Chronic venous disease progression and modification of predisposing factors.

Aim: This study evaluated long-term characteristics of chronic venous disease (CVD) progression and its correlation with the modification of specific risk factors.

Methods: The contralateral limb of 73 patients (95% women; mean age, 48 +/- 12 years) undergoing varicose vein surgery was prospectively evaluated using physical and color duplex examination and classified by CEAP. After 5 years of follow-up, development of new sites of reflux among the contralateral, preoperatively asymptomatic limbs and modification of predisposing factors, including prolonged orthostatism, obesity, estrogen therapy (ET), multiparity, and elastic stockings use (ESU), were assessed.
