[Evaluation of a new punction needle for transthoracic pulmonary biopsy]

A new percutaneous needle for pulmonary biopsy is described in this report, as well as its clinical applications--showing the different types of material that may be obtained--and the restrictions for its use. The results of using this biopsy needle were examined in 29 cases. Among these patients diagnoses of neoplastic processes--an accuracy of 82.75%--were established, being false or negative only 8.33% of the cases. In the rest of the patients, different kinds of pathological processes were examined (17.25 percent), which were mostly infectious cases. There was a low rate of clinically detectable complications (10.34%), all of them corresponding to pneumothorax.
