Effect of Autologous Blood Patch Injection Versus BioSentry Hydrogel Tract Plug in the Reduction of Pneumothorax Risk Following Lung Biopsy Procedures


The purpose of this study is to compare two methods that are currently used at the end of a CT guided lung biopsy to close the hole on the surface of the lung in order to minimize the chance of air leaking out of the hole. The two techniques consist of either injecting a very small amount of your the blood called a blood patch into the biopsy hole or injecting a gel-based FDA approved artificial plug called BioSentry that will eventually get absorbed into the body.
