In venous insufficiency, the valves in the veins have become damaged. Theses valves normally keep blood flowing toward the heart. But damaged valves allow some blood to flow backward. This causes the veins to become overfilled. Fluid seeps out of the engorged veins into surrounding tissues. This results in tissue breakdown and venous skin ulcers.
