Segmental arterial Doppler pressures: A test that uses Doppler ultrasound to measure the blood pressures in the legs to make sure there is normal blood flow. The test is usually done when there is intermittent claudication (leg pain on exercise).

Normally the blood pressures in the legs are similar to those in the arms. Lower pressures in the legs usually mean there are plaques (cholesterol deposits) in the leg arteries compromising the circulation. Blood pressure measurements are therefore made at different locations on the legs to see if there is narrowing of the arteries and where the blocks are in the legs. The test is often done in people with diabetes, because diabetes tends to cause small vessel disease.
