Carotid & Extremity Vascular Testing

What's it for?

When fatty deposits build up on the arteries in your neck, arms or legs, these blood vessels can begin to narrow or harden. This is called peripheral vascular disease (PVD), also commonly referred to as peripheral arterial disease (PAD).

Depending on the location of the blockage, peripheral vascular disease can lead to strokes, transient ischemic attacks (TIA) or pain in the legs during walking (claudication).

Carotid and vascular extremity testing can help to identify peripheral vascular disease and help guide your doctor in its treatment.

Duplex ultrasound can be used to diagnose and investigate:

  • PAD in the legs
  • Carotid (neck) artery disease
  • Kidney artery disease
  • Deep vein thrombosis (DVT)
  • Chronic vein disease and varicose veins

How it's done

The primary test for peripheral vascular disease is ultrasound. This is a Noninvasive and completely painless way for your doctor to assess the blood flow through important arteries. This procedure does not require the use of needles, dyes, radiation or anesthesia.

In the case of a carotid ultrasound, a sensor is placed on the side of your neck. In the case of a leg ultrasound, the probe is placed on the outside of your legs. Sound waves are then bounced off your blood vessels, creating a picture of the blood flowing through them and revealing any blockages.

This test typically takes from 30 to 60 minutes.

Other tests used to diagnose peripheral arterial disease are:
