PURPOSETo assess the effectiveness and safety of autologous intraparenchymal blood patch (IBP) application in reducing the frequency of pneumothorax (PTX) after percutaneous transthoracic pulmonary core needle biopsy.METHODSThe records of patients who underwent the transthoracic pulmonary core needle biopsy procedure under CT guidance between January 2015 and October 2018 were screened retrospectively. Patients whose traversed pulmonary parenchymal length was ≥20 mm during biopsy were included in the study irrespective of lesion size. The IBP procedure was made a department policy in November 2017; patients who underwent biopsy after this date comprised the IBP group, while those who underwent the procedure before this date comprised the control group. IBP recipients received 2–5 mL of autologous blood injection to the needle tract. Demographic data, procedural reports, tomography images, and the follow-up records of patients were assessed.RESULTSA total of 262 patients were included in the study. Of the 91 patients that received an IBP, PTX developed in 13 (14.1%), with 7 (7.7%) requiring a thoracic tube. Of the 171 patients who did not receive an IBP, PTX developed in 45 (26.3%), with 19 (11.1%) requiring a thoracic tube. Patients who received an autologous IBP showed a significantly lower rate of PTX development versus those who did not (P = 0.01). Similarly, a significantly lower number of patients who received the blood patch required chest tube placement (P = 0.015).CONCLUSIONAutologous IBP is a safe, inexpensive and easy to use method that reduces the rate of PTX development and thoracic tube application after percutaneous core needle biopsies of the lung.
