 Ultrasonography of chronic venous insufficiency of the legs

Ultrasonography, particularly Doppler ultrasonography, is a non-invasive imaging technique commonly used to assess chronic venous insufficiency (CVI) of the legs. CVI is a condition where the veins have difficulty returning blood from the legs back to the heart, leading to a variety of symptoms such as swelling, pain, varicose veins, skin changes, and, in severe cases, ulcers.
