105例脑AVM患者行伽玛刀治疗,术后随访12~44月。按Spetzler-Martin法分类,术后41月病巢闭塞率为Ⅱ度875%,Ⅲ度681%,Ⅳ度706%,Ⅴ度30%,Ⅵ度667%。病灶周围水肿62例(占590%),48例在6~18月出现。脑水肿持续6~38月(平均147月)。5例脑出血(2例为再出血),1例灶区形成囊肿。无放射性坏死或死亡病例。病巢完全闭塞后6~28月未见复通。探讨并发症的发生机制、相关因素及预防措施。应重视并发症,强调随访的重要性
105 cases of brain AVM patients underwent gamma knife treatment, followed up for 12 to 44 months. According to the Spetzler-Martin method, the rate of occlusion of the nest at 41 months after operation was 87.5%, 68%, 73.6%, 30%, 66.7%, respectively. Edema around the lesion in 62 cases (59 0%), 48 cases occurred in 6 to 18 months. Brain edema lasts 6 to 38 months (mean, 14 July). 5 cases of cerebral hemorrhage (2 cases of rebleeding), 1 case of cyst formation area. No cases of radioactive necrosis or death. Nest completely blocked 6 to 28 months after no pass. To explore the mechanism of complications, related factors and preventive measures. Should pay attention to complications, emphasizing the importance of follow-up
