WHAT IS A LOWER EXTREMITY

 ARTERIAL DUPLEX?

 

Lower extremity arterial duplex is

a painless exam that uses high-

frequency sound waves

(ultrasound) to capture internal

images of the major arteries in the

 arms, legs, and neck. A special

jelly is placed on the area being

 examined while a wand-like

device called a transducer is

passed lightly over the skin above

 the artery. Internal images of

arteries are shown on a screen and

 can be recorded as a video and

printed as a photo.

 

A Doppler ultrasound may also be

 performed to capture images of

 the movement of blood through

your arteries. This test helps to

 determine how the blood is

flowing through your arteries.

Arterial duplex can show plaque

built up in arteries to help detect

peripheral vascular disease (PVD).
