Rationale and Efficacy of the Substitute "Valve" Operation by Technique II in Deep Venous Insufficiency of the Lower Limb

The substitute "valve" operation by Technique II designed to overcome reflux in the popliteal vein was performed on 105 patients (119 limbs) with deep venous incompetence of the lower limb. There was a five-year follow-up on 101 of them (115 limbs) after operation by Technique II. Results were assessed clinically, by Doppler ultrasound, by venous pressure measurements, and by phlebography. Clinical improvement in 108 of 115 limbs was associated with a decrease in ambulatory venous pressure and prolongation of refilling time with interruption of the popliteal reflux by Doppler (96 limbs) and with phlebographic evidence of a functioning substitute "valve."
