Abstract： 目的 探讨运用CTA诊断破裂脑动脉瘤.方法 对怀疑颅内动脉瘤破裂的40例病人施行CTA检查,采用Philips Tomoscan AVP1螺旋CT机,数据经计算机工作站处理后以最大密度投影重建(MIP)和表面遮盖法重建(SSD)法显示,由放射科医师和神经外科医师共同阅片.结果 本组40例病人共检出25例28个动脉瘤,其中前交通动脉瘤13例,颈内动脉颅内段动脉瘤3例,后交通动脉瘤2例,大脑中动脉瘤2例,眼动脉瘤1例,基底动脉梭形动脉瘤1例,左侧大脑中动脉瘤破裂合并右侧颈内动脉瘤1例,后交通动脉瘤合并同侧颈内动脉床突周围段芽孢状微小动脉瘤2例.20例脑动脉瘤做了开颅手术治疗,其中15例单纯根据CTA检查结果手术,术中证实诊断.结论 CTA具有快速、简便、安全、可靠的优点,可作为破裂脑动脉瘤和急诊手术前首选的检查.
