Abstract

Venous diseases of the lower limbs are extremely complex due to wide variability of veins on the surface of the skin. It is important to understand the normal anatomy and physiology of veins of lower limbs with regard to management of pathology of leg veins. Venous hypertension leads to alterations in vein wall, valve incompetence and chronic venous insufficiency. The superficial compartment comprises of three tributaries namely, greater saphenous vein (GSV), short saphenous vein (SSV) and lateral subdermic venous system (LSVS) of Albanese. This chapter covers the physiology of venous system of lower limbs, and venous pathophysiology. Venous pressure is largely determined by gravity. When the body is horizontal, venous pressure in the lower extremity is equal to that of lower abdomen. As the body becomes upright, the pressure in the lower limbs increases dramatically.
