Interventions

A randomised controlled prospective study of the use of a mechanical barrier to prevent neovascularisation recurrence of varicose veins following surgery. Two groups will be compared. - Group A: Complete surgical correction of venous reflux based on duplex ultrasound mapping and routine surgical techniques. - Group B: Treatment group: As for Group A plus surgical patch (PTFE) placed over the ligated saphenofemoral junction to obstruct new vessel formation. - Follow up of all patients (ultrasound
