WHAT IS A LOWER EXTREMITY

 VENOUS DUPLEX?

 

Lower extremity venous

duplex scan is a painless exam

that uses high-frequency sound

waves (ultrasound) to capture

images of internal veins that

return blood to the heart. During

an upper extremity venous duplex

scan, the veins in your neck,

shoulders, arms, and wrists are

viewed. During a lower extremity

venous duplex scan, the veins in

the legs and ankles are viewed.

 

A special jelly is placed on the

 area being examined while a wand-

 like device called a transducer is

passed lightly over the skin over

 the vein. Internal images of the

veins are shown on a screen,

recorded as a video or printed

 as a photo.

 

A Doppler ultrasound may also

 be performed to capture images

 of the movement of blood through

 your veins. This test helps to

determine how the blood is

flowing through your veins.

 

Venous duplex scans can show

blood clots in leg veins and

 evaluate for abnormal veins

causing varicose veins.
