- W2019010903 abstract "To study blood flow velocity (BFV) changes, serial transcranial Doppler ultrasound (US) examinations of basal cerebral arteries were performed in 47 patients with head injury. Computed tomographic (CT) scans obtained at admission were analyzed for the presence of intracranial hemorrhages. Glasgow Coma Scale scores were obtained at admission in 46 patients. The prevalence of posttraumatic increased BFV was 77% (n = 36). Two groups of patients were identified according to the time of onset of increased BFV. They differed with respect to duration and severity of changes, Glasgow Coma Scale score, and evidence of intracranial hemorrhagic lesions. Low Glasgow Coma Scale scores were predictive of increased BFV within 72 hours after injury (P < .001). Patients with hemorrhages were significantly more prone to experience increased BFV within 72 hours (P < .05); 34% of patients who did not have hemorrhage, however, developed increased BFV. Increased BFV after head trauma is not uniformly found and cannot be explained by one pathologic mechanism." @default.
