Chronic Venous Insufficiency (CVI): Its Causes & Treatment

Chronic Venous Insufficiency (CVI) is a condition where veins do not efficiently return blood from the limbs back to the heart. It may occur following excessive blood clotting (such as deep vein thrombosis) and leg veins inflammation. It can also result from the failure of the vein valves to close properly and to hold blood against gravity. In this condition, sluggish movement of blood from the veins result in swollen legs, crampings and the feelings of dull achiness and/or heaviness ("heavy leg" or "tired leg" syndrome).

CVI is a common problem in the United States - it is estimated that up to approximately 5% of Americans or 15 million people have chronic venous insufficiency. CVI affects mostly older people, especially older women.


What are the Causes of Chronic Venous Insufficiency?

In a normal leg vein, the flow of blood from the legs to the heart is facilitated by a series of valves on the inner vein walls. These valves open to permit the flow of blood to the heart, but close to prevent blood from flowing back to the lower limbs.

Failure of these vein valves to close properly can cause blood to leak backward into the leg, in a condition called venous insufficiency or chronic venous insufficiency.

There are many conditions that lead to vein valve failure, including blood clots in the deep vein (deep vein thrombosis) and varicose vein. Risk factors of CVI includes genetics or the inherited tendency of vein valves to fail, old age, extreme inactivity, obesity, diabetes mellitus, and heart disease. Hormonal changes, such as those that occur during pregnancy, certain forms of vein cancer, as well as injury can also lead to CVI.


What are the Symptoms of Chronic Venous Insufficiency?

The symptoms of chronic venous insufficiency include:

  • Swollen feet, ankles, and calves
  • Dull aching and pain, especially after a prolonged period of standing
  • The feeling of "heaviness" or tiredness of the leg (leg fatigue)
  • Burning sensation
  • Cramping or charley horse
  • Itching
  • Flaking of the skin
  • Skin discoloration and darkening
  • Leg skin that looks and feels leathery
  • Spider veins, reticular varicosities, and varicose veins
  • Ulcers or sores, in some advanced cases of CVI

The first sign of CVI is usually swelling in the leg and ankle. This swelling occurs because pooled blood cause abnormally high pressure in the veins. As the pressure increases, vein and arteries in the lower limbs may leak tiny drops of plasma, causing a pale yellow discoloration. Capillaries may also break, giving the skin a localized reddish brown discoloration. If scratched or bumped, discolored skin can break, often resulting in ulcers or sores, which subsequently can become infected.

In some instances, stasis or pooled blood can also cause a symptom of Restless Leg Syndrome, where the person has an irresistible urge to move the leg, especially at night.

As listed above, venous insufficiency can also result in enlarged veins, either small (spider veins), medium (reticular varicosities), or large (varicose veins).


Treatments of Chronic Venous Insufficiency

Treatment of chronic venous insufficiency includes:

Elevating Your Legs and Peforming Leg Exercises

For mild and early cases of chronic venous insufficiency, elevating your feet above your heart level whenever you are sitting or lying down can help the pooled blood to drain. Elevate your leg for 15 to 20 minutes about 4 times daily.

Unless you are obese, or suffering from heart disease and hiatal hernia, you can also elevate the foot of your bed approximately 9 inches to help blood to drain during the night.

Avoid long periods of sitting or standing. If you are taking long flights, remember to flex and extend your legs, feet, and ankles about 10 times every 30 minutes to facilitate blood flow in the veins.

   

Compression Stockings

Compression or elastic stockings work by squeezing the vein and helping to keep the blod flowing away from the extremities of the limb and back to the heart.

These special stockings have varying or graduated pressure along the height of the leg, with tighter fit at the bottom of the leg. This is because the ankle and calf veins are under greater pressure than the rest of the leg veins and need more support.

Stockings do tend to give quick relief from chronic venous insufficiency symptoms. However, they have the following drawbacks:

  • It does not cure chronic venous insufficiency, and the symptoms may get progressively worse over time.
  • If improperly fitted, elastic stockings can cut off circulation to the lower legs.
  • These stockings need to be worn all the time and can get uncomfortable throughout the day.
  • Specially fitted stockings can be expensive and need to be replaced about four times per year.
   

Prescription Cream

To alleviate the itching and cracking of the skin, your doctor may prescribe an anti-itch cream containing hydrocortisone and moisturizer. To prevent infection, he may also prescribe a zinc oxide cream or an anti-fungal cream.

For skin sores, compression bandages can be applied to protect the skin and promote blood flow. For infected ulcers and cellulitis, antibiotics are prescribed.

   

Vein Surgery

Depending on the position and depth of the vein, various forms of vein surgeries can be performed to unblock blood clots that form in the vein, bypass faulty veins, as well as to repair faulty vein valves.

   

Herbal Supplements

Studies have shown that various herbal supplements can be used to naturally treat chronic venous insufficiency. These herbs include:

Japanese pagoda tree (Sophora japonica)

Studies have shown that Japanese pagoda tree extracts, with the active ingredients of rutin bioflavonoids, can improve vein wall tone and strength, increase microcirculation, reduce swelling, improve elasticity, and fix vein permeability. Numerous clinical studies, involving more than 2,000 patients, have shown that Japanese pagoda tree extract can provide substantial relief from the swelling, aching, leg pains, and other discomforts of CVI.

Horse chesnut (Aesculus hippocastanum)

Horse chestnut has been used for many decades as an herbal preparation for various vein conditions. It has been shown to reduce inflammation and improve the vein wall tone to facilitate blood flow back to the heart. It is thought to fix microscopic leaks in tiny veins and capillaries, as well as reinforce the strength of the vein walls and promote their elasticity.

A 1996 study involving 240 patients showed that horse chestnut extract is just as effective as elastic stocking in providing relief from the swelling and pain of varicose veins and chronic venous insufficiency.

Butcher's broom (Ruscus aculeatus)

Butcher's broom extract has been used for many years as a traditional medicine for treating vein disorders. In the 1950s, studies on Butcher's broom discovered that it can strengthen and tone veins, as well as lessening swelling and inflammation.

In treating chronic venous insufficiency as well as varicose veins, butcher's broom has been found to relieve not only leg pains, but also swelling, itching, numbness, cramping, and the "heavy" sensation in the leg.
