Over the last decade, it has been increasingly recognized that recirculation is present to some extent in all dual-lumen dialysis catheters. In addition, despite the recognition that dual-lumen dialysis catheters are not ideal as long-term hemodialysis access, their use for this purpose has increased secondary to both poor vascular access in an older and sicker dialysis population as well as their convenience. Although infection and thrombosis remain the most common complications of dialysis catheters, we report a case of severe access recirculation secondary to free flow between the two lumens of a tunneled, cuffed silicone dual-lumen dialysis catheter. We take this opportunity to discuss recirculation in dialysis catheters and to review potential causes of catheter breakdown.
在过去十年中，人们越来越认识到，在所有双腔透析导管中都存在一定程度的再循环。此外，尽管人们认识到双腔透析导管作为长期血液透析通路并不理想，但由于老年和病情较重的透析人群血管通路不佳以及其便利性，其用于此目的的情况有所增加。虽然感染和血栓形成仍然是透析导管最常见的并发症，但我们报告了一例因隧道式带袖套硅胶双腔透析导管两腔之间自由流动导致严重通路再循环的病例。我们借此机会讨论透析导管中的再循环，并回顾导管故障的潜在原因。
