摘　　要：目的 分析头颈部CTA诊断脑血管性病变的临床应用价值。方法 选择我院在2013年9月~2014年12月收治的131例作为研究对象,患者入院后均行头颈部CTA检查及超声检查。结果 本组病例CTA发现45例脑动脉瘤,21例血管畸形。本组74例血管狭窄,轻度狭窄27例,中度狭窄21例,重度狭窄18例,闭塞8例,同时明确斑块性质,软斑块21例,钙化斑块22例,混合型斑块31例。头颈部CTA诊断脑动脉瘤、脑部血管畸形的符合率明显高于超声诊断,两种检查方法的诊断符合率存在显著性差异（P〈0.05）。结论 头颈部CTA在诊断脑部血管性病变方面具有安全快捷、准确及无创性的特点,可推广使用。Objective To analyze the clinical application value of the cranio-cervical CTA in the diagnosis of cerehrovascular diseases. Methods 131 patients who were admitted to our hospital from September 2013 to December 2014 were selected as the research objects and all patients were received cranio-cervical CTA examination and ultrasonograpby. Results 45 patients were found with cerebral aneurysm and 21 patients were found with vascular malformation. 74 patients were found with vascular stenosis and the number of these 74 patients with light, moderate and severe vascular stenosis and vascular occlusion was 27, 21, 18, 8 respectively. Plaque features were clear at the same time. The number of patients with soft plaque, calcified plaque and mixed plaque was 21, 22, 31 respectively. The coincidence rate of Cranio-cervical CTA in the diagnosis of cerebral aneurysm and cerebra] vascular malformation was significantly higher than that of uhrasonography. The coincidence rates of the two examination methods had significantly differences （P〈0.05）. Conclusion The cranio-cervical CTA in the diagnosis of cerebrovascular diseases is safe, rapid, accurate and non-invasive which is worth of promotion and application.
