Objective To observe the application value of DSA combined with US in the assessment of the association between atherosclerotic plaques and cerebral infarction. Methods Selected 100 cases patients of atherosclerotic cerebral infarction in our hospital from January to December 2014 as the observation group,and 100 healthy volunteers were selected as the control group. Two groups of patients tested with DSA and US detection,and the detection results were compared and analyzed.Results The bifurcation of the common carotid artery was the main parts of the carotid atherosclerotic plaque,US detected in 26 cases(26%),digital subtraction angiography(DSA)were detected in 36 cases(36%),agreement rate was 72.22%. Carotid artery moderate stenosis of the coincidence rate was 75%,the carotid artery severe stenosis of anastomosis rate was 88.88%. Joint inspection coincidence rate were higher than that in other parts. The occurrence of vertebral basilar artery atherosclerotic plaque was the initial segment of vertebral artery, bilateral vertebral artery and basilar artery,and US can be used in the detection of vertebral basilar artery atherosclerotic plaque.Conclusion DSA combined with US detection can accurately reflect the location and extent of carotid atherosclerotic plaque,and can be used to prevent cerebral infarction.%目的 观察DSA联合US在动脉粥样斑块与脑梗死关联性评估中的应用价值.方法 以我院2014年1~12月100例动脉粥样硬化性脑梗死患者作为观察组,同时选取100例未发生脑梗死的患者作为对照组,分别对两组患者行US与DSA检测,并对检测结果进行对比分析.结果 颈总动脉分叉处是颈动脉粥样硬化斑块发生的最主要部位,US检出26例(26.00%),DSA检出36例(36.00%),吻合率为72.22%;颈动脉中度狭窄的吻合率为75.00%,颈动脉重度狭窄的吻合率为88.88%;联合检查吻合率均高于其他部位.椎基底动脉粥样硬化斑块的发生部位由多至少分别为椎动脉起始段、双侧椎动脉以及基底动脉,US对椎基底动脉粥样硬化斑块的检出率较低,只适用于闭塞的椎动脉的判定.结论 DSA联合US检测可以准确地反映颈动脉粥样硬化斑块位置与狭窄程度,用于预防脑梗死.
