Percutaneous Anastomosis Creation for Hemodialysis Access

The investigators propose to adult patients needing the creation of a vascular access for hemodialysis, not eligible to the creation of a distal AVF, to create a percutaneous anastomosis between an artery and a vein (endo-AVFs). The study is a prospective single-center cohort (Nice University Hospital) with a 2-year follow-up (recruitment: 18 months, length of study per patient: 24 months, data analysis: 6 months). After the procedure, patients will receive duplex-ultrasound follow-up, according to local practice, at 6 weeks (+ surgical examination), 3, 6, 12, 18 and 24 months.
