Effect of Inflation on the Angiographic Result After Balloon Angioplasty in the Femoropopliteal Segment (Balloon-angio)

March 8, 2019 updated by: Cliniques universitaires Saint-Luc- Université Catholique de Louvain

Effect of Different Inflation Times on the Angiographic Result After Balloon Angioplasty in the Femoropopliteal Segment: a Prospective Randomized Clinical Trial

Percutaneous angioplasty with balloon dilation is the method of choice for the treatment of most femoropopliteal artery lesions. After balloon dilatation, arterial wall dissection with flow limiting dissection or recoil with residual stenosis often require additional procedures such as stent placement or prolonged balloon dilation. A shorter balloon inflation time of 30 sec will be accompanied by a higher number of flow limiting dissection or recoil, demanding a time consuming and expensive stent placement or balloon redilatation. The effect of different balloon inflation times has only been assessed ones in peripheral balloon angioplasty with better outcomes after prolonged balloon inflation.

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.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

45 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with symptomatic atherosclerotic stenotic lesions of the femoropopliteal artery suitable for angioplasty in the adult population

Exclusion Criteria:

  • Artery lesions shorter than 1 cm and longer than 10 cm length, total occlusions, severe calcification, previous angioplasty with current restenosis, previous stenting with current insistent restenosis and subintimal recanalization of the lesion

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 residual stenosis between both groups
Time Frame: at 3 or 5 minutes

The primary outcome of the study is to assess the difference in number of residual stenosis after balloon dilatation of the arterial lesion between both groups (3min and 5min). A residual stenosis (measured on the angiogram) responsible for an arterial stenosis of >30% will be defined as unsuccessful treatment.

The group with the lowest number of arterial restenosis >30% after dilatation has the best primary outcome.
at 3 or 5 minutes

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 redilatation or additional stenting between both groups
Time Frame: at 3 or 5 minutes
The secondary outcome of the study is to evaluate the difference in need of redilatation or provisional stenting after the first dilatation between both groups (3 vs 5min). If an arterial stenosis of >30% after dilatation is measured, a redilatation of an additional stenting will be placed. The group with the lowest number of redilatation or additional stenting after dilatation has the best secondary outcome.
at 3 or 5 minutes
