Understanding Venous Disease: Venous Ulcers
Understanding Venous Disease: Venous Ulcers
A venous leg ulcer is the most severe form of chronic venous insufficiency. This is referred to as a ‘venous leg ulcer.’ Venous ulcers of the leg make up 70% of all chronic leg wounds. Therefore, a venous leg ulcer is much more common than a diabetic or arterial ulcer. It is caused by long-standing pressure within the leg veins, resulting from 1) venous reflux through faulty valves, 2) a blockage within the deep veins or 3) from the inability to use the calf muscles or a combination. Venous reflux is the most common cause of a venous leg ulcer. The increased pressure within the leg veins (we call this venous hypertension) causes an inflammatory response. Inflammation then causes changes in the skin, usually around the ankles (this is where pressure is the greatest). The inflammatory process will cause the skin around the ankles to become brown or discolored, and eventually, the skin will break open. The leg wound can be healed by treating the underlying vein condition. Venous ulcers on the leg can also be prevented by early intervention with non-invasive procedures. If you have signs of chronic venous insufficiency (such as skin discoloration around the ankles) you should address your underlying vein condition to prevent the skin from breaking open.

Venous leg ulcers make up 70% of all chronic leg wounds. They usually occur in the inner ankle or outer ankle locations.
The treatment of venous leg ulcers is to correct the underlying problem: the faulty veins. Treatment of the underlying non-functional veins will reduce pressure from venous hypertension, allowing the wound to heal. There are a number of non-surgical treatment options that can accomplish this including foam sclerotherapy and endovenous ablation, depending on the affected veins. To determine if your leg wound is related to a vein problem or for treatment options, call us for more information.
