title: Pneumothorax with fine-needle aspiration of thoracic lesions. Is spirometry a predictor?
abstract: 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.
