目的:探讨伽玛刀治疗后顽固性脑水肿影响因素。方法:以年龄,病灶部位、边缘剂量、平均直径为影响因素,分组对比顽固性脑水肿发生率。结果:年龄>50岁组显著高于<50岁组;脑实质或凸面组显著高于颅底病灶;边缘剂量>16 G y组显著高于<16 G y组;直径>40 mm组显著高于<40 mm组,三组P值均<0.01。结论:顽固性脑水肿与年龄,病灶部位、直径、边缘剂量密切相关,值得重视。
Objective: To investigate the influencing factors of refractory cerebral edema after gamma knife treatment. Methods: Age, lesion location, marginal dose and mean diameter were used as the influencing factors to compare the incidence of intractable cerebral edema. Results: The age> 50 years old group was significantly higher than <50 years old group; the brain parenchyma or convex group was significantly higher than the skull base lesion; the marginal dose> 16 Gy group was significantly higher than <16 Gy group; In the <40 mm group, all three P values were <0.01. Conclusions: Intractable cerebral edema is closely related to age, lesion location, diameter and marginal dose, which deserves attention.
