[Ascending varicose vein phlebitis--classification and therapy]. / Aszendierende Varikophlebitis--Klassifikation und Therapie.

Ascending varicophlebitis can cause pulmonary embolism by entering the deep venous system. Classification into four stages permits a differentiated therapeutic strategy: if the thrombus reaches or enters the deep venous system, immediate surgery consisting of crossectomy, resection of the saphenous vein, radical excision of all varicosed veins and ligature of insufficient perforating veins are indicated.
