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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
This study will determine the rate of all pneumothoraces and those pneumothoraces requiring treatment following percutaneous lung biopsy in patients who have received ABPI or BioSentry at the end of the biopsy procedure. The data collected will be used to determine if there is equal effectiveness in the reduction of pneumothorax rates from both interventions.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: autologous blood patch injection (ABPI)<br> | Other: ABPI<br>* If the patient was assigned to the ABPI group, a blood patch will be administered using the clotted blood in the syringe obtained at the beginning of the procedure. The guiding needle will be retracted up to 1.5-2 cm from the pleural surface, and the blood will be injected steadily and gently as the needle is pulled back out of the pleura. Injection will stop when the operator feels the needle is in subcutaneous tissues.<br>|
| Experimental: BioSentry (formerly known as Bio-Seal) hydrogel Tract Plug<br> | Device: BioSentry (formerly known as Bio-Seal) hydrogel Tract Plug<br>* If the patient is assigned to BioSentry group, using the manufacturer's deployment device the introducer needle is positioned so that the tip is at least 1.5 cm deep to the visceral pleura. The coaxial introducer needle hub will be prehydrated with a drop of saline, the BioSentry plug housing will be mated and locked to the hub and the plug will be deployed.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the rate of pneumothorax | within 2 hours following biopsy. Pneumothorax is observed on post procedure CT scan or on follow-up chest radiographs while the patient is in the recovery room, according to standard of care. | 2 years |
