Third Ventricle Echographic Study for Neuro-intensive Care Unit Patients

Transcranial Doppler ultrasonography is usually used in the evaluation and management of patients with brain injury. This noninvasive method measures local blood flow velocity and direction in the proximal portions of large intracranial arteries. The operator requires a short training and experience to perform. The third ventricle diameter measurement by transcranial duplex flow sonography was performed in healthy volunteers . This studies show similar results in those obtained with the MRI or Computer Tomography (CT). Currently the third ventricle diameter measurements by transcranial Doppler ultrasonography was not validated for neuro-intensive care unit patients. The investigators propose to used recent ultrasound system to validate the third ventricle diameter measurements in comparison with the standard method (CT).

Treatment and study plan

Transcranial Doppler ultrasonography measurements

Device

Third ventricle diameter measurements with standard method (CT) and Transcranial Doppler ultrasonography

Primary outcomes

Third ventricle diameter (average +/- standard deviation)

Time frame: Through study completion (30 months)

Spearman's test measuring the correlation coefficient between the third ventricle diameter measured by the expert using the ultrasonography and the third ventricle diameter measured by CT scan.

Secondary outcomes

Residents' learning curve

Time frame: 24 months

The learning curve will be determined by the change in the third ventricle diameter's difference obtained by the expert and the resident, divided by the diameter obtained by the expert reported on the Y-axis and the number of measures done by the resident reported on the X-axis. Number of measures to be done will be determined when the curve reached the zero.
