摘　　要：目的探讨64排128层CT血管减影技术在头颈部血管狭窄和闭塞病变中的应用价值。方法 92例怀疑颅内外动脉狭窄或闭塞患者行64排128层CT血管减影检查,使用VR、Reformat、CPR等软件分析各血管狭窄或闭塞情况、斑块性质及狭窄与脑梗死间的关系。结果 65例患者颅内外血管均可见不同程度的狭窄或闭塞,以中、重度狭窄为主;113支血管有附壁粥样硬化斑块形成,钙化斑块、血管腔及硬化斑块CT值间差异有统计学意义(P<0.01);梗死侧颈动脉、大脑中动脉狭窄发生率与非梗死侧比较差异均有统计学意义(P均<0.05)。结论 64排CT血管减影技术能够准确地评估血管狭窄和斑块性质,为临床治疗方法的选择提供有价值的信息。Objective To explore the value of stenosis or occlusion of head and neck vessels with 64-rows 128-slice CT subtraction angiography. Methods 64-rows 128-slice CT subtraction angiography were performed in 92 patients, images were analyzed by VR, Reformat and CPR software to acquire information of stenosis or occlusion of head and neck vessels, plaque character and correlation between vessel stenosis and cerebral infarction. Results Different extent stenosis or occlusion of vessels was found in 65 among 92 suspected patients, mainly including vessel stenosis with middle and high degree; atherosclerotic plaques were observed in 113 vessels, there was significant statistical difference in calcified plaque, enhanced blood and sclerotized plaque（P〈0.01）; there was correlation between incidence of carotid artery stenosis and middle cerebral artery stenosis in infarction side and that in non-infarction side（both P〈0.05）. Conclusion 64-rows 128-slice CT subtraction angiography can accurately evaluate stenosis or occlusion of head and neck vessels and plaque character, and can provide valuable information for choice of treatment.
