[From phlebothrombosis to the postthrombotic syndrome].

The same pathomechanism causes both thrombosis of the superficial and deep veins. For practical purposes one may separate phlebothrombosis of bed-patients and that of out-patients. Superficial phlebothrombosis and thrombophlebitis of the out-patients heal in shorter time by compression according to Heinrich Fisher. Patients should not be immobilized. Phlebothrombosis of the bed-patient should be reserved to clinical therapy including fibrinolysis, thrombectomy and anticoagulants. The post-thrombotic syndrome is treated usually by the practitioner. Treatment first has to activate drainage by lymphatic vessels and by paravenous tissue. Correct compression will improve circulation of fluid from tissue to capillaries. When balance is achieved, further physical measurements will be of help.
