Abstract OBJECTIVE: We observed long-term venous ultrasound and plethysmographic changes after varicose vein surgery, to determine factors that influence recurrence. METHODS AND MATERIALS: This observational sequential prospective study was carried out in an institutional referral center with day surgery. Subjects were 92 consecutive patients, ages 20 to 75 years, with symptomatic varicose veins in 127 limbs, who were able to complete regular assessment. Superficial varicose vein surgery included significant perforator vessels only, defined at preoperative duplex ultrasound scanning and air plethysmography. Similar follow-up assessments were performed at 3 weeks, 3 months, and 1, 3, and 5 years. RESULTS: At 3 weeks venous reflux but not muscle pump function was consistently improved in all limbs. However, inadequate surgery at the major junctions was clearly identified as contributing to recurrence of disease in 7.2\% of limbs. Recurrence of varicose veins occurred in 1 of 100 limbs (1\%) at the saphenofemoral junction and in 8 of 33 (25\%) limbs at the saphenopopliteal junction. However, after 3 years disease recurrence at these sites had increased to 23\% and 52\%, respectively. Incompetent perforator vessels increased progressively in number. Clinical recurrence was 47.1\%, and consistent with this was gradual deterioration in air plethysmographic measures of reflux, with physiologic recurrence (venous filling index, >2 mL/s) in 66\% at 5 years. Late recurrence was predicted in limbs with multiple sites of reflux preoperatively, venous filling index greater than 2 mL/s, and some other persistent abnormality at duplex scanning at 3 weeks. There was no recurrence in 40 limbs in which these factors were normal at at 3 weeks. However, 29 of 53 limbs with normal venous filling index after operative intervention had deteriorated at 3 years. CONCLUSION: Incomplete superficial surgery, in particular at the saphenofemoral and saphenopopliteal junctions, is a less frequent cause of recurrent disease, and neovascular reconnection and persistent abnormal venous function are the major contributors to disease recurrence.
