摘要
目的探讨彩色多普勒超声(color doppler ultrasound,CDUS)与CT血管造影成像(computerized tomography angiography,CTA)在评估缺血性脑血管病患者颈动脉粥样斑块性质中的应用价值。方法选取2014年6月-2017年6月就诊于我院神经内科的130例疑似缺血性脑血管病患者,均完成CDUS、CTA两种检查,比较两种检查方法在颈动脉斑块数量及易损斑块检出上的差异。结果颈总动脉(common carotid artery,CCA)260支,在钙化斑块、软斑块、混合斑块数目检出上,CDUS分别为517块、250块、322块,CTA分别为504例、244块、341块。颈内动脉(internal carotid artery,ICA)260支,在钙化斑块、软斑块、混合斑块数目检出上,CDUS分别为85块、13块、23块;CTA分别为228块、104块、85块。颈外动脉(external carotid artery,ECA)260支,在钙化斑块、软斑块、混合斑块数目检出上,CDUS数目分别为39块、10块、16块,CTA数目分别为42块、20块、23块。以两种检测方法无差异的CCA为研究对象,对比两种检查方法在易损斑块上的检出情况,结果显示,在易损斑块检出率上,超声(53.17%)明显高于CTA(22.41%)。结论 CDUS与CTA在评估缺血性脑血管病患者颈动脉粥样斑块上各有优势,两者联合使用,取长补短,有助于提高评估的准确性。
Objective To explore the value of color Doppler ultrasound(CDUS)and CT angiography(CTA)in evaluating carotid atherosclerotic plaques in patients with ischemic cerebrovascular disease.Methods 130 patients with suspected ischemic cerebrovascular disease who were treated in the department of neurology of our hospital from June 2014 to June 2017 were selected,and they were examined with CDUS and CTA.The two examination methods were compared in terms of the number of carotid plaques and detection of vulnerable plaques.Results There were a total of 260 common carotid arteries(CCA)with plaques,CDUS detected 517 calcified plaques,250 soft plaques and 322mixed plaques while the numbers of corresponding plaques detected by CTA were 504,244 and 341 respectively.There were a total of 260 internal carotid arteries(ICA)with plaques,CDUS detected 85 calcified plaques,13 soft plaques and 23 mixed plaques while the numbers of corresponding plaques detected by CTA were 228,104 and 85 respectively.There were a total of 260 external carotid arteries(ECA)with plaques,CDUS detected 39 calcified plaques,10 soft plaques and 16 mixed plaques while the numbers of corresponding plaques detected by CTA were 42,20 and 23 respectively.The detection rate of vulnerable plaques in CCA by ultrasound(53.17%)was significantly higher than that by CTA(22.41%).Conclusion CDUS and CTA have their own advantages and disadvantages in evaluating carotid atherosclerotic plaques in patients with ischemic cerebrovascular disease.The combined use of them can help to improve the accuracy of evaluation.
