Analysis of diagnostic value of early CT in traumatic intracranial hemorrhage
Objective To explore the diagnostic value of early CT in traumatic intracranial hemorrhage.Methods 239 patients with head trauma and coma were selected as the study subjects.The imaging[CT and/or magnetic resonance imaging(MRI)]and medical records of the patients'early CT and late diagnosis and treatment were collected to clarify whether cerebral hemorrhage,bleeding location and bleeding amount were present on the CT signs of the patients,and follow-up data were further obtained to determine the actual craniocerebral injury.The difference between patients with early CT examination and those with late definitive bleeding in the bleeding site and bleeding volume was compared.Results Among 239 patients with head trauma,188 patients(78.66%)were diagnosed with cerebral hemorrhage at a later stage by imaging and surgery,and 51 patients(21.34%)had no cerebral hemorrhage.Early CT was accurate in 167 cases(69.87%),missed in 21 cases(8.79%),and misdiagnosed in 18 cases(7.53%).The diagnostic sensitivity of early CT for traumatic cerebral hemorrhage was 88.83%,the specificity was 64.71%,and the area under the curve(AUC)was 0.768[95%confidence interval=(0.685,0.851),P<0.001].The amount of blood loss in basal ganglia[(18.32±3.85)ml]and ventricular area[(18.44±4.02)ml]assessed by early CT was significantly lower than the actual amount of blood loss[(34.23±5.94),(27.31±4.92)ml]determined at a later stage(P<0.05).Conclusion Early CT has a good value in the detection of traumatic cerebral hemorrhage,but some parts of cerebral hemorrhage still need to be further improved head MRI or surgical exploration to complete the diagnosis.
