Clinical Trial: Continuous Suturing Versus Interrupted Clips for Brachiocephalic AV Fistula Creation
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional
Official Title: A Prospective Randomized Single Blinded Study of Continuous Suturing Versus Interrupted Clips for Brachiocephalic AV Fistula Creation
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 Summary: 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.

Current Primary Outcome: Time to loss of primary patency [ Time Frame: one year post surgery ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Time to loss of secondary patency [ Time Frame: one year post surgery ]
- Time to loss of assisted primary patency [ Time Frame: one year post surgery ]
- Rate of functional maturation [ Time Frame: one year post surgery ]in patients on dialysis
- Time to functional maturation [ Time Frame: one year post surgery ]in patients on dialysis
- Rate of assumed maturation [ Time Frame: one year post surgery ]in patients not on dialysis
- Time to assumed maturation [ Time Frame: one year post surgery ]in patients not on dialysis
- Rate of complications [ Time Frame: 30 days post surgery ]thrombosis/thrombectomy, stenosis, skin erosion, limb swelling, steal syndrome, bleeding and hematoma formation at surgical site, surgical-site-related infection, access-related infection, rupture, revision
- Rate of intervention [ Time Frame: five years post surgery ]to maintain patency
- Operative cost [ Time Frame: duration of surgery ]
- Overall cost [ Time Frame: time of surgery to time of hospital discharge (can range from 1 day to 1 week or more) ]Overall cost of surgery itself defined as from surgery to point of hospital discharge, anticipated to be in days
- Time to loss of primary patency [ Time Frame: 5 years post surgery ]
- Time to loss of assisted primary patency [ Time Frame: 5 years post surgery ]
- Time to loss of secondary patency [ Time Frame: 5 years post surgery ]
Original Secondary Outcome: Same as current
