Outflow Stenosis

Brief summary
The purpose of this study is to demonstrate the efficacy of a PTFE covered stent-graft in the prevention of outflow re-stenosis in loop fistula in a prospective trial.
Interventions
The viabahn stent-graft is a combined ePTFE-Nitinol self-expanding stent-graft preloaded on a catheter-based delivery system. It was originally designed for improving blood flow in patients with symptomatic peripheral arterial disease in superficial femoral artery lesions with reference vessel diameters ranging from 4.8 to 7.5 mm. This device is also increasingly used for the exclusion of popliteal aneurysms. Its flexibility might make the device ideal for the treatment of recurrent outflow stenosis in AV loop-fistula.
