  Purpose
The main objective of this study is to evaluate and compare the primary patency rate at 12 months in a group of hemodialysis patients operated on by cutting balloon and in a group of hemodialysis patients operated by conventional balloon.

Arteriovenous Fistula Fistula Procedure: Cutting balloon angioplasty Procedure: Angioplasty

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomized Trial Comparing a Cutting Balloon to a Non-cutting Balloon for the Treatment of Venous Stenosis in the Fistulas of Hemodialyzed Patients

Primary Outcome Measures:
  • Primary patency [ Time Frame: 12 months ]
    Primary patency following a first angioplasty of a first stenose in the affected zone.


Secondary Outcome Measures:
  • Number of early re-stenoses [ Time Frame: 3 months ]
    stenosis defined as lumen diameter < 2mm

  • Number of re-stenoses [ Time Frame: 12 months ]
    Stenosis defined as lumen diameter < 2mm

  • Total days in hospital [ Time Frame: 12 months ]
    The total number of days hospitalized for stenosis, thrombosis, or recovering vascular access. This does not include regular hemodialysis activities.

  • Number of stents used [ Time Frame: 12 months ]
    The total number of stents placed between the study angioplasty and the end-of-study visit.

  • Total number of venous thromboses [ Time Frame: 12 months ]
    Total number of venous thromboses between study angioplasty and end-of-study visit

  • Direct medical costs (€) [ Time Frame: 12 months ]
  • Indirect costs (€) [ Time Frame: 12 months ]
  • Questionnaire KDQOL [ Time Frame: 12 months ]
  • Questionnaire SF36 [ Time Frame: 12 months ]
  • Questionnaire KDQOL [ Time Frame: 3 months ]
  • Questionnaire KDQOL [ Time Frame: 6 months ]
  • Questionnaire SF36 [ Time Frame: 3 months ]
  • Questionnaire SF36 [ Time Frame: 6 months ]
  • Fistula quality (cm*ml/min) [ Time Frame: Baseline ]
    cumulative length of "usable" fistula (cm) * venous flow during the last hemodialysis (ml/min)

  • Fistula quality (cm*ml/min) [ Time Frame: 6 months ]
    cumulative length of "usable" fistula (cm) * venous flow during the last hemodialysis (ml/min)

  • Fistula quality (cm*ml/min) [ Time Frame: 12 months ]
    cumulative length of "usable" fistula (cm) * venous flow during the last hemodialysis (ml/min)

  • % Stenosis [ Time Frame: Baseline ]
    100-((the smallest diameter of the stenosis lumen (mm)/ the diameter of a proximal, normal portion of lumen (mm))*100)

  • % Stenosis [ Time Frame: 6 months ]
    100-((the smallest diameter of the stenosis lumen (mm)/ the diameter of a proximal, normal portion of lumen (mm))*100)

  • % Stenosis [ Time Frame: 12 months ]
    100-((the smallest diameter of the stenosis lumen (mm)/ the diameter of a proximal, normal portion of lumen (mm))*100)

  • Presence/absence of complications associated with the angioplasty [ Time Frame: Day of intervention ]
  • % Stenosis [ Time Frame: 3 months ]
    100-((the smallest diameter of the stenosis lumen (mm)/ the diameter of a proximal, normal portion of lumen (mm))*100)

  • Presence/absence of complications since the last visit [ Time Frame: 6 months ]
  • Presence/absence of complications since the last visit [ Time Frame: 12 months ]
