The function of the veins in the leg is to carry blood towards the heart. In some individuals, the veins fail to perform this function and the blood starts to reflux or flow backwards toward the feet and ankles. When this occurs, blood collects in the veins.
This is known as venous stasis.
Venous stasis can occur in any vein in the body but is most commonly observed in the legs. The reason for this is that humans are upright individuals. Prolonged standing and the pull of gravity make this disease process even worse.
Years of untreated venous stasis may lead to skin discoloration from the deposits of red blood cells within the skin. This can progress to create open sores known as venous stasis ulcers. The surgeons at Vegas Valley Vein Institute are experts in diagnosing and treating venous stasis.
