摘要
目的:通过研究正常压力脑积水(NPH)CT表现及脑脊液动力学在手术前后的变化以评价手术有效性。方法:所有病人均采用中压管行脑室-腹腔分流术。手术前后分别测量侧脑室额角宽度、额角间质水肿带宽度及三脑室、鞍上池大小,并观察临床症状的变化。结果:20例病人术后症状改善,CT提示脑室系统缩小,脑积水消失。结论:手术前后CT表现及脑脊液动力学的变化可以预测NPH分流手术的有效性。
Objective To predict efficacy of operation by exploring the change of CT findings and eerebrospinal fluid flow dynamics before and after shunt surgery in normal pressure hydrocephalus. Methods Twenty - eight eases with normal - pressure hydrocephalus were enrolled from April, 1997 to April ,2005. All patients had iustable gait and memory difficulty and urine irretention after craniocerebral injury and cerebral hemorrhage. Ventriculo - peritoneal shunt with medium - pressure shunts were performed in these patients. Results After follow - up from 6 months to 5 years after shunt ,20 cases among them were improved in symptoms. Hydrocephalus was disappeared in CT findings. Conclusion It is an effective method to predict the shunt efficacy by exploring the change of CT findings and cerebrospinal fluid flow dynamics before and after the operation in patients with normal pressure hydrocephalus.
