Carotid Artery Stenosis

Carotid arteries are located in the either side of the neck region which supply blood to the brain.

Carotid artery stenosis

is a medical condition that occurs when these arteries become narrow and thick, thus, disturbing the normal blood supply. This condition generally affects elder people as they age and lead to a transient ischemic attack i.e a mini heart stroke.

Carotid artery stenosis

can happen due to many reasons. The major reason is plaque formation in artery walls due to excess built up of cholesterol that makes the path narrow for blood flow. Another factor is excess levels of platelets in the blood form blood clots in the arteries leading to the path blockage.

Carotid Artery Stenosis – Diagnosis

Carotis arery stenosis do not cause symptoms always and hence it is difficult to diagnose the condition in some cases. The doctor can diagnose by detecting the heart condition through a stethoscope or ultrasonography.

  • Stethoscope detection –

    In case of carotid artery stenosis, an abnormal sound known as bruit is heard with a stethoscope.

  • Carotid ultrasonography –

    An ultrasound probe is placed on the neck area where the carotid arteries are situated and the stenosis condition can be easily detected.

Carotid Artery Stenosis – Treatment

Carotid artery stenosis is treated depending on the degree of the condition and patient’s overall history.

  • Surgical treatment –

    This surgical treatment is suggested if the artery narrowing is up to 70% and more. The treatment procedure is called carotid endarterectomy, in which the plaque formed in the walls of arteries is removed.

  • Medications –

    If the artery narrowing is less than 50%, there’s no need to go for surgery and anti-clotting medications work.

  • Angioplasty –

    Another treatment option is carotid angioplasty, in which the stents or balloons are used to open the narrowed artery.
