Clinical application of radiofrequency ablation-assisted coaxial trocar biopsies for pulmonary nodules at a high risk of bleeding.

Context: The purpose of this study was to assess computed tomography (CT)-guided puncture biopsy of pulmonary nodules at a high risk of bleeding. First, a coaxial trocar technique was used to radiofrequency ablate small blood vessels in the puncture area, followed by a biopsy of the pulmonary nodule.

Aim: This study aimed to evaluate the effectiveness and safety of this procedure.
