Perioperative risk factors in surgical lung biopsy for the diagnosis of interstitial lung disease: a single-centre experience.

Prepared surgical lung biopsy for interstitial lung disease is feasible with reasonable morbidity. Higher NYHA class and elevated oxygen demand after the surgery could imply post-operative outcomes. Alternative diagnostic methods such as transbronchial biopsy or bronchoalveolar lavage should be considered prior to surgical lung biopsy especially in high-risk patients.
