摘　　要：目的 :探讨听神经瘤伽玛刀术后并发脑积水的相关因素。方法 :回顾性研究 5 8例行伽玛刀治疗后随访时间 12～ 2 6个月 (中位数 18个月 )的听神经瘤患者 ,多变量 L ogistic回归分析和单变量卡方检验行统计学处理。结果 :伽玛刀术后脑积水的发生率为 14.3% ,术前均无脑积水且增强均匀或基本均匀的肿瘤中 ,术后有无肿瘤内坏死的两组患者中 ,脑积水发生率经卡方检验有统计学意义 (P=0 .0 1)。结论 :听神经瘤伽玛刀术后并发脑积水与术后肿瘤内坏死相关。Objective:To evaluate the relative factor of delayed hydrocephalus after gamma knife treatment of acoustic neurinomas.Method:We reviewed 58 patients with acoustic neurinoma treated by gamma knife,follow-up ranged from 12-26 months(media,18 months).Multivariate logistic regression analysis and univariated chi-square test were used to evaluate the relative fac tor of delayed hydrocephalus.Result:The occurrence rate of delayed hydrocephalus was 14.3% .Some patients without hydrocephalus and whose tumor were homoge neous or almost homogeneous contrast enhancement were to be postoperative hydrocephalus and/or the necrosis of tumor,the hydrocephalus was significantly associated with the necrosis of tumor with chi-square test([WT9.,8.5BX]P=0 01).Conclusion:The delayed hydrocephalus is in relation to the necrosis of tumor.\;
