[Pulmonary embolism in the elderly patient (author's transl)].
Pulmonary embolism has a high incidence in old patients and is often not recognized. In most cases the embolism is of unknown origin, although the deep venous system of the lower extremities is involved in almost 95%. The diagnostic procedure consists of evaluation of clinical symptoms and findings. ECG and chest X-ray are often not conclusive. Confirmation of the diagnosis is possible by ventilation-perfusion scanning of the lung. Pulmonary angiography is of no value in the elderly patient, because of the lack of consequences. Besides local therapy of a thrombosis, therapy consists of administration of heparin, while oral anticoagulation should be used only with precaution. The efficacy of platelet aggregation inhibiting substances remains to be determined. The main point are prophylactic measures in patients with risk factors or in high risk situation.
