Peripheral vascular ultrasound is a test used to evaluate the health of blood vessels. Ultrasound uses sound waves to capture images of structures inside the body. It is similar to the use of sonar in submarines.

The test may be used to investigate the cause of the following symptoms:

  • Pain
  • Swelling
  • Increased warmth or coolness in the extremity
  • Difficulty finding pulses
  • Bulging veins

It may also be used to diagnose the cause or severity of:

  • Poor circulation due to blocked or narrowed blood vessels
  • Blood clots
  • Poor blood vessel function
