Trial summary

Patients with end-stage renal disease require permanent vascular access to enable safe and effective hemodialysis. An arteriovenous fistula (AVF), where a vein is mobilized and connected to an artery in the arm, is considered the gold standard and first choice for vascular access. Read more about this study

About this study

Official title: The Effectiveness of FRAME FR for ArterioVenous Fistula Repair in High-Flow Reduction, A Prospective, Monocenter Controlled Trial

Patients with end-stage renal disease require permanent vascular access to enable safe and effective hemodialysis. An arteriovenous fistula (AVF), where a vein is mobilized and connected to an artery in the arm, is considered the gold standard and first choice for vascular access. After fistula creation, the vein is subjected to high pressure and flow, and undergoes remodeling. This includes the possibility of significant dilatation and intimal hyperplasia. Normal AVF flow required for effective dialysis is around 0.6 liters/min or 0.4-0.8 liters/min. However, in at least 20% of patients, excessive remodeling and dilatation of the fistula result in a high flow AVF with >2 liters/min.

High flow fistulas significantly increase the risk for the development of high output cardiac failure, skin breakdown, bleeding, hand ischemia, and other systemic complications. In cases of high flow AVF, venous reconstruction procedures, banding and/or plication, are often required to limit venous diameter and flow. The longevity of this procedure is limited as the reconstructed segment remodels and re-dilates due to ongoing arterial pressure. Banding and plication are both procedures that are designed to increase resistance to flow. Banding is performed by wrapping a segment of polytetrafluoroethylene (PTFE) around the outflow tract of the fistula, or by placing a suture around the fistula near the arterial anastomotic area to create a narrowing. Fistula plication involves narrowing of a short segment of the proximal venous outflow tract, usually accomplished by suturing or stapling the fistula for 2-6 cm. One of the notable systemic effects of a hemodialysis AVF is an acute decrease in systemic vascular resistance with a simultaneous increase in venous return to the heart, and thus an increase of the cardiac output. Cardiac failure occurs more frequently in patients with an access flow QA>2 l/min and CPR≥20%. Another adverse systemic effect of AV fistulas is pulmonary hypertension. The increased flow volume to the heart from an AV fistula yields an increase in pulmonary pressures. This can limit pulmonary vasodilation and result in pulmonary hypertension.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FRAME FR IFUDevice

    The surgeon will use the medical device FRAME to perform the plication procedure. The device will be selected and implanted according to the product IFU.

Study groups in NCT04795401
Study groupRoleWhat they receive
FRAME GroupExperimentalPatients will be enrolled during their hospitalization/consultation in vascular surgery department. After asking questions, his given free, informed and written consent will be collected, and recorded in his medical file by the investigator. During this hospitalization, the pre-procedure forming part of the usual care is carried out. The specific acts of research are: Cardiac echocardiography and Quality of life survey SF-36 The plication procedure will be performed according to the FRAME FR. All pre-, peri-, and post- operative routine patient management will be carried out as usual. Follow up visits will be held at 6, 12 months post procedure. All follow up visits will include the assessments as usual. The specific acts of research are as follows: Cardiac echocardiography at 12 months and quality of life survey SF-36.
Receives: Device: FRAME FR IFU
Control GroupNo interventionControl group corresponds to the historical patients over a period of time sufficient to have at least 20 patients according to inclusion criteria. The information form will be sent to each patient eligible for the study by post. Without any feedback from him within 30 days, it is considered that the patient does not object to the use of its data. As part of this research, no additional examination will be performed. The data used correspond to the data collected in the usual care of patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fistula flow Evaluation M6

    The primary outcome of the research is to evaluate the fistula flow by Doppler Us and the fistula primary patency rate over time.

    Measured: Month 6

  2. Fistula flow Evaluation M12

    The primary outcome of the research is to evaluate the fistula flow by Doppler Us and the fistula primary patency rate over time

    Measured: Month12

Secondary outcomes (6)
  1. Occurence of safety events

    This outcome corresponds to the number of safety events such as death, infection, ongoing steal, recurrent aneurysm, new cephalic arch stenosis, fistula thrombosis.

    Measured: at 6 and 12 months

  2. Evaluation of the functional fistula patency

    This ouctome corresponds to functional fistula patency.

    Measured: at 6 and 12 months

  3. Cardiac parameters

    CPR = QA/CO ratio

    Measured: at 12 months

  4. Secondary patency

    This outcome corresponds to the evaluation of thrombosis and AVF discontinuation at 6 and 12 months.

    Measured: at 6 and 12 months

  5. Patient's Quality of Life SF-36

    The SF-36 questionnaire consists of 36 items, which are used to calculate eight subscales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH). The first four scores can be summed to create the physical composite score (PCS), while the last four can be summed to create the mental composite score (MCS). Scores for the SF-36 scales range between 0 and 100, with higher scores indicating a better HRQOL.

    Measured: at 6 and 12 months

  6. Reintervention

    This outcome is to evaluate the number of patients who had a surgical or endovascular reintervention at 6 and 12 months.

    Measured: at 6 and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing FRAME FR IFU in people with Arteriovenous Fistula, run by Fondation Hôpital Saint-Joseph at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?
