脑室腹腔合流术治疗特发性正常颅压脑积水

Analysis on the Diagnosis and Treatment of Idiopathic Normal Pressure Hydrocephalus

目的：探讨特发性正常颅压脑积水(INPH)的诊断和手术治疗标准。方法：应用二级预测试验,作为是否选择手术治疗的标准,采用脑室腹腔分流手术治疗INPH 25例。结果：无手术死亡病例,未出现分流管排异反应、分流管堵塞、感染等现象。随访1～4年,总体改善率达92%。结论：应用二级预测试验,作为选择手术的标准,具有良好的阳性预测率,在临床上可靠易行。根据脑脊液压力选择分流管类型也很关键。

Objective：To investigate the diagnosis and surgical （INPH）. Methods.. Utilizing the two step prognostic test as the treatment criteria of idiopathic normal pressure hydrocephalus criteria, to determine the 25 probable INPH patients be treated by cerebrospinal fluid ventriculo- peritoneal shunt. Results： There were no death because of surgery and no complications such as shunt rejection, shunt obstruction and infection of the 25 cases. All the patients were followed up 1-4 years. The general ef fective rate of surgical therapy was 92%. Conclusion：It is effective, trustworthy, and convenient to use the two step prognostic test as the criteria. It is also important to select the shunt type according to the cerebrospinal fluid pressure.
