Another knotted epidural catheter.

A lumbar epidural catheter inserted in a 24-year-old woman for labour analgesia, and subsequently used for post-caesarean epidural analgesia, proved difficult to remove. After multiple attempts, the entrapped catheter was dislodged intact, revealing a knot near its distal tip. Knotting of an epidural catheter leading to entrapment is a rare complication of epidural catheterization.
