[Diagnostic problems of pulmonary embolism].

There is no pathognomonic sign for pulmonary embolism. The diagnosis must be made from the combination of anamnestic, clinical and paraclinical parameters. An essential purpose of the paper is the demonstration of the valency of these parameters. The clinical proof of the origin of embolism facilitates the establishment of the diagnosis, is, however, often not possible. The pulmonary embolism as well as the origin of embolism are most certainly to be proved by angiographic investigation methods. On account of the vital endangering by relapses as well as the necessity of a different and extensive therapy the securing of the diagnosis is necessary.
