Radiation angiopathy is a well-known complication accompanying irradiation. But the majority of effected vessels are small vessels. Cases of intracranial major arteries being effected are not so numerous. We report the case of a 47-year-old female patient. The removal of pituitary adenoma was carried out on her in 1982. After that, 4500rad irradiation was performed. It was about six years after irradiation that the first angiography was made. Right MCA occlusion, multiple stenosis of both ACAs and Moya-Moya like vessels were discovered. On admission light paresis on her left lower extremity was recognized and hyperlipidemia was noted. It was interesting that the multiple stenosis was found in an area outside the irradiation field. MCA-STA anastomosis was performed and the prognosis was good. The authors described this case and reviewed the pertinent literature.
放射性血管病是放疗常见的并发症。但多数受累血管为小血管。颅内主要动脉受累的病例并不多见。我们报告一例47岁女性患者。1982年为其切除垂体腺瘤，术后进行了4500拉德的放疗。放疗后约六年进行了首次血管造影，发现右侧大脑中动脉闭塞，双侧大脑前动脉多处狭窄以及烟雾病样血管。入院时发现患者左下肢轻度瘫痪并伴有高脂血症。有趣的是，多处狭窄出现在放疗野之外的区域。进行了大脑中动脉-颞浅动脉吻合术，预后良好。作者描述了该病例并回顾了相关文献。
