How do we determine if you have arterial blockages?

There are some relatively simple tests that can be done to determine if your arterial blood flow in you legs is normal.

Segmental Pressure Test

In this test the blood pressure at several points in your leg is checked using a blood pressure cuff and a Doppler. Then, you are asked to walk on a treadmill, following which your ankle pressure will be taken again to determine if the pressure decreased when you walked.

Ultrasound Scan

The scan produces images of arteries on a screen and is used to evaluate the blood flow, locate blockages, and measure the size of the artery.


In this test dye is injected into the arteries while X-rays are taken. The dye “lights up” the arteries allowing the area of blockage to be accurately pinpointed.
