Vascular ultrasound is a noninvasive procedure used to evaluate the circulation in the blood vessels of the body. 

As a non-invasive procedure, it doesn’t require any anesthesia or needles. Unlike other imaging tests, vascular ultrasound does not involve radiation or contrast dye.

What happens during a vascular ultrasound?

Vascular ultrasound uses high-frequency sounds to create images of arteries and veins. These sound waves are transmitted through the examined tissues. The sounds reflect off blood cells moving within the blood vessel. They are then recorded and displayed on a computer screen, creating an image of the blood vessel.

The speed of the sound waves returning to the ultrasound machine enables calculation of the speed of blood flow in a blood vessel. Slow return of the sound waves may indicate a blockage. 

When is it performed?

This procedure is usually recommended when a blood clot is suspected. A doctor may also suggest this test to look for chronic venous insufficiency, as part of preparation for endovascular surgery (for patients with peripheral artery disease), and to monitor stents and grafts for any sign of returning blockage.

Is there any special preparation for it?

Most vascular ultrasound procedures do not require advanced preparation except for the following:

Abdominal Vascular Ultrasound

  • Do not eat or drink 8 hours before the procedure.
  • Take your medications with small sips of water.
  • If you’re diabetic, take your insulin.

Aortic, Iliac Vena Cava, or Renal Artery Stenosis Vascular Ultrasound

  • Do not eat or drink 6 hours before the exam.
  • Take your medications with small sips of water.
