颈部血管彩超、CTA联合评估颈内动脉狭窄与前循环急性脑梗死

Evaluation of Carotid Duplex Ultrasound and CTA in Internal Carotid Artery Stricture and Anterior Circulation Acute Cerebral Infarction

目的探讨彩超(DUS)、CT血管造影(CTA)在颈内动脉狭窄所致前循环急性脑梗死中的应用价值。方法回顾性分析2016年7月—2017年3月该院收治的资料完整的150例疑诊颈内动脉狭窄的临床资料,其中100例经MRI及临床证实的前循环急性脑梗死病例为实验组,另以50例无前循环急性脑梗死患者为对照组。所有患者均行颈部血管彩超检查,并在3 d内行CTA检查,观察两组颈内动脉粥样斑块所致狭窄情况。结果实验组颈内动脉粥样斑块发生率为79%(DUS)及77%(CTA),对照组为10%(DUS)及10%(CTA),两组差异有统计学意义(P<0.05);DUS与CTA在发现颈内动脉斑块所致血管狭窄方面具有较好的,差异无统计学意义(P>0.05),但DUS显示血管中重度狭窄程度结果略高于CTA评估结果。结论颈动脉狭窄与前循环急性脑梗死的发病存在关联性,DUS可作为颈部动脉狭窄的筛选手段,与颈动脉CTA检查手段相结合,可较好评价颈内动脉狭窄情况。

Objective To discuss the value of carotid duplex ultrasound and CTA in internal carotid artery stricture and anterior circulation acute cerebral infarction. Methods The clinical data of 150 cases suspected with internal carotid artery stricture admitted and treated in our hospital from July 2016 to March 2017 were reviewed and 100 cases of patients with anterior circulation acute cerebral infarction were selected as the experimental group and 50 cases without the anterior circulation acute cerebral infarction were selected as the control group, and all patients underwent the carotid duplex ultrasound examination, and CTA examination in 3 d, and the nternal carotid artery stricture of the two groups was observed.Results The differences in the incidence rates of internal carotid artery atherosclerosis patches tested by the DUS and CTA between the experimental group and the control group were statistically significant,（79%, 77% vs 10%, 10%）, and the differences were statistically significant（P〈0.05）, and the DUS and CTA showed that there was a good correlation（P〉0.05）,but the evaluation effect of DUS was better than that of CTA in internal carotid artery stricture. Conclusion The internal carotid artery stricture and anterior circulation acute cerebral infarction have a certain correlation, and the DUS can be used as the screening means of internal carotid artery stricture.
