摘要
目的探讨多层螺旋CT血管成像(MSCTA)在颈内动脉起始部狭窄的血管内介入治疗的应用。方法回顾性分析42例颈内动脉起始部狭窄行血管内介入诊疗的MSCTA影像资料,总结这些资料在该病治疗中的应用价值。结果MSCTA检查均能获得明确诊断。通过多平面重建测量42例84侧颈内动脉起始部的面积狭窄百分率,其中面积狭窄百分比≤50%者15支,狭窄程度在50%～70%者17支,>70%者30支,闭塞者4支,单侧正常者18例。MSCT重建技术能显示斑块及狭窄管腔内部形态。结论MSCTA可直观地显示颈内动脉起始部狭窄程度及斑块性质,在颈内动脉起始部支架内再狭窄的评价中起着重要作用。
Objective To assess the clinical value of MSCTA in the interventional treatment of the initial origin stenotic segment of internal carotid artery. Methods Forty two patients with stenosis of initial origin stenotic segment of internal carotid artery underwent interventional treatment and MSCTA were analyzed retrospectively. Results Forty two patients were diagnosed correctly through MSCTA. The percentages of stenotic area were measured from the muhiplanar reconstruction （MPR）images of MSCTA,including mild stenosis（ 〈 50%）in 15, moderate stenosis（50% ～ 70%）in 17, severe stenosis（ 〉 70%）in 30, obstruction in 4 （ 〉 100%）and normal in 18. Plaques and endoscopic views of stenosis were delineated on MSCTA and CTVE. Conclusion MSCTA is an accurate method for the assessment of the stenosis and plaques of the stenotic origin segment of internal carotid artery. MSCTA can be used as a convenient follow-up modality for instent restenosis.
