AbstractTo investigate the efficacy and safety of percutaneous micro-balloon compression (PBC) assisted by Dyna-CT-based image fusion technique in the treatment of trigeminal neuralgia (TN). This study is the retrospective analysis of the efficacy and safety of 18 patients with TN treated by PBC assisted with Dyna-CT-based image fusion technique from May 2020 to May 2021. The puncture route from the skin to the foramen ovale（FO）was reconstructed after Dyna-CT scanning; and the puncture direction was adjusted according to the virtual puncture route until the puncture was completed. Dyna-CT-assisted puncture was successful in all 18 patients. The puncture was accurate and effectively shortened the operation time. Importantly, pain was relieved in all patients, and no puncture-related complications occurred. Dyna-CT-based image fusion real-time-assisted PBC for the treatment of TN is safe and effective, making the operation easier and faster, greatly improving the success rate of the puncture, and reducing the risk of operation-related complications. Key Words: Dyna-CT, Percutaneous micro-balloon compression, Trigeminal neuralgia.
