How is your vascular condition diagnosed?

When referred to BASS vascular team, they will order quick and painless blood flow measurements.  These test will take place at one of our vascular offices to determine the best treatment option for the patients. Our physicians will recommend one, or all of the following diagnostic tests for your condition.

Ankle-Brachial Index

The ankle-brachial index (ABI) is an efficient tool for documenting the presence of lower-extremity peripheral arterial disease (PAD).  It measures blood pressure around a patient’s ankles and arms.  The two measurements are then compared to determine adequate circulation in the legs.  An ABI less than 0.09 suggests a need for further vascular evaluation(s).  Identified disease can be further evaluated by a duplex ultrasound and/or angiogram.

Duplex Ultrasound

Duplex ultrasound is a non-invasive way to determine pathology. The ultrasound evaluates both the blood flow and structure of your vessels. The ultrasound will produce images that can be color coded to display the direction of blood flow, speed, diameter of vessels and areas that might be blocked.


An angiogram takes x-ray images of narrowed, blocked, enlarged, malformed arteries, in all parts of the body.  To perform and create an x-ray, your vascular physician will thread a hollow catheter into the desired artery or vein.  Dye (known as contrast) is then injected into the catheter to make the blood flowing in vessels visible on an x-ray.  Several images will be created in order to track where the disease is located in your body.  The contrast is later eliminated from your body through your kidneys and your urine.
