Case report: central venous catheter fracture due to compression between the clavicle and first rib.
A central venous catheter inserted via the subclavian route may be compressed by the clavicle and adjacent first rib. This appearance on a radiograph has been previously described as the 'pinch-off sign' and indicates the need to remove the catheter, due to a significant risk of subsequent fracture. A case and its management are presented, followed by discussion of the radiographic appearances and their cause.
