[Phlebography for pre- and posttherapeutic control of fibrinolysis and thrombectomy (author's transl)].

The indications for fibrinolysis or thrombectomy when there is suspected fresh ilio-femoral venous thrombosis should be based on accurate phlebography at the earliest possible moment. Early posttherapeutic phlebography under standardised conditions should be used to control further treatment. Later examinations document the final outcome. Early phlebography, when treatment has been discontinued and has been unsuccessful, shows the so-called "Rischhalte phenomenon", which may be an indication for further thrombectomy. Seven cases are reported in which primary fibrinolysis with streptokinase was followed by thrombectomy with a Fogarty catheter. 3-Step-phlebography provides the essential information which governs treatment and demonstrates its results.
