To assess the role of cerebrospinal fluid diversion in posterior fossa tumor surgery.
Descriptive study.
This study was conducted at the Department of Neurosurgery, Pakistan Institute of Medical Sciences (PIMS), Islamabad from February 2000 to July 2002 over a period of two and-a-half years.
Clinical, radiological and operative records of the patients who were operated for posterior fossa tumors were studied. Absolute and relative frequencies of the patients who were managed with external ventricular drainage (EVD) or ventriculoperitoneal shunt (VPS) were determined. Mean age and male to female ratio were also noted.
There were 48 patients who were operated for posterior fossa tumors. Mean age was 23 years. Male to female ratio was 1.2:1. VPS was done in 14 patients (29%) pre-operatively, in one patient (2%) per-operatively and in 2 patients (4%) postoperatively. EVD was done in 33 patients out of whom 2 patients were shunted post-operatively. Sixty-five percent of the patients remained shunt-free.
Although management of hydrocephalus secondary to posterior fossa tumors is controversial, majority of the patients need temporary cerebrospinal fluid diversion
评估脑脊液引流在颅后窝肿瘤手术中的作用。
描述性研究。
本研究于2000年2月至2002年7月在伊斯兰堡巴基斯坦医学科学研究所（PIMS）神经外科进行，为期两年半。
对接受颅后窝肿瘤手术患者的临床、影像学及手术记录进行研究。确定接受脑室外引流（EVD）或脑室腹腔分流术（VPS）治疗患者的绝对和相对频率。同时记录患者的平均年龄及男女比例。
48例患者接受了颅后窝肿瘤手术。平均年龄23岁。男女比例为1.2:1。14例患者（29%）术前进行了VPS，1例患者（2%）术中进行了VPS，2例患者（4%）术后进行了VPS。33例患者进行了EVD，其中2例患者术后进行了分流。65%的患者无需分流。
尽管颅后窝肿瘤继发脑积水的治疗存在争议，但大多数患者需要临时脑脊液引流
