PURPOSE: To evaluate the rate of iatrogenic pneumothorax and the need for intervention with extrapleural autologous blood injection (EPABI) along with intraparenchymal autologous blood patch injection (IABPI) or IABPI-only in CT-guided percutaneous lung biopsy.
MATERIALS AND METHODS: One hundred and thirty-nine participants were referred for CT-guided percutaneous lung biopsy, and 81 were randomized into study (EPABI + IABPI, n = 40) and control (IABPI-only, n = 41) groups. In the study group, ~5 ml of autologous blood was injected into the extrapleural space before passing through the parietal and visceral pleura. The primary outcome was the incidence of pneumothorax in two cohorts within 2 weeks after the procedure.
RESULTS: In the per-protocol population, pneumothorax rates were 5.9% and 25.7% in the study and control groups, respectively. The difference between the two groups was -19.8% (95% CI: -36.3%, 3.32%) (p = 0.025). On the other hand, in the population with no intraprocedural deviations, pneumothorax rates were 3.2% and 17.2% in the study and control groups, respectively. The difference between the two groups was -14.0% (95% CI: -29.1%, 1.07%) (p = 0.083). In the control group, 3.45% of the cases required aspiration, while no intervention was required in the study group.
CONCLUSION: The EPABI application along with IABPI is a promising method to decrease the incidence of pneumothorax following CT-guided percutaneous lung biopsy.
