Incidence, Characteristics and Evolution of Cerebral Vasospasm With Clinical Impact in Moderate to Severe Traumatic Brain Injury Complicated by Subarachnoid Hemorrhage at Martinique University Hospital

"Neurological monitoring by daily TCD will be carried out.~* If monitoring finds, between 3rd and 12th day of treatment, a neurological deterioration or an uncontrolled increase in intracranial pressure, a new cerebral CT scan will be performed, as recommended in such a case.~* As part of this research, a specific interventional act will be implemented: additional brain perfusion scan sequence which would allow the radiological diagnosis of CV.~* Interventions related to improving cerebral perfusion and reducing intracranial pressure recommended in head trauma patients will be implemented without modification of management linked to protocol.~The additional perfusion sequences will be analyzed independently and blindly by 2 experienced interventional neuroradiologists (double reading blinded to the patient's characteristics)."
