目的： 探讨伽玛刀对脑深部和功能区海绵状血管瘤（ＣＡ） 的治疗效果及有关问题。方法： 采用伽玛刀对６７ 例大脑半球深部、丘脑、基底节及脑干海绵状血管瘤进行治疗。结果： 随访３ 月～８ 年 （平均２．６ 年）， 评价其治疗效果， ２ 例死于其他疾病， ６ 例行手术治疗。在ＭＲＩ检查随访５９ 例中， 病变稳定好转率达９８％ ， 并且年再出血发生率大大降低。结论： 应用伽玛刀治疗脑深部及险要部位的ＣＡ 是一种无创伤、效果比较好的方法。
Objective: To investigate the therapeutic effect of Gamma Knife on Cavernous Hemangioma (CA) in deep brain and functional areas and related problems. Methods: Gamma knife was used to treat 67 patients with deep hemispheres, thalamus, basal ganglia and cavernous hemangiomas of brain stem. Results: The follow-up ranged from 3 months to 8 years (average 2.6 years). The therapeutic effect was evaluated. Two cases died of other diseases and six cases were treated surgically. During the follow-up of MRI examination, the rate of stable improvement was 98% and the incidence of annual rebleeding was greatly reduced. Conclusion: The application of Gamma Knife in the treatment of deep brain and critical parts of the CA is a noninvasive, better effect.
