The word lipodermatosclerosis is very descriptive of the condition.
“Lipo” means fat, “Dermato” means skin, and “Sclerosis” means hardening. Hence, lipodermatosclerosis literally means a hardening of the skin and underlying fat. These changes occur due to inflammation.
Lipodermatosclerosis is a medical condition that affects the lower legs between ankle and calf muscles. It is basically an inflammation of the skin and subcutaneous tissues of the lower leg.
The skin becomes discoloured due to inflammation. It can be pink or red when there is active inflammation, or a light or dark brown colour (haemosiderin) if the condition has been present for longer.
The underlying tissue becomes harder due to the inflammation.
The most common cause of lipodermatosclerosis is venous reflux due to varicose veins, or “hidden varicose veins.”
The constant reflux of blood falling down varicose veins, or hidden varicose veins, causes inflammation just above the ankle. If a reflux is not treated (i.e., the varicose veins are not treated), then over time the inflammation increases. Slowly, this increases the damage. The skin and subcutaneous fat around the ankle.
This can manifest in several different ways, but one of the commonest is lipodermatosclerosis.
The best way to treat lipodermatosclerosis (LDS) is to treat the underlying venous reflux. This means treatment of the varicose veins, or “hidden varicose veins.” These may be refluxing saphenous veins, incompetent perforating veins, or pelvic veins.
It is essential to have a high-resolution venous duplex ultrasound scan performed by a properly trained vascular technologist who looks for all of the different causes for venous reflux.
Treatment is usually by endovenous surgery to the saphenous veins and Ultrasound Guided Foam Sclerotherapy for incompetent perforators.
