title: [Prevention of recurrent varicose veins after surgery caused by phenomenon of neovascularization].
abstract: The aim of study was to evaluate the effectiveness of surgical "barrier techniques" in prevention of phenomenon of inguinal neovascularization in patients with varicose veins of lower limbs. There were 68 patients (80 limbs) treated with flush ligation of saphenofemoral junction, stripping of great saphenous vein and avulsion of varicosities. Patients were divided in three groups: I (no "barrier techniques")--40 limbs; II (anatomical barrier)--20 limbs and III (synthetic barrier)--20 limbs. Duplex ultrasound was performed at interval of 24 months postoperatively. Signs of neovascularization were found more frequently in group I--22.5% of limbs vs 7.5% of limbs in patients with utilization of "barrier techniques". There were types B1, B2a and B2b of neovascularization only, according to Fischer classification. We conclude that use of a "barrier techniques", either anatomic or synthetic, is associated with a decreased incidence of neovascularization at the level of the saphenofemoral junction compared with a control group.
