Chronic Venous Insufficiency

Chronic venous insufficiency is a condition in which the leg veins do not allow enough blood to travel back to the heart. Valves in the deeper leg veins normally keep blood moving back toward the heart, but with chronic venous insufficiency, vein walls are weakened and valves are damaged. It is a long-term condition and often occurs when a vein is partly blocked or blood is leaking around the valves of the vein. Vein problems can cause blood to flow in both directions, prompting blood to pool in the legs. It is not a serious health threat, but it can be disabling and painful. The condition also can lead to venous stasis ulcers, in which the lack of circulation causes areas of the skin to die and open, or ulcerate, usually below the knees and most commonly around the ankles.


UAB Medicine’s vascular specialists provide expert treatment of all types of circulatory conditions using a broad range of services, including medical therapy, minimally invasive endovascular procedures, and open surgical reconstruction. Our specialty-trained surgeons and physicians are leaders in their field and have excellent track records in treating some of the most complex vascular diseases and conditions. That expertise is backed by the latest and most advanced technology, facilities, and treatment options, as well as our dedication to patient-centered care. A wide range of specialists work together through the UAB Advanced Limb Preservation program to prevent the need for amputation, preserve maximum function in the lower limbs in people with peripheral artery disease (PAD), and treat associated medical conditions such as diabetes.

Our vascular experts confer extensively with each patient to determine a specific diagnosis and treatment plan based on medical history, physical exam, and a variety of non-invasive testing that includes ultrasound, Doppler with plethysmography, CT scans, and magnetic resonance angiography (MRA). We also employ three-dimensional overlay fusion technology, in which pre-operative imaging is overlaid with images captured during surgery, providing greater accuracy and improved outcomes. In addition, we maintain an operating room designed specifically for vascular therapies, where we perform “hybrid” procedures that combine both open surgery and minimally invasive endovascular techniques and maximize the benefits of both.

As a major academic medical center, UAB maintains an active research program that also manages clinical trials. Our commitment to innovation and discovery often means that patients have access to advanced new treatments long before they are available to the general public.
