CTICasesBioSentry Hydrogel Tract Plug
Imaging findings
Serial chest CT scans in two patients post CT-guided percutaneous lung biopsy demonstrate a newly developed, thin, worm-like soft-tissue density/high-attenuation tract extending from the biopsied pulmonary nodule across the pleural space to the chest wall. This represents an in-place hydrogel plug.
Key takeaways
The BioSentry hydrogel tract plug is a medical device deployed into the needle tract immediately following percutaneous transthoracic lung biopsy. It is designed to expand upon hydration to seal the pleural puncture, thereby reducing the incidence of post-biopsy pneumothorax. On post-procedure CT, it appears as a linear, high-attenuation or soft-tissue tract and eventually dissolves over several weeks.
