Removal of stuck tunnelled dialysis catheter
Abstract:
Tunnelled central venous dialysis catheters can usually be removed easily. However, their removal can become rarely complicated requiring more invasive techniques. We report a case in which cardiopulmonary bypass and repair of great veins was required for safe removal. A 38-year-old female with end-stage renal failure and a 3-year-old Hickman line inserted into her right internal jugular vein was referred to our cardiac surgical unit following failed attempts of line removal by local vascular surgical team using open vascular surgical techniques. As a result, an MDT decision was made that it was safer to proceed to a cardiothoracic surgical approach rather than other techniques. Investigations showed significant calcification surrounding the line which was adherent to the venous wall. Removal of the retained catheter required median sternotomy and the use of cardiopulmonary bypass as the great veins had to be opened to free the line and allow complete removal. The line was successfully removed with its encircling calcified sheath, and the veins were closed primarily without needing a patch repair. The integrity of the great veins was maintained to meet the on-going need this young patient has for central venous access. The patient made an uneventful recovery. When other measures fail, sternotomy and cardiopulmonary bypass provide a safe option for complete removal of stuck central venous catheters with low risk to the patient.
