Perilesional emphysema as a predictor of risk of complications from computed tomography-guided transthoracic lung biopsy.

Purpose: This study evaluated whether or not patterns of emphysema and their qualitative and quantitative severity can predict the risk of complications with post-computed tomography (CT)-guided transthoracic lung biopsy (TTLB).

Materials And Methods: Three hundred and ninety-seven patients who underwent CT-guided TTLB in 2010-2018 were retrospectively reviewed. The severity of emphysema and presence of perilesional emphysema were assessed visually using the Fleischner Society classification.
