Recurrent Varicose Veins after Short Saphenous Vein Surgery: A Duplex Ultrasound Study

Recurrent venous reflux in the popliteal fossa of patients with recurrent varicose veins following short saphenous vein surgery was assessed in 70 limbs using a duplex scanner. Incompetence of the short saphenous vein was found to be the main source (61%) of venous reflux in the popliteal fossa (43/70). The recurrence or persistence of the short saphenous vein was subdivided into four types: an intact saphenopopliteal junction, as well as an intact short saphenous vein in 20 limbs (type I); varicosities in the popliteal fossa communicating with a short saphenous vein stump in 11 limbs (type II); a residual short saphenous vein communicating with the popliteal vein via a tortuous recurrent vein in eight limbs (type III); and a segment of residual short saphenous vein with no communication with the popliteal vein in four limbs (type IV). Incompetence of a gastrocnemius vein was involved in 24 cases (34%), an incompetent popliteal area vein in one (1.4%), popliteal vein incompetence in 15 (21%), and popliteal fossa varicosities communicating with the long saphenous system in two (3%). Of 12 limbs tested pre- and postoperatively, a high termination of the short saphenous vein was demo
