研究概览
简要总结
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.
详细描述
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.

入选标准
- •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
排除标准
- •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
