Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

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.

Detailed Description

From January 2006 to December 2010, the covered (experimental group) or bare stent (control group) was used in 131 and 127 patients, respectively. The recurrence rates of gastrointestinal bleeding and refractory hydrothorax/ascites, the cumulative restenosis rates in 1, 2, 3, 4, and 5-years, the incidence rate of hepatic encephalopathy, the rate of secondary interventional therapy, the 1, 2, 3, 4 and 5-year survival rates were compared between the experimental group and the control group.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders 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.
Experimental: covered stent

Procedure/Surgery: Jugular vein puncture and catheterization. Device: RUPS-100 (COOK Company) sheath, 8 mm balloon, Pigtail catheter, 8 mm covered stents (Bard, Fluency).

Drug (including placebo): No Biological/Vaccine: No Radiation: No Behavioral (e.g., Psychotherapy, Lifestyle Counseling): No Genetic (including gene transfer, stem cell and recombinant DNA): No Dietary Supplement (e.g., vitamins, minerals): No.
Device: covered stent
A broad range of implant diameters and lengths for the treatment of in-stent restenotic peripheral and central lesions* in patients with AV grafts and AV fistulae Small incremental stent graft lengths to help maintain venous real estate and cannulation area Minimal shortening and radiopaque markers aid in excellent placement accuracy
Other: bare stent

Surgery: Jugular vein puncture and catheterization. Device: RUPS-100 (COOK Company) sheath, 8 mm balloon, Pigtail catheter, 8 mm bare stents (EV3, protégé; Cordis, Smart).

Drug (including placebo): No Biological/Vaccine: No Radiation: No Behavioral (e.g., Psychotherapy, Lifestyle Counseling): No Genetic (including gene transfer, stem cell and recombinant DNA): No Dietary Supplement (e.g., vitamins, minerals): No.
Device: bare stent

A one piece laser cut, self-expanding nitinol stent combining a micromesh design with a multi segmental construction.

The 36 strut, 6 bridge construction of the Stent provides an unmatched balance of radial force, scaffolding, and longitudinal stability.

The design offers crush recoverable flexibility in the most challenging vasculature, with optimal wall apposition, conformability and minimal foreshortening.

It offers a broad portfolio of sizes for the treatment of routine and challenging Iliofemoral lesions.

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
restenosis/occlusion rate
Time Frame: up to 5 years
The cumulative restenosis rate in 1, 2, 3, 4, or 5-year
up to 5 years

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
