This is an ultrasound that focuses on the veins of the legs. It is done in the office by a trained sonographer (ultrasound technologist). The ultrasound uses sound waves to see how blood flows through the veins of the legs. This study specifically checks for venous insufficiency or varicose veins.

Chronic venous insufficiency

This is a condition in which the veins are not working properly, making it hard for blood to return to the heart from the legs. Many different things can lead to and worsen this condition, such as varicose veins, prolonged standing, pregnancy, heredity, and blood clots in legs (DVT). Chronic venous insufficiency can progress, leading to ulcers, swelling, and skin color changes.

Varicose veins

These are blue, red, or flesh colored veins that have grown large. They develop when blood pools in the legs when veins are not working correctly to carry blood to the heart from the legs. Varicose veins may look like twisted or bulging cords under the skin. Frequently they are raised above the skin.
