[X-ray controlled percutaneous needle aspiration biopsy of the lungs (author's transl)].

Between 1976 and 1978 percutaneous needle aspiration biopsies of 120 pulmonary and pleural lesions were performed. Cytologic examination of malignant and benign lesions was correct in 64% of the cases, false negative results were obtained in 19%. Complications included: pneumothorax in 21 patients (11 requiring chest tube placement); insignificant hemothorax in 5 and hemoptysis in 1. Needle biopsy of intrathoracic lesions proved to be technically simple and relatively safe. This procedure allows early diagnosis of malignant lung tumours which may improve long term prognosis.
