title: Endovascular stent-graft treatment for graft-vein anastomotic stenosis in haemodialysis patients with arteriovenous grafts.
abstract: BACKGROUND
  In this study, we investigated the patency of endovascular stent grafts in haemodialysis patients with arteriovenous grafts, the modes of patency loss, and the risk factors for re-intervention.
  
  
  METHODS
  Haemodialysis patients with graft-vein anastomotic stenosis of their arteriovenous grafts who were treated with endovascular stent-grafts between 2008 and 2013 were entered into this retrospective study. Primary and secondary patency, modes of patency loss, and risk factors for intervention were recorded.
  
  
  RESULTS
  Cumulative circuit primary patency rates decreased from 40.0% at 6 months to 7.3% at 24 months. Cumulative target lesion primary patency rates decreased from 72.1% at 6 months to 22.0% at 24 months. Cumulative secondary patency rates decreased from 81.3% at 12 months to 31.6% at 36 months. Patients with a history of cerebrovascular accident had a significantly higher risk of secondary patency loss, and graft puncture site stenosis jeopardised the results of stent-graft treatment.
  
  
  CONCLUSIONS
  Our data can help to improve outcomes in haemodialysis patients treated with stent-grafts for venous anastomosis of an arteriovenous graft.
