Contrast Enhanced Ultrasound of Carotid Plaque in Acute Ischemic Stroke (CUSCAS)

March 14, 2018 updated by: Dr Jean-Michel BAUD, Versailles Hospital
This is a biomedical, single-center, and prospective study of a consecutive patients cohort in acute ischemic stroke with carotid plaque.

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

The main objective of this study is to evaluate the prevalence of the contrast taking carotid plaques in these acute ischemic strokes.

The secondary objectives are:

  • to determine the clinical, sonographic, CT scanner and MRI characteristics of patients in constituted acute cerebral ischemia with carotid atherosclerotic plaque taking contrast to the doppler ultrasound.
  • to explore of the plaque contrast enhancement at 6 months (new injection).

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.

Enrollment (Actual)

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • All patients aged at least 18 years hospitalized with ischemic stroke signs in the carotid territory, objectified on brain MRI with positive DWI.
  • Carotid plaque > 2.5 mm thickness in the ipsilateral carotid territory to the AIC, low echogenicity (Type 1, 2, 3, and 4a of the classification Geroulakos) measured by the assessment "GSM" (median gray level).
  • Free and informed consent patient or his representative for contrast injection microbubble.
  • Affiliated to health insurance.

Exclusion Criteria:

  • Severe cerebral infarction with NIHSS> 25
  • No-indications to the contrast medium injection
  • Recent myocardial infarction, unstable angina.
  • Heart failure stage III / IV New York Heart Association.
  • Cardiac shunt left-right, respiratory distress.
  • Allergy to albumin or contrast agents.
  • Carotid plaques and hyperechoic calcified (however these plaques will be counted to determine their prevalence in acute AIC).
  • Carotid dissection

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: Acute ischemic carotid stroke

Patients hospitalized in the neurovascular intensive care unit for an acute ischemic stroke with a carotid plaque responding to inclusion criteria.

These patients receive a contrast injection Sonovue® will be performed during the neck vessels doppler ultrasound.
Other: Contrast injection Sonovue®
In addition to standardized assessment routine care, a contrast injection will be performed during the neck vessels doppler ultrasound.

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
Time Frame
Contrast enhancement of carotid plaque prevalence in ultrasound doppler
Time Frame: Day 1
Day 1

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
Patient's demographics data
Time Frame: Day 1
Day 1
Patient's sonographic and MRI characteristics.
Time Frame: Day1

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.
