128层螺旋CT血管成像在颅颈血管病变诊断中的价值

The Clinical Value of 128-slice Spiral CT Angiography in the Diagnosis of Craniocervical Vascular Disease

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. Re~/~ 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.
