An analysis of 617 percutaneous intrathoracic aspiration biopsies (PIAB) performed on 587 patients with pulmonary and mediastinal lesions between 1954 and 1985 are presented. The effectiveness of the procedure between 1954 and 1980 and between 1981 and 1985 with a positivity of 71.6% and 84.9%, respectively, was compared. These results are statistically significant and reflect improvement in the technique employed. A greater positivity was found where the lesion measured 2 to 3 cm in diameter. Complications for this series were 7.8%. In diffuse infiltrating lesions, the positivity is less than that obtained for the whole series, and the risk of developing a pneumothorax is greater. The false-negative cases include those in which an inadequate sample was obtained for diagnosis (13.9% of the total series) and samples containing elements of the chest wall or blood (5.2%).
本文呈现了对1954年至1985年间587例患有肺部和纵隔病变的患者进行的617次经皮胸腔穿刺活检（PIAB）的分析。比较了1954年至1980年以及1981年至1985年间该操作的有效性，阳性率分别为71.6%和84.9%。这些结果具有统计学意义，反映了所采用技术的改进。发现直径为2至3厘米的病变阳性率更高。该系列的并发症发生率为7.8%。在弥漫性浸润性病变中，阳性率低于整个系列的阳性率，发生气胸的风险更大。假阴性病例包括因获取的样本不足以进行诊断的情况（占总系列的13.9%）以及含有胸壁或血液成分的样本（5.2%）。
