Echoes through the Waves: Ultrasound-guided Foreign Body Removal

Purpose or Learning Objective: We provide a guide on using ultrasound for the removal of foreign bodies. We discuss the visualization of foreign bodies, the necessary skills for extraction, and the pre- and postprocedural recommendations, supported by practical examples from our clinical experience.

Methods or Background: Ultrasound is a key tool for identifying and guiding the removal of foreign bodies, offering real-time imaging that provides precision and safety during the procedure. Successful extraction relies on a solid understanding of anatomy, imaging skills, and the appropriate tools. Preprocedural ultrasound helps pinpoint the foreign body's location and its relationship with surrounding structures. Postprocedural evaluation ensures complete removal and detects complications. Due to the complexity of these procedures, many physicians are hesitant to perform them, making the radiologist's expertise essential for effective and safe removal.

Results or Findings: Through clinical case examples, we demonstrate how ultrasound can be adapted to various scenarios based on the location and nature of the foreign body, whether plastic, glass, splinters, fish bones, or metal. We detail the materials and tools used for each case, offering key technical recommendations to optimize procedural success and minimize complications. The approach is customized according to the foreign body's characteristics and location, requiring adjustments in both imaging techniques and extraction methods. We also discuss techniques such as digital ischemia to reduce bleeding and nerve blocks to facilitate extraction and improve patient tolerance. By providing practical insights and case-based examples, we present a comprehensive framework for effectively integrating ultrasound into foreign body removal procedures.

Conclusion: Ultrasound-guided foreign body removal is a safe and effective method, with the radiologist's expertise essential for precise and successful outcomes.
