Abstract

We describe a case of an epidural catheter entrapment without knotting, kinking, shearing or breakage confirmed by CT scan and how to manage it. A patient was admitted for tibial fracture repair under general anaesthesia with an epidural. At discharge day, multiple attempts to retrieve the catheter were made. Contrast CT scan showed the catheter anchored in the left posterior-lateral epidural space. Despite the absence of guidelines regarding epidural catheter entrapment, all the methods described in the literature were used. This is a rare complication and it may be associated with neurological and infectious complications. Radiologic imaging should be obtained to better characterise the catheters’ position and plan removal. In this case, tension in the paraspinal muscles or in the supraspinous and intraspinous ligaments could explain the entrapment. General anaesthesia with the non-depolarising muscle relaxant allowed muscles and ligaments to relax and we were able to retrieve the catheter intact.

Resumen

Describimos un caso de atrapamiento de un catéter epidural sin atar, torcer, cortar o romper, confirmado por TC, y cómo manejarlo. Un paciente fue ingresado para la reparación de una fractura de tibia bajo anestesia general y una epidural. El día del alta se hicieron múltiples intentos para retirar el catéter. La TC con contraste mostró un catéter anclado en el espacio epidural posterolateral izquierdo. A pesar de la ausencia de directrices sobre el atrapamiento del catéter epidural, se utilizaron todos los métodos descritos en la literatura. Esta es una complicación rara y puede estar asociada a complicaciones neurológicas e infecciosas. Se deben obtener imágenes radiológicas para caracterizar mejor la posición de los catéteres y planificar la retirada. En este caso, la tensión en los músculos paraespinales o en los ligamentos supraespinoso e intraespinoso podría explicar el atrapamiento. Una anestesia general con relajante muscular no despolarizante permitió que los músculos y ligamentos se relajaran y pudimos recuperar el catéter intacto.
