Upper and Lower Arterial Duplex

Duplex ultrasound is used to get an overall view of vascular disease in the arteries of the upper and lower extremities. For the lower extremities, the Doppler evaluation starts from the iliac vessels and goes all the way down to the foot. For the upper extremities, it starts from the subclavian artery and goes down to the wrist.

We use Doppler measurements to check for narrowing in certain areas of the body. We measure the blood flow before, during, and after the narrowest point.

Duplex imaging measures the length of the blockages in blood vessels and checks if the small vessels further down the artery are open. It can also help figure out if the leg pain is caused by problems with the blood vessels, muscles or nerves.
