Understanding varicose ulcer causes can help people recognize the warning signs of chronic vein disease and seek appropriate medical care. Varicose ulcers, also called venous leg ulcers, can develop when damaged veins are unable to efficiently return blood from the legs to the heart. This may lead to increased pressure in the veins and changes in the surrounding skin and tissue.Book Dermatology Consults

Chronic venous insufficiency is one of the main conditions associated with venous ulcers. Faulty valves inside the veins can allow blood to flow backward and pool in the lower legs. Over time, this increased pressure may contribute to swelling, skin irritation, discoloration, and eventually an open sore that can be slow to heal.

Varicose veins themselves can be a sign of underlying venous insufficiency. Other factors that may contribute to venous ulcer development include prolonged standing or sitting, reduced mobility, obesity, previous blood clots, and a history of vein problems. Swelling and poor circulation can make the skin more vulnerable to injury and delay healing.

At USA Vein Clinics, patients with varicose veins or suspected venous ulcers can receive a comprehensive evaluation to identify the underlying cause. Duplex ultrasound may be used to assess blood flow and vein function. Treatment options can focus on improving venous circulation and addressing problematic veins.

If you notice a persistent sore, skin changes, swelling, or worsening leg discomfort, seeking evaluation from a vein specialist can help identify varicose ulcer causes and determine an appropriate treatment plan.
