Summary

Dialysis vascular accesses called arteriovenous fistulas ( AVF) are essential to ensure extra-renal purification by hemodialysis for patients with chronic end-stage renal disease. Complications of dialysis AVF cause significant morbidity and hospitalization. Dialysis AVF angioplasties are frequently used to treat stenosis, the 1st complication concerning them and which announces the complete thrombosis which may be the definitive loss of the AVF. Historically performed under X-ray, the progression in the quality of ultrasound scanners allows today to perform this procedure under echo-Doppler guidance and thus to avoid both radiation and the injection of iodinated contrast products and their complications. It is thus possible to preserve residual renal function, a situation with a better prognosis, or to help the maturation of the AVF without precipitating the patient towards dialysis. The procedure can then be less costly, requiring a much lighter infrastructure.

The complication rates of ultrasound angioplasty remain poorly known because only a few series have been published. In addition, the evolution of the echo-Doppler parameters of the AVF is unknown during angioplasty and it is difficult to know which are the most reliable to distinguish during the procedure a "good angioplasty gesture" from an incomplete angioplasty to be continued. The proposed study would provide initial insight into the question posed.
