Recurrent varicose veins may result from inadequate assessment or inadequate surgery. In this study, 110 consecutive patients (165 limbs) were assessed pre‐operatively for the presence or absence of reflux at the saphenofcmoral (SF) and saphenopopliteal (SP) junctions by clinical assessment and by Doppler ultrasound. The pre‐operative results where then compared with findings at the time of surgery. Doppler ultrasound as a means of predicting SF and SP incompetence was superior to clinical assessment. Doppler ultrasound detected 100% (two false positives) of incompetent SF junctions, and 100% (six false positives) of incompetent SP junctions, compared to the clinical detection of 72% (no false positives) and 64% (five false positives), respectively. Short saphenous venography was performed in 36 limbs in which SP reflux was suspected on clinical assessment and/or by Doppler ultrasound. It proved valuable in demonstrating the level and mode of termination of the short saphenous vein. This guided the placement of the skin incision.
