As has been mentioned in the chapter describing the post-thrombotic syndrome, incompetence of the venous valves in the femoral and popliteal veins is the cause of congestion and edema, resulting in dermatitis, induration and ulcers in the ankle region and other portions of the lower leg. Incompetence of the valves of calf veins may lead to “failure of the peroneal muscle pump”, which is of considerable importance as a causal factor of the complex of symptoms, comprised by the term “post-thrombotic syndrome”.
