case_images: The surgeon was able to remove the entire polyurethane catheter body without difficulty, but during removal, the central stimulating wire and coil structure were noted to be fractured, with approximately 3 cm remaining above the skin level (Figure 1).
case_images: Infraclavicular neurovascular sonoanatomy with arm position adducted. The ultrasound image represents a transverse view with the top of the image displaying the ultrasound probe position. Arrows: needle shaft, A = axillary artery.

case_images: Since the arm was unable to be abducted, the infraclavicular neurovascular sonoanatomy was more challenging to interpret, as it appeared different than when the catheter was inserted (Figure 2).
case_images: Removal of the fractured peripheral nerve catheter fragment. Traction was applied to the fragment while observing real-time removal with ultrasonography. Yellow arrows: wire fragment.

case_images: The wire was successfully removed with the tip intact (Figure 4).
case_images: Follow-up ultrasound evaluation of the infraclavicular brachial plexus region with arm abducted and externally rotated. The ultrasound image represents a transverse view with the top of the image displaying the ultrasound probe position. A = axillary artery, LC = lateral cord, MC = medial cord, and PC = posterior cord.

case_images: During this follow-up visit, an ultrasound evaluation (GE Healthcare, Logiq  P6, 11L probe, Chicago, IL, USA) revealed normal infraclavicular brachial plexus anatomy when the patients arm was abducted and externally rotated (Figure 5).
