Chronic Venous Insufficiency
by Editorial Staff And Contributors
Chronic venous insufficiency is a problem with how your veins are working. Veins collect blood from the body to bring back to the heart. The veins have one-way valves throughout the blood vessel that keep the blood moving in the right direction, toward the heart. When these valves do not close properly, blood can leak backwards. This can cause a back up of blood in the veins especially areas of the body where veins must work against gravity like the legs.
Chronic venous insufficiency is caused by higher than normal pressure in the veins and damage to the valves that keep blood flowing toward the heart. It can be caused by blood clots or swelling and inflammation of the veins. Blood clots in the legs can damage the valves in the veins. When people get chronic venous insufficiency after a blood clot, it may be referred to as post-thrombotic syndrome. When it occurs after phlebitis, it may be referred to as post-phlebitic syndrome.
Causes of chronic venous insufficiency include:
Risk Factors TOP
Chronic venous insufficiency is more common in women and in people aged 50 years and older. Other factors that may increase your chance of getting chronic venous insufficiency include:
Chronic venous insufficiency may cause:
You will be asked about your symptoms and medical history. A physical exam will be done.
Images may be taken of your bodily structures. This can be done with:
Treatment is aimed at maintaining blood flow and preventing it from pooling. Treatment involves the following:
Improving Blood Flow
Special elastic stockings that squeeze the veins in the legs may be advised. They will help keep the blood from pooling. You may also be advised to raise your feet and legs above the level of your heart while resting or sleeping. You may need to do this several times a day.
Therapeutic massage of the lower legs may be advised to reduce discomfort and to drain fluid buildup.
Walking and specific exercises for your legs and feet may help. Long periods of sitting and standing should be avoided.
Skin Care TOP
Mineral bath therapy may help to improve skin redness. Bandages or antibiotic cream may be advised to help prevent skin infection. Wearing compression stockings may also promote healing.
Sclerotherapy or Ablation TOP
Sclerotherapy may be advised. It involves injecting a caustic material into the affected veins. Scar tissue fills the veins. The blood is rerouted through functioning veins. Ablation is another procedure used to treat the veins. A tiny electrode is inserted into the affected vein. Electricity scars the vein and blocks it off.
With both treatments, the body will resorb the nonfunctional vein over time.
Surgery is reserved for the few cases that do not respond to conservative treatment. The type of surgery will depend on the cause of the condition and the results of testing. Some possibilities include:
