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

Background 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. Methods Our study explored the efficacy of the lateral de...

Description
Summary:Background 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. Methods 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. Results 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. Key Points • Parasternal access to mediastinal and paramediastinal lesions whenever a trans-pulmonary crossing is mandatory in the dorsal position is safe, simple, and efficient in the lateral decubitus position .
