Track Sealing in CT-Guided Lung Biopsy Using Gelatin Sponge Slurry versus Saline in Reducing Postbiopsy Pneumothorax: A Prospective Randomized Study.

Purpose: To compare the effectiveness of 2 track sealing techniques following computed tomography (CT)-guided lung biopsy using either gelatin sponge slurry (GSS) or saline to reduce the rate of postbiopsy pneumothorax.

Materials And Methods: In this prospective study, a total of 266 patients (median age, 66.2 years; range, 25.

Efficacy of the tract embolization technique with gelatin sponge slurry to reduce pneumothorax and chest tube placement after percutaneous CT-guided lung biopsy.

Purpose: To assess the efficacy of the tract embolization technique using gelatin sponge slurry after CT-guided lung biopsy to reduce pneumothorax and chest tube placement rates.

Materials And Methods: We retrospectively compared 231 CT-guided lung biopsies performed with the tract embolization technique using gelatin sponge slurry (treated group) with 213 biopsies performed without embolization (control group). All procedures were performed at our institution between January 2014 and September 2018 by one of three experienced interventional radiologists using a 19-gauge coaxial needle.
