Recurrence after varicose vein surgery: a prospective long-term clinical study with duplex ultrasound scanning and air plethysmography.

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.
