Inadvertent Knot Formation on a Lumbar Epidural Catheter: A Rare Complication

Year: 2025

Type: article

Abstract: The knotting of an epidural catheter is an unusual complication that can result in disfunction of the catheter, difficult removal and may require surgical management.We report a case of knot formation on a lumbar epidural catheter, introduced at the L2-L3 level, which presented difficulty during withdrawal. Lumbar CT images were taken to evaluate the knot position and discuss posible solutions. The catheter was successfully removed without breakage, showing a simple knot 7 mm from its end. No neurological complications were observed. This case report demonstrates that knot formation in a lumbar epidural catheter is possible. Anesthesiology professionals should consider this complication when experiencing resistance during catheter withdrawal or injection.
