目的 探讨脑动静脉畸形 (AVM)X刀治疗的方法、疗效及术后CT、MRI随访的影像学改变。方法 利用MEVATRONMD 744 5医用直线加速器配合CREATXST -SYS治疗系统 (X刀 )治疗脑AVM 6例 ,并进行 2 4个月临床随访与 4次以上CT、MRI扫描观察。结果 6例症状消失或明显好转 ,CT、MRI片示AVM闭塞、缩小 ,有效率达 10 0 %。AVM开始闭塞与缩小时间最早为治疗后 6个月。结论 X刀治疗是脑AVM首选治疗手段 ,主要靶点是供血动脉 ,治疗后 6个月进行第 1次增强CT或MRI扫描观察。
Objective To investigate the treatment of cerebral arteriovenous malformation (AVM) X knife and its therapeutic effect and the imaging changes after CT and MRI follow-up. Methods Six cases of brain AVM were treated with MEVATRONMD 744 5 medical linear accelerator combined with CREATXST - SYS treatment system (X knife), followed by 24 months clinical follow - up and 4 or more CT and MRI scans. Results 6 cases disappeared or significantly improved symptoms, CT, MRI showed AVM occlusion, reduced, the effective rate of 100%. AVM began to occlude and reduce the earliest time after 6 months of treatment. Conclusion X knife treatment is the first choice of treatment of brain AVM. The main target is the feeding artery. The first CT or MRI scan is performed 6 months after the treatment.
