Novel Use of Extrapleural Autologous Blood Injection in CT-guided Percutaneous Lung Biopsy

If the patient was assigned to EPABI plus IABPI, while the extrapleural space was reached, \~ 15 ml of autologous blood was injected at the extrapleural space through the coaxial needle. Then the central stylet was reinserted and the coaxial needle was advanced into the lung parenchyma with a single puncture. The needle was stopped inside the proximal part of the target and the center needle was removed. A 20-G/16 cm fully-automated biopsy needle was introduced through the 19-G/13.8 cm coaxial needle and specimens were identically obtained. After specimens were collected, the biopsy needle was removed, and immediately the remaining autologous blood (\~5 ml) was slowly injected through the coaxial needle as it was withdrawn through the parenchyma thus sealing the needle tract.

If the patient was assigned to IABPI-alone, after collecting the biopsy specimens, immediately the autologous blood (\~5 ml) was slowly injected through the coaxial needle as it was withdrawn through the parenchyma thus sealing the needle tract.
