Vascular Access Stenosis

Abstract There is amassed evidence regarding the use of endovascular procedures for the treatment of vascular access stenosis and thrombosis. A review was conducted based on available randomized trials, cohort studies and retrospective analyses published after 2000 on endovascular treatment of dysfunctional and thrombosed vascular access, with an aim to illustrate the available device and procedural options. The use of paclitaxel-coated balloons, cutting balloons and covered stents is described in the field of vascular access stenosis. The broad spectrum of available devices and endovascular declotting procedures ranging from thrombolysis to thrombectomy is also discussed. Overall, in this review we demonstrate the increasing role of endovascular procedures in vascular access treatment and the improved patency outcomes provided by the implementation of novel endovascular devices. Moreover, the improvement of post-intervention primary patency rates after endovascular declotting procedures and the shift to more thrombectomy-dependent procedures over time is also highlighted. In conclusion, endovascular treatment of dialysis access stenosis and thrombosis has an established role, owing to the implementation of sophisticated devices, allowing, when needed, the simultaneous treatment of thrombosis and the underlying stenosis.

Graft Implantation

Swing-segment lesions are a fairly common reason for access failure and predispose to repeated interventions. The pathophysiology, hemodynamic circumstances and the primary intervention might all play a role in early recurrence. Mainly, percutaneous transluminal angioplasty (PTA), bare metal stenting and stent graft implantation have been performed to prolong lesion patency and access circuit patency. The available data on endovascular treatment of swing-segment lesions are scarce, heterogeneous and of poor quality. Moreover, with the continuous evolution of endovascular techniques and introduction of new devices there is a risk of increasing device-specific investigations. In the meantime, PTA is easily discarded in favor of novel stents and stent grafts. However, PTA might still have an important position in the overall treatment strategy to postpone loss of the vascular access site. However, without optimal post-interventional imaging, true PTA results remain obscure and indications for additional stent (graft) implantation unclear. Currently, it seems that different devices are utilized to prolong lesion patency rather than access circuit patency. Obviously, more randomized controlled trials and well-structured multicenter registries may be capable of determining a superior treatment modality for a specific lesion. However, it might be more accurate to identify the optimal sequence of interventions by which the lifespan of the access site is maintained as long as possible.
