Comparison of Clinical Efficacy and Postoperative Outcomes of Ultrasound-Guided Lateral Sagittal Infraclavicular and Costoclavicular Brachial Plexus Blocks: A Retrospective Cohort Study

Background/Objectives: The costoclavicular (CCB) and lateral sagittal infraclavicular (ICB) approaches provide ultrasound-guided access to the cords of the brachial plexus. Comparative real-world evidence on imaging efficiency, block dynamics, and postoperative analgesia remains limited. We compared procedural and analgesic outcomes between these approaches.
