To assess the value of spirometry for predicting the risk of pneumothorax (PTX) following percutaneous fine needle aspiration (FNA) of thoracic lesions, we examined retrospectively the incidence of PTX in 89 FNA and associated spirometry. Spirometry results were classified as normal, obstructed, or restrictive. Overall, the PTX rate was 20 percent. When the PTX occurrence was analyzed based on our spirometry classification, no significant difference was found between the groups. A PTX occurred in 27.8 percent of the FNA performed in patients with normal spirometry. On further analysis of specific spirometry measurements (FEV1, FVC, FEV1 percent predicted, and FEV1/FVC) and incidence of PTX, no significant correlation in PTX rates was found. These data suggest that the FNA pneumothorax is not correlated with lung function as measured by routine spirometry.
为评估肺功能测定对预测经皮细针穿刺抽吸（FNA）胸部病变后气胸（PTX）风险的价值，我们回顾性研究了89例FNA及相关肺功能测定患者的PTX发生率。肺功能测定结果分为正常、阻塞性或限制性。总体而言，PTX发生率为20%。当根据我们的肺功能测定分类分析PTX发生情况时，各组之间未发现显著差异。在肺功能正常的患者中进行的FNA，27.8%发生了PTX。进一步分析特定的肺功能测定指标（第一秒用力呼气容积（FEV1）、用力肺活量（FVC）、预测FEV1百分比和FEV1/FVC）与PTX发生率后，未发现PTX发生率之间存在显著相关性。这些数据表明，FNA气胸与常规肺功能测定所测的肺功能无关。
