Quick Facts

What is Varicose Ulcer ?

A venous ulcer, sometimes called a varicose ulcer, is a leg wound that happens when the leg veins don’t circulate blood back toward the heart. Blood can back up in the veins, building up pressure on the skin, which can cause an open sore to form.

Venous ulcers usually form on the sides of the lower leg, above the ankle and below the calf. They are slow to heal and often return. Without proper treatment, they can become larger and cause additional leg problems.

Venous Ulcer Signs and Symptoms

Venous ulcer (varicose ulcer) symptoms include:

  • Dark red or purple skin patches that can be thick, dry and itchy
  • Swollen and achy legs
  • A shallow, red sore with irregular edges which may also have clear, yellow or bloody drainage

Diagnosis

If a venous ulcer is suspected, your physician will do a complete physical, including a check of your blood pressure in your arm and your ankle. Accurate diagnosis is the foundation of good ulcer care. The diagnosis is typically made based on the description of how the ulcer began and physical exam findings. Additional tests may include:

Ankle brachial index test: During this test, blood pressure cuffs are placed on the arms and ankles. A handheld ultrasound device or ‘Doppler’ is used to listen to the blood flow and measure the blood pressure. This helps doctors understand if there is a decreased blood flow to the lower legs and feet.

Ultrasound: An ultrasound device can measure blood pressure on various points of your arm or leg, which will help the physician determine if you have any blockages and how quickly blood flows through your arteries in the lower leg.

In addition, ulcers should be assessed for infection. A culture of the wound may be used to determine if antibiotics are needed. In addition, these tests may also be used:

Imaging tests: X-rays, magnetic resonance imaging (MRI), or bone scans can help identify bone infection and help determine whether surgery is needed to remove all of the infection.

Venous ulcers have several causes, typically lifestyle factors or results. The following can lead to venous ulcers:

  • Obesity
  • Smoking
  • Standing or sitting for long periods

Risk Factors

Risk factors that can contribute to venous ulcers include:

  • Age: As you get older, your veins lose elasticity and the valves in your veins become weak, leading to venous ulcers.
  • Being female: Women develop venous ulcers more often than men.
  • Deep vein thrombosis: Blood clots that form in the deep veins of the leg can cause venous ulcers.
  • Family history: Venous ulcers may be hereditary.
  • Pregnancy: Pregnancy can sometimes cause pressure in the lower legs, which can lead to venous ulcers.
  • Varicose veins: Varicose veins can increase the risk of developing venous ulcers.
  • Venous insufficiency: When leg veins can’t circulate blood properly, blood pools in the legs and can cause venous ulcers.

Prevention

While you cannot prevent certain risks for venous ulcers, you can take steps to lower your chances of developing the condition:

Don’t smoke: If you do smoke, ask your physician about programs and strategies that can help you quit.

Control high blood pressure and cholesterol: Eat a healthy diet, exercise and take medications as prescribed.

Manage your diabetes: If you have diabetes, keep blood sugar levels under tight control.

Maintain a healthy weight: Eat a low-fat, low-sugar diet high in fruits and vegetables and exercise regularly to keep your weight stable.

Wear compression stockings: People with chronic venous insufficiency should wear compression stockings daily.

Avoid sitting or standing for long periods of time: Take regular breaks to walk and stretch.

With proper treatment, most venous ulcers heal within three to four months.

Treatment and Recovery

Treatment for venous ulcers includes controlling the high pressure in the leg veins and treating the ulcer.

Controlling Pressure in the Leg Veins

Controlling swelling is essential for patients with venous ulcers. Leg elevation, with the feet at or above the level of the heart, several times throughout the day and while sleeping, can help reduce swelling. Compression wraps or bandages are often applied to the legs. These can be changed as often as multiple times a day or as infrequently as once a week, depending on the amount of fluid draining from the ulcer. Once the ulcer is smaller or nearly healed, elastic compression stockings may be recommended. Compression stockings are sized to fit the legs and are typically put on in the morning and worn throughout the day. A venous pump may be prescribed for patients with severe swelling.

Treating the Ulcer

The first step in treating a venous ulcer is to remove any dead tissue around the sore and then to apply a special dressing to encourage healing. The dressing will need to be changed about once a week. Sometimes a compression stocking will be worn over top of the dressing. The first few weeks with a compression bandage on an ulcer are usually painful. Your doctor will prescribe and appropriate pain reliever. As the ulcer heals, the pain will lessen.

Surgery

Patients who have developed poorly healing sores in relation to their varicose veins require more advanced wound care and treatments. New varicose vein treatment options are minimally invasive, require minimal anesthesia and are safely performed in outpatient surgery centers or doctors’ offices. Treatment choices depend on the vein groups that are causing symptoms and can include:

  • Endovenous ablation: This procedure can be done as an outpatient. A catheter is inserted into the great or small saphenous vein. After numbing medication is injected into the skin along the area of the vein to be treated, the vein is heated with radio waves or a laser. This heating process, or ablation, takes less than 10 minutes. The blood that used to pool in the treated superficial vein is naturally redirected into the deep vein system. Patients experience almost immediate relief. Patients are encouraged to walk immediately after the procedure. Pain, which is seldom severe, is managed with anti-inflammatory medications such as ibuprofen. A follow-up visit within a week after the procedure will check for any blood clots and medication may be prescribed to manage a clot.
  • Ambulatory phlebectomy: This procedure to treat branch varicose veins can be performed in an office or as an outpatient. Patients are asked to stand for several minutes to allow the veins to fill, and the doctor marks the veins that are to be removed. Once the veins are marked and confirmed by the patient, numbing medication is injected into the skin along the course of the veins to be treated. Very small incisions, or nicks, in the skin are made and the veins are removed using a small hook. These incisions are so tiny that no stitches are needed. A dressing is placed on the leg, and patients are allowed to walk immediately after the procedure. Most patients do not require any pain medication, but when they do, anti-inflammatory medication is sufficient. Patients can return to work within a day or so, depending on the extent of the phlebectomy.
  • Sclerotherapy: This procedure to treat branch varicose veins can be performed in an office or as an outpatient.  Smaller veins are injected using a tiny needle containing a liquid that scleroses, or closes down, the vein. This treatment does not require any anesthesia or numbing medicine. Smaller veins (also known as spider veins) are best treated with this type of procedure.

Lifestyle Changes

Many patients with venous ulcers or who are at risk of developing a venous ulcer can reduce symptoms and lower their risk by quitting smoking, increasing exercise and eating a healthy, low-fat, low-sodium diet, and avoiding sitting and standing for long periods of time.

Complications

A venous ulcer can lead to a variety of serious health problems, including:

Loss of mobility: A venous ulcer can be painful and that can limit activity, which will make the condition worse.

Infection: Venous ulcers can easily become infected. If the infection is not treated, it can lead to blood poisoning or an infection of the bone.
