To evaluate the applicability of Transcutaneous Pulmonary Fine-Needle Aspiration guided by ultrasonografy in the diagnosis of pulmonary lesions, including nodules, masses, inflamatory lesions and pleural effusions.
Transcutaneous Pulmonary Fine-Needle Aspiration guided by ultrasonografy was performed in 351 patients, from 1998 to 2002, with pulmonary lesions to obtain the diagnosis. Cytopathologic, histologic, microbiologic analysis were made.
The diagnosis was obtained by the method in 240 cases (68,4%). Were analysed 247 pleural effusions/pleural samples, 74 masses, 18 nodules, 5 consolidations, 4 necrotising lesions and 1 lymph node. Among the pleural effusions/pleural samples, the diagnosis were obtained by the method in 129 cases, being: 42 pneumonias, 26 neoplasms, 20 tuberculosis, 11 empyema, 4 hemothorax, 1 cryptococcosis, 1 leishmaniasis and 22 cases of pleural effusion caused by non-pulmonary diseases. Among the masses, diagnosis was obtained in 66: 53 neoplasia, 4 pneumonias, 2 aspergillosis, 2 cryptococcosis, 2 cavitary lesions, 1 tuberculosis. Among the nodules, diagnosis was obtained in 15 cases: neoplasias in 1; 3 tuberculosis, 1 pneumonia. Consolidations showed diagnosis in all cases: 3 tuberculosis, 1 cryptococcosis, 1 pneumonia. Cavitary lesions: diagnosis in all cases, being 3 infections, 1 neoplasm. There were 1 case of hemothorax and 5 (1,42%) cases of pneumothorax after the exam. None needed of tube thoracostomy.
Transcutaneous Pulmonary Fine-Needle Aspiration is useful in the diagnosis of pulmonary lesions and the risk of complications is very low.
It is an important instrument of diagnosis for malignant lesions, however, it is also useful to diagnosis of benign lesions. Moreover, it can avoid to submitt patient to more invasive methods to obtain the diagnosis of pulmonary diseases.
