ABSTRACT
OBJECTIVE:
This study is designed to identify the clinical characteristics and the optimal treatment modality of hydrocephalus in posterior fossa tumors.METHODS:
The authors reviewed 154 infratentorial tumor patients. Age, sex, clinical symptoms, types of treatment, and surgical results of posterior fossa tumor patients with hydrocephalus were analyzed, retros-pectively. Factors which might predict the need for external ventricular drainage(EVD) or ventriculo-peritoneal shunt were analyzed statistically.RESULTS:
Hydrocephalus was noted in 86 cases(56%), and it was associated with medulloblastoma in 16 cases(89%), hemangioblastoma in 12(63%) and brain stem glioma in three(33%). The surgical results of the posterior fossa tumors with hydrocephalus were poorer than those without hydrocephalus(p<0.05). A large tumor(p<0.05) and an incomplete removal(p<0.05) were factors predicting the need for EVD or shunt. Complications of intraoperative EVD or shunt developed in four cases. They were infection, he-morrhage at puncture site, and obstruction. Five patients in whom intraoperative EVD or shunt had not been performed developed a fatal hydrocephalic attack at immediate postoperative period, and the pos-toperative computed tomography scan revealed intraventricular hemorrhages in three cases cerebellar swellings in two cases.CONCLUSION:
Intraoperative EVD or shunt is a safe, effective treatment modality especially in large size tumor and/or incomplete tumor resection. Intraventricular hemorrhages or cerebellar swellings during immediate postoperative period might cause fatal hydrocephalic attack, therefore EVD or shunt might be recommended in selected cases.
