Abstract
Retrograde femoral phlebography performed in the supine and erect positions are compared. In deep venous insufficiency, the contrast medium passes considerably farther down in the retrograde direction in examinations with the patient in the erect position. A comparison was made between ascending and retrograde techniques in order to find out what predictive value conventional ascending phlebography of the lower limb may have with regard to the function of the valves in the femoral vein. Layering of the contrast medium in the valvular sinus is a very reliable sign of valvular competence and was observed in 2/3 of the cases without deep venous insufficiency. This figure can be increased by a slight modification of the method of examination. Absence of layering does not necessarily indicate deep venous insufficiency.
