Carotid Artery

The carotid arteries are the blood vessels located on both sides of your neck that carry blood to the head and brain.

Carotid artery disease

Carotid artery disease is a frequent source of the stroke. The lining of a normal carotid artery is smooth, but the inner walls of arteries narrowed by atherosclerosis can be very rough for irregular because fatty material called plaque collects inside the artery. Special components of the blood called platelets can dump on this irregular surfaces, small pieces if plaque or platelet clots can then travel to the brain, blocking blood flow to a portion of the blood flow to a portion of the brain and causing a stroke.

Stroke

A stroke occurs when a part of the brain is without blood for a prolonged period of time. That part of the brain becomes permanently injured. Causing difficulty with movement of the arms or legs, speech or vision. The specific disability that results is dependent upon which part of the brain and how large an area is affected. .

Transient ischemic attack

Sometimes called a mini- stroke, a translent ischemic attack (or TIA) is the temporary blockage of blood to a portion of the brain (or eye) that results in specific warning signs similar to stroke symptoms (see below) . The symptoms last less than a day, and generally this does not result in permanent injury to the brain. Although these symptoms resolve quickly, they are an important sign that someone is at high risk to develop a full- blown stroke if ignored. .

  • Magnetic resonance angiography (MRA) which uses magnetic Waves and magnetic energy.
  • Conventional Angiogram which uses a series Of X-ray images with dye injected into the arteries to show the flow of blood.

 

Carotid Artery Disease Treatment

  • Medicines
  • Control of
    • Diabetes
    • Hypertension
    • Cholesterol
  • Surgical Removal of the blockage causing plaque : Carotid endarterectomy
  • ballooning and stenting of the narrowed arteries with a protective fliter to the prevent clots from damaging the Brain.
