[Phlebography (author's transl)].

The article discusses the limitations of conclusive information supplied by different phlebographic methods. Particular attention is drawn to the insufficient staining properties, partly of the deep veins of the lower leg, the vena femoralis profunda and gastrocnemius veins. When assessing the course of acute phlebothromboses, conclusive information on the extent of thrombus formation is limited in complete obstruction of deep veins as well as in the reformation of thrombi in vessels which have already undergone post-thrombotic changes. Observation of the valvular function can supply essential information on the extent of fibrinolytic effects. Besides the conventional phlebographic techniques, the article also explains methods for the visualisation of rare angiomatoses with osseous involvement, using transosseous pelvic phlebography.
