A specially designed three-pronged aspiration needle is described. It was used in 166 percutaneous lung biopsies in 151 patients. A correct diagnosis was obtained in 141 patients (93.3%). Only minor complications were seen, including pneumothorax (7.8%) and pulmonary hemorrhage with hemoptysis (2.4 percent).
The results of 166 lung biopsy procedures performed on 151 patients using a specially designed cutting aspiration needle are summarized. Excellent tissue cores and fragments of tissue were obtained providing a pathologic diagnosis in 85.5% of attempts. A correspondingly low overall complication rate of 12.7% was obtained.
Complete myelography using metrizamide and a lumbar puncture is described with special emphasis on the cervical region. Good visualization of the cervical region was obtained in 19 of 20 patients using 10-12 ml and iodine concentrations of 250 mg/ml without special techniques or precautions. Possible explanations of failure to visualize the complete subarachnoid space are discussed.
