Superficial thrombophlebitis is a frequent complication of varicose veins that occurs rarely on normal veins. In the latter case, it may be associated with thrombophilia, cancer or inflammatory disease. Superficial thrombophlebitis is rarely complicated by deep vein thrombosis through extension in the deep vein system. Therefore, depending of its localisation, a venous ultrasound is indicated to evaluate its extension. Treatment is based on elastic compression, non steroid anti-inflammatory drugs and mobilisation. If thrombophlebitis approaches the saphenous junction with the deep vein systems or involves perforans veins anticoagulant treatment is indicated.
