Duplex Ultrasound of Superficial Leg Veins in the Context of Saphenous Vein Sparing Surgery

Duplex ultrasound is the foundation to understanding venous haemodynamics as described in this book. That is the reason why the examination has to be mastered by at least one person in the team treating patients with varicose veins. In this chapter the identification of the different reflux sources, alone or in combination, refluxing pathways and re-entry points are described. Special attention will be given to the discrimination between the different shunt types after Franceschi. The typical outcome images after surgery, in case of failure as well as success, are discussed.
