speech
  • Loss of vision in one eye
  • Numbness or loss of control on one side of your body

These symptoms are temporary and usually disappear within an hour. Nevertheless, they should be reported to your doctor immediately. If these symptoms last more than a day, you may have had a stroke.

Treatment of Carotid Artery Disease

Carotid surgery is performed to clear a blockage in the carotid artery and restore blood flow to the brain. Carotid surgery procedures may take the form of an endarterectomy or an angioplasty with stent placement.

Carotid Endarterectomy Procedure

An endarterectomy surgically removes diseased material and clogged deposits from the inside of an artery to restore normal blood flow. When the procedure is performed on the carotid artery, it is called a carotid endarterectomy. By keeping blood flow open to the brain, a carotid endarterectomy helps prevent the occurrence or recurrence of stroke.

Carotid Stenting

Carotid stenting involves the implantation of a metal mesh tube, or stent, to hold a clogged artery open so blood can flow through it unobstructed. The stent is put in place using a balloon angioplasty procedure. A small tube, known as a catheter, with a tiny balloon on the end is inserted into an artery in the groin, threaded up to the carotid artery and gently expanded, pushing open the blockage and restoring blood flow. The stent is then put in place to ensure that the artery stays open.

Stenting for carotid artery disease is usually recommended for patients with severe stenosis, or blockage, who experience symptoms from the restricted blood flow.
