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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Experimental: GORE Excluder
GORE Excluder Iliac Branch Endoprosthesis arm with 'ILIAC ENDOPROSTHESIS GORE EXCLUDER'
Device: ILIAC ENDOPROSTHESIS GORE EXCLUDER
Set up of GORE ® Excluder Iliac Branch Endoprosthesis in endovascular barring of complex aneurysms without distal neck. In the immediate post-operating follow-up visit and at the 3 months visit and the 12 months visit after surgery, an ultra-sound scan, a tomodensitometric exam and a walking test on a treadmill with oximetric gluteal region exploration will systematically be performed.

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
Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion (binary criterion)
Time Frame: At the immediate post-operating follow-up visit

Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion. It is a binary criterion (permeable or not) This criterion will be evaluated by a doppler ultrasound. These exams will be performed by a unique vascular physician, who will measure the hemodynamic criterions and the associated gluteal region oximetry.

Endoprosthesis will be considered to be permeable if the patient is asymptomatic (absence of gluteal claudication), if Doppler ultrasound and angio-scan confirm the permeability of the endoprosthesis.
At the immediate post-operating follow-up visit
Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion (binary criterion)
Time Frame: at 3 months after surgery

Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion. It is a binary criterion (permeable or not) This criterion will be evaluated by a doppler ultrasound. These exams will be performed by a unique vascular physician, who will measure the hemodynamic criterions and the associated gluteal region oximetry.

Endoprosthesis will be considered to be permeable if the patient is asymptomatic (absence of gluteal claudication), if Doppler ultrasound and angio-scan confirm the permeability of the endoprosthesis.
at 3 months after surgery
Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion (binary criterion)
Time Frame: at 12 months after surgery

Primary permeability maintenance of the iliac branch endoprosthesis, following its insertion. It is a binary criterion (permeable or not) This criterion will be evaluated by a doppler ultrasound. These exams will be performed by a unique vascular physician, who will measure the hemodynamic criterions and the associated gluteal region oximetry.

Endoprosthesis will be considered to be permeable if the patient is asymptomatic (absence of gluteal claudication), if Doppler ultrasound and angio-scan confirm the permeability of the endoprosthesis.

Primary permeability will be considered non-maintained at 1 year if a stenosis >70% or a thrombosis of the hypogastric branch is observed by ultra-sound scan at a follow-up visit during the first year after surgery or at a ultra-sound scan exam motivated by pelvic ischemia clinical signs
at 12 months after surgery

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
Morbidity
Time Frame: peri-operative, at short term (3 months), mean-term (12 months)

Evaluation of the morbidity:

  • Minor events (no revision surgery needed):

    • General: pulmonary, cardiologic, renal
    • Local: hematoma, false aneurysm, Impaired wound healing

  • Major events (revision surgery needed):

    • Endoleak
    • Thrombosis
    • Rupture
peri-operative, at short term (3 months), mean-term (12 months)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
