This is a biomedical, single-center, and prospective study of a consecutive patients cohort in acute ischemic stroke with carotid plaque.
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).
- Contrast injection Sonovue® Other
Intervention Desc: In addition to standardized assessment routine care, a contrast injection will be performed during the neck vessels doppler ultrasound. ARM 1: Kind: Experimental Label: Acute ischemic carotid stroke Description: 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.
