Ultrasound Guided Cervical Selective Nerve Root Block Versus Fluoroscopic Guided Cervical Transforaminal Epidural Block

This study retrospectively analyzed medical records and imaging records (ultrasound images, fluoroscopy-guided images) of US-CSNRB and FL-CTFEB procedures performed at the Yangsan Pusan National University Hospital Pain Clinic outpatient department from May 1, 2019, to April 30, 2024. It compared the therapeutic effects (pain reduction), procedure-related indicators (comparison of contrast agent spread), safety (incidence of complications), and changes in analgesic usage. The primary outcome of this study is the difference in pain chage (Visual Analogue Scale, VAS) between patients undergoing US-CSNRB and FL-CTFEB. The secondary outcomes are comparison of contrast agent spread and comparison of procedure-related complication rates.
