Vascular Screening


Vascular Screening

The main investigation for vascular screening is by performing a carotid ultrasound to test for narrowed carotid arteries, which increase the risk of stroke.

Carotid arteries are usually narrowed by a buildup of plaque — made up of fat, cholesterol, calcium and other substances that circulate in the bloodstream. Early diagnosis and treatment of a narrowed carotid artery can decrease stroke risk.

Your doctor will recommend carotid ultrasound if you have transient ischemic attacks (TIAs) or certain types of stroke and may recommend a carotid ultrasound if you have medical conditions that increase the risk of stroke, including:

  • High blood pressure

  • Diabetes

  • High cholesterol

  • Family history of stroke or heart disease

  • Recent transient ischemic attack (TIA) or stroke

  • Abnormal sound in carotid arteries (bruit), detected by your doctor using a stethoscope

  • Coronary artery disease

To screen for narrowed or blocked blood vessels in other areas of the body, you may need additional tests, including:

  • Abdominal ultrasound. You may have an abdominal ultrasound to test for conditions affecting the blood vessels or organs in your abdominal area.

  • Ankle-brachial index test. This test measures and compares the blood pressure between your ankle and your arm. The test shows reduced or blocked blood flow to your legs.

  • Cardiac stress test. This test shows how well your heart performs when under stress, such as during exercise. Results can indicate poor blood flow to the heart.

Your doctor may also order imaging tests to detect coronary artery disease.

Other uses of carotid ultrasound

Your doctor may order a carotid ultrasound to:

  • Evaluate blood flow through the artery after surgery to remove plaques (carotid endarterectomy)

  • Evaluate the placement and effectiveness of a stent, a mesh tube used to improve blood flow through an artery

  • Locate a collection of clotted blood (hematoma) that may prevent blood flow

  • Detect other carotid artery abnormalities that may disrupt blood flow
