Retained epidural catheter: A rare complication. Report of two cases

Conclusion To prevent these potential complications, refrain from passing excessive catheter length and do not leave more than 5cm of catheter into the epidural space. If a catheter cannot be easily removed, try using several maneuvers and if these fail or there is any pain or paresthesia, diagnostic imaging is required to locate the catheter and request neurosurgery support.
