Abstract:
Patients with central venous occlusion who are ''tunneled catheter dependent'' are a challenge for hemodialysis access. A relatively new option for them is the hemodialysis reliable outflow (HeRO) device that can be totally implanted subcutaneously. However, patients still require a tunneled hemodialysis catheter that is used until the HeRO device is mature, 4 to 6 weeks later. Here, we describe a conversion of an existing tunneled hemodialysis catheter into a HeRO device, which was combined with a ''self-sealing'' Flixene graft. This allowed almost immediate use of the HeRO device without the need for placement of a catheter.
