Internal jugular vein catheterization and catheter insertion slipped into the cervical spinal canal: a special case report.

This paper reports a case of accidental entry of an internal jugular vein catheter into the cervical spinal canal. A male patient in his fifties sustained injuries in a road traffic accident. During the placement of a catheter into the right internal jugular vein, the catheter inadvertently entered the cervical spinal canal, though no damage was caused to the spinal cord or nerves. A second successful puncture and catheter placement was performed under ultrasound guidance, and the patient eventually made a full recovery and was discharged. This case is extremely rare and of particular clinical significance, highlighting the importance of monitoring during the insertion and removal of catheters for internal jugular vein puncture.
