WHAT IS DEEP VENOUS INSUFFICIENCY (DVI) also called CVI(CHRONIC VENOUS INSUFFICIENCY)
Damage to the Valves in the deep veins due to any reason, commonest being DVT(Deep Venous Thrombosis), leads to this condition, in which there is reflux of blood in the deep veins leading to a high venous pressure at the ankle.
VENOUS ULCERS, VENOUS ECZEMA, VENOUS SKIN CHANGES
When the venous system in the leg fails to work normally the pressure in the leg veins rises. This reduces the circulation in the lower leg particularly around the ankle leading to swelling, discomfort, skin changes and eventually ulceration. Varicose veins are the commonest cause for this.
ECZEMA AND SKIN CHANGES
A form of eczema can occur in the calf, sometimes over an area of varicosity.
The skin is red and itchy. Areas of the calf and around the ankle may develop a brown stain in the skin. The ankle area may be prone to swelling towards the end of the day.
Sometimes the entire lower leg feels tight and hard, and may look red and inflamed. This may be acute lipodermatosclerosis (LDS) due to the high venous pressure or an infection (cellulitis).
