Brief Summary

Aneurysmal subarachnoid hemorrhage (SAH) is a devastating form of stroke, with three major complications : early brain injury (EBI), vasospasm and delayed cerebral ischemia (DCI). Those patients are often given care in neurocritical care. Imaging is particularly useful to diagnose these complications. Brain imaging includes CT scan, MRI and arteriography which are not easily available and need an intrahospital transportation. Furthermore, intrahospital transportation of critically ill patients is associated with significant complications Here, investigators try to show that a new non-invasive bedside device, based on 3D enhanced ultrasonography, is able to detect principal arteries of anterior circulation of the brain.

Outcome Measures

Primary Outcomes (1)

  • Presence of a time-intensity curve (TIC) of contrast agent / Quality of signal

    Mathematical models may be used to estimate blood flow parameters after the administration of microbubble contrast agents. A time-intensity curve (TIC) may be created to reflect the intravascular transit of the contrast agent. TICs reflect the average intensity in a region of interest, measured in absolute intensity units, over time in seconds. Plotting TIC in a given frame allows for quantification of various parameters, including time to peak, peak intensity, area under the curve, wash-in and wash-out time, and mean transit time. Some of these parameters, such as peak intensity and area under the curve, reflect local blood volume in the region of interest, whereas, other parameters (time to peak intensity, wash-in/wash-out time) are more reflective of blood flow.
