Chronic Venous Insufficiency (CVI) is a medical condition which valves present in the veins in the legs don’t function properly. This causes blood to pool in the legs, which can cause pain, swelling (edema), skin discoloration, and potentially open sores (ulcers).
There are various causes of CVI, including obesity, smoking, lack of exercise, sitting or standing for long periods of time, pregnancy, and blood clots (deep vein thromboses). These practices and elements can cause higher pressure in the veins in the legs.
When pressure is raised in the veins, the valves inside the veins intended to ensure blood flows back to the heart can become stressed or malfunction. This can cause CVI.
Left untreated, CVI can cause the formation of ulcers on the legs known as venous ulcers. CVI can also cause venous stasis (slow blood flow in the veins), skin thickening, cellulitis, and various skin conditions.
Symptoms of CVI include:
- Varicose veins
- Changes in skin pigmentation
- Chronic swelling of the legs, ankles, and feet
- Venous ulceration
How Our Devices Help Treat Lymphedema
Sequential Compression Devices are designed to deliver pressure to the legs through air compression. The devices connect to garments worn on the legs.
The compression squeezes the legs to eliminate swelling and increase blood flow. The increase of blood flow can prevent pooling and therefore help the patient recover from CVI and avoid ulcers.
