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。
Objective To observe the value of DSA combined with US in evaluating the correlation between atherosclerotic plaque and cerebral infarction. Methods One hundred patients with atherosclerotic cerebral infarction in our hospital from January to December 2014 were selected as the observation group and 100 patients without cerebral infarction were selected as the control group. The US and DSA tests were performed on the two groups The test results for comparative analysis. Results Carotid artery bifurcation was the most important site of carotid atherosclerotic plaques. US detected 26 cases (26.00%), DSA detected 36 cases (36.00%), the anastomosis rate was 72.22%. In the carotid artery The stenosis rate was 75.00%, and the anastomosis rate of severe carotid stenosis was 88.88%. The anastomosis rates of the combined tests were higher than those of other sites. Vertebrobasilar atherosclerotic plaque occurred at least from the beginning of at least the vertebral artery, bilateral vertebral artery and basilar artery, the US detection rate of vertebrobasilar atherosclerotic plaque is low, only applies to Occlusion of the vertebral artery to determine. Conclusion DSA combined with US detection can accurately reflect the location and stenosis of carotid atherosclerosis plaque for the prevention of cerebral infarction.
