[Surgery of lung metastases in childhood (author's transl)].

Over the past 10 years 18 patients have been operated upon (sometimes repeatedly) because of pulmonary metastases. The primary tumour with pulmonary secondaries was usually an osteosarcoma or a Wilm's tumour. The indication for surgery and the result of treatment are discussed. The pre-operative diagnosis is helped considerably by ventilatory and perfusion isotope studies.
