目的 探讨128层螺旋CT血管成像在颅颈血管疾病诊断中的价值。方法 回顾性分析我院近年来收治的80例头颈部血 管病变患者128层螺旋血管成像资料，并由两名放射医生分别应用Siemens公司Syngo工作站进行图像后处理，结果 一致时诊断成立。结果 56例头颈部血管疾病的患者，经128层螺旋CT血管成像，显示颅内动脉瘤5例，其中大脑前 动脉动脉瘤2例，大脑中动脉动脉瘤l例，颈内动脉颅内段动脉瘤l例，前交通动脉动脉瘤l例；136例患者血管有不 同程度的动脉狭窄，部分病人有颈部及颅内多支血管病变；颈动脉闭塞5例；动静脉畸形3例；烟雾病3例；颈内动 脉夹层动脉瘤1例；头臂干动脉瘤样扩张1例；右侧颈总动脉动脉瘤样扩张1例；大脑大静脉动脉瘤样扩张2例；锁骨 下动脉闭塞3例。结论 128层螺旋CT血管成像对颅颈血管疾病的诊断具有准确、快速的特点，值得临床推广使用。

Objective To evaluate the clinical value of 128-slice spiral CT angiography in diagnosing craniocervical vascular disease. Methods The CT images of 80 patients with documented craniocervical vascular disease were analyzed retrospectively by 2 cardiovascular radiologists. When consistency was obtained by the independent interpretations, the diagnosis of craniocervical vascular disease could be confirmed. Results Among 80 patients examined by CTA, 5 were diagnosed as cerebral aneurysms, and 56 were diagnosed as different degrees of arterial stenosis, which partly involved multivessel, 5 were diagnosed as carotid artery occlusion, 3 were diagnosed as AVM, 3 were diagnosed as moyamoya disease, 1 was diagnosed as dissecting aneurysm of internal carotid artery, 1 was diagnosed as aneurysmal expansion of brachiocephalic artery, 1 was diagnosed as aneurysmal expansion of right common carotid artery, 2 were diagnosed as aneurysmal expansion of galea vein, 3 were diagnosed as subclavical artery. Conclusion 128-slice CT angiography in the diagnosis of craniocervical vascular disease is accurate and rapid characteristics, is worthy of clinical use.
