早期CT环池形态变化与急性颅脑损伤病人预后关系的研究

Clinical study of the correlation of status of the basal cisterns on CT scanning and the prognosis in acute brain injury patients

目的前瞻性研究急性颅脑损伤患者早期CT扫描征象的环池形态和中脑变形程度与病人预后的关系,以指导临床的治疗。方法对132例病人早期CT扫描,在中脑水平准确测量环池宽度,分6个组记录数据。同时观测中脑有无变形及测量其前后径与横径之比。治疗后按GOS标准,随访3个月,评定疗效。结果通过比较,环池宽度>1mm者有较佳的预后;中脑无变形及前后径与横径之比为0.9∶1.1者的预后较佳。结论研究得出,环池形态、中脑受压变形能作为急性颅脑损伤患者预后判断的指标,并为临床医师治疗方案提供重要依据。

Objective To prospectively study the correlations of status of the basal cisterns, the degree of midbrain deformation on CT scanning and the prognosis of patients for directing treatment. Methods The width of the basal cisterns, the ratio of occipitofrontal diameter and transverse diameter of the midbrain were measured and the observation of midbrain deformation on early CT scanning in 132 patients with acute brain injury were made, and the outcome were assessed after 3 months. Results The width of the basal cisterns was above lmm and the ratio of occipitofrontal diameter and transverse diameter of the midbrain was 0.9 - 1.1 that had good outcome. Conclusion The data shows that the status of the basal cisterns and the degree of midbrain deformation maybe useful for neurosurgeons to predict the prognosis and treatment of the patients.
