Suitable central venous access for hemodialysis is frequently required in patients with end-stage renal disease, whenever an arteriovenous fistula or peritoneal dialysis fails or is not a possibility. Ultimately, long-term dialysis via central access may result in dysfunctional catheter with problems such as malpositioning of catheter tip, fibrin sheath formation, thrombosis, infection, and bleeding. The role of interventional radiology is to deliver appropriate treatment to maintain patent and functional access, while minimizing the risk of venous occlusive disease. This article aims at describing different techniques and approaches for management of fibrin sheath associated with malfunctioning tunneled dialysis catheters, as well as to provide scientific evidence from the current literature.
终末期肾病患者在动静脉内瘘或腹膜透析失败或不可行时，常常需要合适的中心静脉通路用于血液透析。最终，通过中心通路进行长期透析可能会导致导管功能障碍，出现诸如导管尖端位置不当、纤维蛋白鞘形成、血栓形成、感染和出血等问题。介入放射学的作用是提供适当的治疗，以维持通路通畅和功能正常，同时将静脉闭塞性疾病的风险降至最低。本文旨在描述与隧道式透析导管功能障碍相关的纤维蛋白鞘的不同处理技术和方法，并提供当前文献中的科学证据。
