Long periods of reclining can cause pooling of blood in dependent areas. Vasovagal reactions also cause pooling of blood.
Venous pooling results in a decrease in cardiac output when a person goes from a lying to standing position. Venous pooling occurs when there is a buildup of blood in the veins of the legs that results due to gravitational pull when changing positions.

To prevent back flow of blood as the blood pressure in veins is greatly decreased compared to artieries
it does... in the lower legs, the muscle contractions help the venous valves to keep venous flow moving upwards, helping the blood move from the feet to the heart, preventing pooling of venous bloods and conditions like varicose veins. intercostal muscles help in breathing especially at times of high exertion like sprinting. the heart is a muscle itself: made of cardiac muscle. these are only some examples.
Though there could be multiple reasons behind this, and a real-time examination of the patient is required to make a proper diagnosis, a probable cause could be the compression of the venous network of the hip region involved in the surgery, due to which the venous return of the ankles and legs, which is primarily via the great saphenous vein draining into femoral vein, gets interrupted, causing pooling of blood and lymph in the lower limb, causing edema and hence swollen leg and ankle.
Venous ulcer are caused by venous insufficiency (improper functioning of venous valves).
The Substation which comes power from the power plant know as pooling substation.
These vessels are called venous sinuses. They act as blood reservoirs and are part of the venous or return portion of the cardiovascular system.
