摘要：目的： 探讨环池变化在脑挫裂伤并发颅内血肿中的临床意义。 方法：对209例脑挫裂伤并发颅内血肿的动态环池CT扫描变化进行回顾性分析，判断环池变化与预后的关系。结果： 环池结构正常或部分变窄又恢复者预后好；环池部分变窄趋于加重后完全闭塞或完全闭塞无好转者预后差。 结论： CT环池结构变化对脑挫裂伤并发颅内血肿的治疗及预后有重要意义，可作为判断预后的一个客观指标。

    Abstract: Objective: To determine the clinical significance of ambient cisterna′s change on cerebral contusions and lacerations accompanying with intracranial hematoma. Methods: The dynamic CT changes of ambient cisterna of 209 patients with cerebral contusions and lacerations accompanying with intracranial hematoma were analyzed retrospectively, and the associations of ambient cisterna′s change and clinical prognosis were determined. Results: The clinical prognosis was fine in the patients either with normal texture of ambient cisterna or with restored ambient cisterna after partly narrowing. The clinical prognosis was bad either in the patients that partly narrowed ambient cisterna aggravated gradually and obliterated completely or in that ambient cisterna had obliterated completely and no amelioration. Conclusion: It was of important significance of the CT changes of ambient cisterna in treatment and prognosis of the patients with cerebral contusions and lacerations accompanying with intracranial hematoma. The CT changes of ambient cisterna could be used as a objective index to predict the prognosis. ......
