“…When looking into this further, 76% of the patients with delayed pneumothoraces only had their first radiographs three hours or later after the procedure and it is possible that a large proportion of the pneumothoraces could have been detected earlier if imaging had been performed earlier. Our results are comparable to those of Vell et al ., 14 where the majority (83%) of post‐biopsy pneumothoraces were diagnosed during the procedure.…”

IntroductionIdentify the risk factors for delayed pneumothorax after lung biopsy.MethodsA retrospective study of 355 CT‐guided lung biopsies was performed at Fiona Stanley Hospital, Western Australia over 42 months. A comprehensive range of patient, lesion and procedural variables were recorded. All post‐procedural complications including time, size of pneumothorax and post‐biopsy radiographs were reviewed. Lasso logistic regression model was utilised to determine factors predicting patient complications.ResultsA total of 167 patients (47%) developed a pneumothorax, in which 34% were significant, requiring longer observation or drain insertion. The majority of pneumothoraces occurred within the first hour (86%), with 90% detected at the time of the procedure. Then, 12% were detected more than 3 h post‐procedure, of which 8 patients (5%) had a significant delayed pneumothorax. Factors increasing the likelihood of significant pneumothorax include the length of lung traversed, smaller nodule size, surrounding emphysema, increased age and lateral patient position with the lesion in the non‐dependent aspect. Increasing patient age, longer length of lung traversed and smaller nodule diameter increase the risk of delayed onset of pneumothorax (more than 3 h).ConclusionThe results of this study align with other studies indicating it is safe to discharge stable patients within an hour post‐lung biopsy. However, specific risk factors, including age, small lesion size and deep lesions, may identify patients who could benefit from a longer observation period.
