CT-guided percutaneous biopsies of mediastinal and paramediastinal masses in the lateral decubitus position

Percutaneous parasternal puncture is a common procedure that allows sampling of mediastinal lesions. The trans-pulmonary route is sometimes mandatory in the dorsal position and is associated with complications such as pneumothorax. Our study explored the efficacy of the lateral decubitus position in avoiding the trans-pulmonary route. Sixteen patients were included between 2005 and 2019. In three patients, the procedure was intended to place fiducial markers. No pneumothorax or hematoma occurred. Access to the lesion was not possible in 1 patient. A histological diagnosis was made for all patients undergoing sampling. This technique seems to be safe and efficient.
