Abstract: ObjectiveTo investigate the strategy and effect of microsurgical treatment for pediatric cerebellar astrocytoma. Methods93 cases of pediatric cerebellar astrocytoma were reviewed who received microsurgical operation. ResultsTotal removal was achieved in 85 cases while subtotal in 8 cases. Pre-operatively, tumor capsule puncture was performed in 21 cases, lateral ventricle puncture and draining in 9 cases and ventricle-peritoneal shunt in 23 cases. Post-operative radiotherapy was performed in 8 cases. They were followed up for 26 months to 5 years with 8 cases lost. There was no death and recurrence. Scores of Karnofsky Performance Status (KPS) was more than 90 in all cases followed up. ConclusionPediatric cerebellar astrocytoma can be treated satisfactorily with microsurgery. By improving surgical removal rate, reasonable peri-operative treatment and early rehabilitation, children with cerebellar astrocytoma can achieve long and excellent living status.
