NCT01643733

Brief Summary

Hypothesis: The primary objective of this study is to assess whether using a flow measurement device, in this case the Transonics flow device, as an end-point to interventional treatment of diseased dialysis fistulae can help increase immediate treatment success in terms of quality of dialysis immediately following the treatment and increasing time to reintervention.

Outcome Measures

Primary Outcomes (1)

  • Time to reintervention

    Time between intervention and the need for repeat intervention (based on standard dialysis screening systems).

    6 months

Secondary Outcomes (4)

  • Effect of treatment on rate of change in Transonics flow measurements

    Baseline, 2 weeks, one, two three and 6 months

  • Change in dialysis efficiency post treatment

    One month, 2, 3 and six months

  • Significance of stenoses as detected by Transonics, compared with angiography

    1 day, ie.will be asessed immediately following intial intervention only.

  • Nature of Procedure using Transonics versus Angiographic assessment

    Six months

Study Arms (2)

Transonics Arm

EXPERIMENTAL

Intervention will be guided by flow through the fistula as guided by Transonics flow measurements

Device: Using Flow measurements to guide fistula angioplasty (Transonics)

Control arm

NO INTERVENTION

Patient will undergo normal fistula intervention guided only by angiographic assessment

Interventions

Transonics flow measurements in the fistula would be used to guide the fistula intervention

Transonics Arm

Eligibility Criteria

Age16 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Male or non-pregnant female subjects, between the ages of 18 and 80 at the time of enrollment.
  • Subjects referred to us from the Dialysis units located in the study centres for clinically indicated fistulogram and fistula treatment.
  • Written informed consent to participate in the study.
  • Ability to comply with the requirements of the study procedures

You may not qualify if:

  • Significant coagulopathy that cannot be adequately corrected.
  • Subjects who participated in an active stage of any drug, intervention or treatment trial within 30 days of enrollment.
  • Subjects with preexisting conditions, which, in the opinion of the investigator, interfere with the conduct of the study. Patients will only be excluded on this basis following discussion with another interventional radiologist and the referring nephrologist.
  • Subjects who are uncooperative or cannot follow instructions.
  • Mental state that may preclude completion of the study procedure or ability to obtain informed consent.
  • Pregnant or nursing female subjects.
  • Patients whose fistulae have never become functional.
  • Patients with PTFE grafts/non-native fistulae
  • Patients who have had previous stenting of fistulae
