Outcomes for One-stage and Two-stage Brachial Basilic Arteriovenous Fistulas

September 9, 2025 updated by: Tze-Woei Tan

Understanding the Patient-Centered Outcomes for One-stage and Two-stage Brachial Basilic Upper Extremity Arteriovenous Fistulas: A Pilot Trial

An arteriovenous (AV) fistula is essential for patients with kidney failure on dialysis. There is no clear data on the best method to create a new brachial basilic AV fistula (BBAVF), so the choice between a single procedure and two separate procedures is left to the surgeon. Both approaches are standard care. This study aims to compare patient-centered outcomes and quality of life by randomly assigning patients needing a BBAVF to either a one-stage or two-stage procedure.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of the pilot trial is to compare the outcomes of patients with end stage kidney failure (ESKD) who are candidates for a new brachial basilic arteriovenous fistula (BBAVF). Patients will be randomized to either one-stage or two-stage BBAVF procedure, both standard of care for creating BBAVF. The main outcome will be primary clinical functional patency, defined as successful use of BBAVF over a continuous 4-week period without any need for additional procedure on the BBAVF. The secondary outcomes are fistula-related complications, duration of central venous catheter (CVC) for those on dialysis, and quality of life (QoL) measures. The study hypothesizes that the primary patency will be superior following the two-stage BBAVF procedure compare to one-stage procedure. However, CVC-related complications are expected to be higher following the two-stage procedure compared to the one-stage procedure. Patient will be followed for a minimum duration of 12-months per subject.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: One stage approach
To create a brachial-basilic arteriovenous fistula (BBAVF) using a one-stage approach. The arteriovenous anastomosis is performed and the basilic vein is transposed during the same procedure.
Procedure: One stage approach
Upper extremity brachial basilic arteriovenous fistula will be created either using one stage or two stage approach.
Other Names:
  • Two stage approach
Active Comparator: Two Stage approach
To create a BBAVF using a two-stage approach, the arteriovenous anastomosis is performed during the first procedure. The superficialization or transposition of the fistula is then performed 6 to 8 weeks later, after the fistula has matured.
Procedure: One stage approach
Upper extremity brachial basilic arteriovenous fistula will be created either using one stage or two stage approach.
Other Names:
  • Two stage approach

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Had Successful Use of Arteriovenous Fistula for Dialysis
Time Frame: 6 months
Functional clinical patency means the number of participants who were able to use their brachial basilic arteriovenous fistula (BBAVF) successfully for dialysis within 6 months of surgical creation. It refers to using two dialysis needles in at least 75% of dialysis sessions over four weeks without need for additional procedure or surgery, as determined by their providers.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Had Catheter Related Complications
Time Frame: 6 months

Number of participants with dialysis catheter related complications, including infection, procedure to exchange catheter due to malfunction.

Number of Participants Who Had > 3 Months of Catheter Dependency After Arteriovenous Creation
Time Frame: 6 months
Number of participants who had > 3 months of catheter dependency after arteriovenous fistula creation

Patient-Reported Outcomes Measurement Information System Scores Over 6 Months
Time Frame: 6-month
Average quality of life scores assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) for physical function, fatigue, sleep disturbance, and ability to participate in social roles and activities. Data are presented as T-score, which are standardized scores with a mean of 50 and a standard deviation for the reference population (typically the US general population). A T-score of 50 represents the population average. A higher T-score indicates more of the concept being measured and lower T-score indicate less.
