Saphenous vein reflux without incompetence at the saphenofemoral junction

Abstract

Abstract Duplex ultrasonography was used to assess patients with primary varicose veins to determine whether varicosities of the long saphenous vein (LSV) occurred without saphenofemoral junction (SFJ) incompetence. Some 167 consecutive patients with the clinical diagnosis of primary varicose veins were investigated. Of 190 limbs with LSV reflux 63 had no SFJ incompetence, of which only five had incompetent perforators; these were midthigh perforators in two limbs and medial calf perforators in three. LSV reflux, often occurs in the presence of a competent SFJ. This indicates that, in such circumstances, saphenofemoral ligation alone is unlikely to control varices associated with LSV reflux. It also suggests that the development of primary varicose veins may be an ascending rather than a descending phenomenon.
