In venous insufficiency states, venous blood escapes from its normal antegrade path of flow and refluxes backward down the veins into an already congested leg.

Venous insufficiency is neither uncommon nor benign. Treatment is aimed at ameliorating the symptoms and, whenever possible, at correcting the underlying abnormality. Graduated compression is the cornerstone of modern therapy. Deep system disease is often refractory to treatment, but superficial system disease can usually be treated by ablating the refluxing vessels. Refluxing superficial vessels can safely be removed or ablated without sequelae.
