Intraluminal catheter plasty. An alternative technique to remove tethered abdominal surgical drains.

objectiveRetained surgical drains can lead to significant complications including gastrointestinal fistulae, abscess formation and intestinal obstruction. Today, there is little in the literature describing the role of Interventional Radiology (IR) in assisting the removal of surgical drains. We describe the use of the well-established intraluminal catheter plasty technique, previously used for the removal of adhered central venous catheters, in order to remove a tethered abdominal drain. METHODS AND MATERIALS: A 67-year-old female was referred to the IR department for the removal of a 24 Fr Robinson's intra-abdominal surgical drain that could not be removed by conventional methods, as there was a concern that it was kinked internally. Both fluoroscopy and cone beam CT were performed, which identified the drain to be sited within the pelvis with no kinks.A first attempt to remove the drain over a 0.035 stiff wire was unsuccessful due to resistance and patient discomfort. We suspected that this was due to adhesions surrounding the drain. Consequently, a 9 × 40 mm angioplasty balloon was used over the wire with serial dilatations along the drain to disrupt the adhesions. Several areas of waisting were identified. The drain was gently withdrawn over the wire with minimal resistance.

conclusionWe describe a safe and effective novel technique of intraluminal catheter plasty used to remove a tethered surgical drain following failed conventional methods.
