Continuous Suturing Versus Interrupted Clips for Brachiocephalic AV Fistula Creation

Not Applicable
Withdrawn
Conditions
Arteriovenous Fistula
Interventions
Device: AV Fistula creation with sutures
Device: AV Fistula creation with clips
Registration Number
NCT03024372
Lead Sponsor
University of South Florida
Brief Summary

The purpose of this study is to investigate a promising strategy to improve maturation and patency rates following creation of AV fistulas and assess whether an anastomosis performed with Anastoclips (interrupted, nonpenetrating) would produce better maturation and/or patency than one performed with conventional suturing techniques.

Detailed Description

This will be a single blind (patient and dialysis center), prospective, randomized trial conducted at a single center. The study intervention will be randomization between conventional sutured anastomosis (Control group) and use of Anastoclips (Treatment group), which provide an interrupted closure without intimal penetration.

Recruitment & Eligibility

WITHDRAWN

All
Target Recruitment
Not specified
Inclusion Criteria
  • Requiring brachiocephalic fistula judged to be best option for access after vein mapping (Surgeons will be required to do 10 cases using Anastoclips prior to enrolling)
  • Able to provide informed consent in English or Spanish
  • Age 18 years or greater
  • With estimated life expectancy of 2 years or more
  • Able to comply with study procedures including all scheduled follow-up visits
Exclusion Criteria
  • Unable to provide informed consent in English or Spanish

  • Age < 18 years

  • With pacemaker, IACD, or other permanent obstructive device on that side (a temporary tunneled dialysis catheter is not an exclusion)

  • Unable (or in surgeon's judgment a poor risk) to comply with study procedures and follow-up visits

  • With estimated life expectancy of less than 2 years

  • Females must be either:

    • Of non-childbearing potential, which is defined as post-menopausal (at least 12 months without menses prior to Treatment Day) or documented surgically sterile or post hysterectomy (at least 1 month prior to Treatment Day)
    • Or, of childbearing potential, in which case must have a negative urine pregnancy test at Treatment Day
