Abstract
Duplex scanning was used to study recurrent varicose veins in 244 limbs with previous high ligation of the long saphenous vein. The recurrent varicose veins were classified into two types according to the presence or absence of a residual long saphenous vein. Varicose veins with a residual long saphenous vein (type I) occurred in 168 limbs (68.9%). A residual long saphenous vein with an incompetent saphenofemoral junction was present in 125 limbs and one without any residual saphenofemoral junction in 43 limbs. Besides the presence of an incompetent long saphenous vein in this group, an incompetent short saphenous vein was detected in 26 limbs, incompetent perforating vein(s) in 45 limbs and incompetent deep veins in 26 limbs. Varicose veins without a residual long saphenous vein (type II) occurred in 76 limbs (31.1%). An incompetent short saphenous vein was demonstrated in 44 limbs, incompetent perforating vein(s) in 18 limbs and incompetent deep veins in 32 limbs. Of the total 244 limbs with recurrent varicose veins, long saphenous vein incompetence was involved in 168 (68.9%), short saphenous vein incompetence in 70 (28.7%), perforating vein incompetence in 63 (25.8%) and deep venous incompetence in 58 (235%). Although saphenofemoral junction incompetence was found to be the main source of recurrence, a segment of incompetent residual long saphenous vein, an incompetent short saphenous vein, perforating vein and deep venous system incompetence are other common sources of recurrence. A precise assessment to identify underlying venous incompetence is important for the management of recurrent varicose veins.
