Overview:
Chronic venous insufficiency (CVI) is a condition that occurs when the venous wall and/or valves in the leg veins are not working effectively, making it difficult for blood to return to the heart from the legs. CVI causes blood to “pool” or collect in these veins, and this pooling is called stasis.
Contributing Factors:
People with chronic venous insufficiency may have:
- Skin color changes around the ankles
- Varicose veins on the surface of the skin
- In the ankles of overweight patients, acute fat necrosis can occur.
- Restless legs
- Ulcers on the legs and ankles
- Thickening and hardening of the skin on the legs and ankles (Lipodermatosclerosis)
Symptoms:
Symptoms include varicose veins, swelling, or skin color changes on the affected leg. If the condition progresses, leg ulcers can form.
- Aching or heaviness in the legs
- Cramping in the legs at night or while resting
- Itching, tingling, or swelling
- Pain that gets better while standing
