ABSTRACT
Objective - to evaluate the effectiveness of surgical treatment of varicothrombophlebitis complicated by transfascial thrombosis. The results of examination and treatment of 45 patients with varicothrombophlebitis of the great saphenous vein complicated by transfascial thrombosis. The indications for surgical prophylaxis of pulmonary embolism in transfascial thrombosis in the basin of the great saphenous vein have been substantiated. In the postoperative period, all patients with transfascial thrombosis, regardless of the radical nature of the surgical intervention, were offered to prescribe treatment as in deep vein thrombosis. The introduction of active surgical tactics in transfascial thrombosis allows for effective prevention of pulmonary embolism. In varicothrombophlebitis complicated by transfascial thrombosis, thrombectomy with further prevention of recurrence of the disease and pulmonary embolism should be considered the main standard of treatment. For perforating vein thrombosis, subfascial thrombectomy followed by perforating ligation should be performed. All patients with transfascial thrombosis, regardless of the volume of surgery, should be treated as for deep vein thrombosis.
