【摘要】：目的探讨多层螺旋CTA与超声造影在评价颈动脉斑块中的价值。资料与方法62例于我院就诊的有症状颈动脉狭窄患者分别行多层螺旋CTA及超声造影检查,分析颈动脉狭窄比率、斑块形态,超声造影评估斑块内新生血管情况,将斑块分为稳定性斑块及易损斑块。结果62例患者共计检查64条病变血管,CTA:非钙化斑块55例,钙化斑块9例(重度钙化3例);轻度狭窄19例,中度狭窄16例,重度狭窄27例,闭塞2例。超声造影:斑块内大量新生血管44例,斑块内少量新生血管20例;轻度狭窄19例,中度狭窄16例,重度狭窄27例,闭塞2例。结论超声造影与多层螺旋CTA在评估颈动脉狭窄程度方面有较好的一致性(Kappa=0.610,P0.05)。钙化斑块尤其重度钙化斑块(钙化程度45%)不一定都显示较强的稳定性,钙化斑块内也会出现大量新生血管。
[Abstract]:Objective to evaluate the value of multislice spiral CTA and contrast-enhanced ultrasonography in the evaluation of carotid plaque.Materials and methods Sixty-two patients with symptomatic carotid artery stenosis were examined by multi-slice spiral CTA and contrast-enhanced ultrasonography respectively. The carotid stenosis ratio, plaque morphology and intraplaque neovascularization were evaluated by contrast-enhanced ultrasonography.The plaques were divided into stable plaques and vulnerable plaques.Results A total of 64 lesions were examined in 62 patients: 55 cases of non-calcified plaque, 9 cases of calcified plaque (3 cases of severe calcification, 19 cases of mild stenosis, 16 cases of moderate stenosis, 27 cases of severe stenosis and 2 cases of occlusion).Contrast-enhanced ultrasonography showed that there were 44 cases of massive neovascularization in plaque, 20 cases of small amount of neovascularization in plaque, 19 cases of mild stenosis, 16 cases of moderate stenosis, 27 cases of severe stenosis and 2 cases of occlusion.Conclusion there is good consistency between contrast-enhanced ultrasonography and multislice spiral CTA in the assessment of carotid stenosis.Calcified plaques, especially severe calcified plaques (calcification degree 45) do not always show strong stability, calcified plaques will also have a large number of neovascularization.
