该文报告伽玛刀治疗３３例隐匿型脑血管畸形。幕上２６例、幕下７例，病灶体积平均８．０４ｃｍ３（０．３９～５０．４０ｃｍ３）。术后随访３～３６个月，病灶缩小２０例（６０．６１％），其中有１０例缩小６０％以上，无改变１１例（３３．３３％），增大２例（６．０６％）。病灶周围出现脑水肿９例（２７．２７％）。临床症状改善１９例，不变７例，症状加重７例。故认为，伽玛刀治疗隐匿型脑血管畸形有一定的临床价值，但还需要进一步的探索研究。
The article reports gamma knife treatment of 33 cases of occult cerebrovascular malformations. 26 cases were on the screen, 7 cases were under the screen, and the average lesion volume was 8.04cm3 (0.39 ~ 50.40cm3). The patients were followed up for 3 to 36 months. The lesions were reduced in 20 cases (60.61%). Among them, 10 cases were reduced by 60% or more, 11 cases were unchanged (33.33%) and 2 cases (6.06% . There were 9 cases of cerebral edema around the lesion (27.27%). Clinical symptoms improved in 19 cases, unchanged in 7 cases, symptoms increased in 7 cases. Therefore, gamma knife treatment of occult cerebrovascular malformations have some clinical value, but still need further exploration and research.
