目的 探讨颅内病变性质对X－刀治疗后并发脑水肿的影响。 方法 分析185例病人248个不同性质的病灶在X－刀治疗后并发脑水肿的情况。 结果 X－刀治疗后并发脑水肿的发生率为：脑动静脉畸形（AVM）73．33％，脑胶质瘤54．68％，脑膜瘤30％，脑转移瘤2．85％，垂体瘤、听神经瘤、颅咽管瘤未发生。 结论 颅内病变X－刀治疗后并发脑水肿与病变性质明显有关，AVM发生率较高，胶质瘤及脑膜瘤次之，脑转移瘤极底。
Objective To investigate the effect of intracranial lesions on brain edema after X-knife treatment. Methods Two hundred and eighty-eight patients with 248 lesions of different etiology and brain edema after X-knife treatment were analyzed. Results The incidence of cerebral edema after X-knife treatment was 73.33% of AVM, 54.68% of gliomas, 30% of meningiomas, 2.85% of brain metastases, Acoustic neuroma, craniopharyngioma did not occur. Conclusion Intracranial lesions after X-knife treatment complicated by cerebral edema and the nature of the disease was significantly related to the higher incidence of AVM, followed by glioma and meningioma, brain metastases at the very bottom.
