Brief Summary:
This is a biomedical, single-center, and prospective study of a consecutive patients cohort in acute ischemic stroke with carotid plaque.

Condition or disease Intervention/treatment Phase
Cerebral Infarction Other: Contrast injection Sonovue® Not Applicable

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).

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. Contrast enhancement of carotid plaque prevalence in ultrasound doppler [ Time Frame: Day 1 ]

Secondary Outcome Measures :
  1. Patient's demographics data [ Time Frame: Day 1 ]
  2. Patient's sonographic and MRI characteristics. [ Time Frame: Day1 ]
    confirmation of the recent character of stroke on the DWI, search for stroke sequelae and white matter disease on the FLAIR, search of the thrombus on the T2*, search occluded artery on the 3DTOF

  3. describe the aspect of the carotid plaque on CT angiography. [ Time Frame: between 1 to 5 days ]
    NASCET stenosis and the aspect (smooth, irregular, ulcerated)

  4. Persistence , decrease or loss of contrast enhancement in ultrasound doppler. [ Time Frame: Month 6 ]
  5. Cerebral infarction recurrence [ Time Frame: Month 6 ]
