Veins carry the deoxygenated blood to the heart. Healthy leg veins have valves that keep blood flowing to the heart. Chronic venous insufficiency develops when the valves become incompetent and allow blood to flow backward and pool in the lower leg veins. If left untreated, symptoms can worsen over time sometimes causing leg ulcers to develop.
Venous insufficiency doppler is used to measure reflux in the leg and assess for venous insufficiency or incompetent veins. Also to evaluate for blood clots in legs (ie. Deep Vein Thrombosis (DVT). Symptoms include swelling or pain in the legs, skin discoloration or superficial leg ulcers, and spider or varicose veins.
