Non Invasive Lower Extremity Arterial Exams (LEA)

Segmental limb pressures are measured by combining Doppler ultrasound with blood pressure measurements at various locations in the arms and legs. By detecting differences in blood pressure at specific locations in different limbs, this test helps to diagnose arterial blockages and other circulation problems. It is most commonly performed in people suspected of having peripheral arterial disease (PAD) which is the narrowing of arteries in the legs due to the accumulation of plaques (atherosclerosis) and is oftern characterized by leg pain upon exercise.
