Venous Leg Ulcers

Venous leg ulcers: Pathophysiology and Classification

“Venous leg ulcers (VLUs) are defined as open lesions between the knee and ankle joint that occur in the presence of venous disease. They are the most common cause of leg ulcers, accounting for 60-80% of them. The prevalence of VLUs is between 0.18% and 1%. Over the age of 65, the prevalence increases to 4%. On an average 33-60% of these ulcers persist for more than 6 weeks and are therefore referred to as chronic VLUs. These ulcers represent the most advanced form of chronic venous disorders like varicose veins and lipodermatosclerosis.”
