Early use of autologous blood patch pleurodesis in children is successful in resolving persistent air leaks

Introduction: Epidural blood patches (EBPs) are rarely performed at the high-level cervical levels. The aim of the study was to investigate the imaging features, safety, and effectiveness of CT-guided percutaneous EBPs for high-level cervical cerebrospinal fluid (CSF) leakage. Methods: Twenty-five patients with spontaneous high-level (C1–C3) CSF leakage on MRI and CT imaging, including 2 patients with intracranial epidural hematoma caused by CSF, were treated with EBP. Two needles were inserted into the C1–3 bilateral epidural space. The needle location was confirmed by injection of both 3–5mL sterile air and a diluted iodinated contrast agent to delineate its spatial diffusion. The patient’s blood 11.1 ± 3.1 mL was slowly injected to make a patch; the distribution in epidural space was monitored with intermittent CT scanning. Results: The typical manifestation of CSF leakage was the high signal outside the C1–3 cervical dura on MR T2W fat inhibition images and low density in cervical muscle space on CT images. Twenty patients suffered from headaches and were able to sit and walk 24 h after the operation. Four patients, with partial relief of headache and a small but persistent CSF leakage, were re-treated with EBS. One patient underwent a third operation because of a persistent CSF leakage on MRI. Conclusions: Imaging of water at the surrounding epidural space of high cervical level is a typical feature of dural rupture on both MRI and CT. CT-guided EBP is safe and efficient for the high-level cervical CSF leakage, especially for cases in which conservative treatments failed.

Abstract Background Air leak is the most common complication after lung resection and leads to increased length of hospital (LOH) stay or patient discharge with a chest tube. Management by autologous blood patch pleurodesis (ABPP) is controversial because few studies exist, and the technique has yet to be standardized. Methods We retrospectively reviewed patients undergoing ABPP for prolonged air leak (PAL) following lobectomy in three centers, between January 2014 and December 2019. They were divided into two groups: Group A, 120 mL of blood infused; Group B, 60 mL. Propensity score-matched (PSM) analysis was performed, and 23 patients were included in each group. Numbers and success rates of blood patch, time to cessation of air leak, time to chest tube removal, reoperation, LOH, and complications were examined. Univariate and multivariate analysis of variables associated with an increased risk of air leak was performed. Results After the PSM, 120 mL of blood is statistically significant in reducing the number of days before chest tube removal after ABPP (2.78 vs. 4.35), LOH after ABPP (3.78 vs. 10.00), and LOH (8.78 vs. 15.17). Complications (0 vs. 4) and hours until air leak cessation (6.83 vs. 3.91, range 1–13) after ABPP were also statistically different (p < 0.05). Air leaks that persisted for up to 13 hours required another ABPP. No patient had re-operation or long-term complications related to pleurodesis. Conclusion In our experience, 120 mL is the optimal amount of blood and the procedure can be repeated every 24 hours with the chest tube clamped.
