Transthoracic aspiration biopsy of pulmonary and mediastinal lesions.

Thoracic aspiration biopsy (TAB) constitutes a useful technique in establishing a diagnosis in diseases of the lungs and mediastinum. Results obtained from 1046 fluoroscopically-guided TABs are presented with review of the most important aspects of the technique. Diagnostic accuracy in malignancy detection was 93.8% in lung lesions (n = 984) and 74.5% in mediastinal lesions (n = 62). Sensitivity was higher in peripheral than in central lesions (96% vs. 87%, respectively). Specificity was 100% in both groups. Sensitivity in lesions smaller than 2 cm was 70% and 94% in larger lesions. Aspiration biopsies performed with Chiba and Franseen needles showed a similar sensitivity (95%) higher than with other types of needles. A pneumothorax developed in 138 patients (13.2%). Only eight of these required the use of an endothoracic tube (0.8% of all biopsies).
