    Objective: The image of the real-time ultrasound combined with pulsed Doppler system is a noninvasive and bedside method that allows the cerebral blood flow velocity and evaluation and flow resistance measurement in intracranial hypertension patients. The intracranial hypertension is an important clinical condition and represents high risk to patients with acute brain injury. In this study, we describe in an experimental model, application of cerebral duplex to evaluate changes in pre and post-intracranial hypertension.

    Critical care management of patients with traumatic brain injury (TBI) has undergone tremendous advances. Neurosurgeons, neurologists and neurointensivists, including military, have a large armamentarium of invasive monitoring modalities available to detect secondary brain injury and guide therapy. The primary goal monitoring is to prevent secondary insults to the brain, primarily cerebral ischemia due to the posttraumatic vasospasm (PTV), and intracranial hypertension (ICH). This lecture summarizes the advantages and the specific roles of transcranial Doppler (TCD) ultrasound to establish and monitor the presence of PTV and ICH.
