ENhancing Maturation of Autogenous Arteriovenous Hemodialysis Access by Aggressive surveillaNCe With Duplex and Endovascular Treatment
Not Applicable
Completed
- Conditions
- End Stage Renal Disease
- Interventions
- Procedure: Duplex ultrasonography
- Registration Number
- NCT01597115
- Lead Sponsor
- Seoul National University Hospital
- Brief Summary
The aim of this study is to evaluate whether Aggressive duplex surveillance after vascular access surgery with native vein for hemodialysis can increase the maturation rate of arteriovenous fistula. This study will be conducted as a single center, prospective, 1:1 randomized study. Enrolled patients will be randomized as a control group (Physical exam at 2 and 4 weeks after surgery) and duplex group (duplex study and physical exam at 2 and 4 weeks after surgery). Maturation of arteriovenous fistula will be evaluated at 8 weeks after surgery by duplex in all patients.
