Venous Reflux Disease

Venous System Anatomy

Venous Anatomy

The veins in the lower limbs are classified into two systems:

  • Superficial Veins (including saphenous)
  • Deep Veins

The two systems are connected by perforating veins that pass through the deep fascia

Three factors influence the return of blood back to the heart:

  • Respiration - the movement of the diaphragm creates a negative pressure that assists the return of blood from the legs to the heart
  • Vein Valves - healthy valves close, preventing blood from refluxing or pooling
  • Calf Muscle Pump - action of the calf muscle helps to force blood upward
