摘　　要：目的分析急性脑梗死患者MRI高信号血管征(HVS)与颈内动脉狭窄程度的相关性。方法选择我院2015年11月至2017年10月收治的急性脑梗死患者277例,所有患者均进行头颈联合CTA检查,根据检查结果将患者分为颈内动脉狭窄组和颈内动脉无狭窄组,两组患者均行头颅MRI检查,比较两组HVS阳性率。将颈内动脉狭窄组狭窄程度分为不同等级,采用Spearman相关分析HVS阳性率和HVS等级与颈内动脉狭窄程度的相关性。结果颈内动脉狭窄组(n=103)HVS阳性率为52.43%,颈内动脉无狭窄组(n=174)HVS阳性率为20.11%,两组HVS阳性率比较差异有统计学意义(χ2=30.978,P<0.05);HVS阳性率与颈内动脉狭窄程度呈正相关(r=0.826,P<0.05);HVSII级率与颈内动脉狭窄程度呈正相关(r=0.793,P<0.05)。结论急性脑梗死患者MRIHVS阳性率和HVS II级率与颈内动脉狭窄程度呈正相关,HVS可有效评估颈内动脉狭窄程度。Objective To analyze the correlation between MRI high-signal vascular signs(HVS)and degree of internal carotid artery stenosis in patients with acute cerebral infarction(ACI).Methods A total of 277 cases of ACI patients admitted to our hospital from November 2015 to October 2017 were selected and were examined by CTA of intracranial and cervical arteries.According to the results of examination,the patients were divided into the internal carotid artery stenosis group and the non internal carotid artery stenosis group,and they were given cranial MRI examination,and the positive rate of HVS was compared between the two groups.The stenosis degree of the internal carotid artery stenosis group was divided into different grades.The correlation between HVS positive rate,HVS grade and degree of internal carotid artery stenosis was analyzed by Spearman correlation analysis.Results The positive rate of HVS was 52.43%in the internal carotid artery stenosis group(n=103)and 20.11%in the non internal carotid artery stenosis group(n=174),and the positive rate of HVS in the two groups was significantly different(χ^2=30.978,P<0.05).The HVS positive rate was positively correlated with the degree of internal carotid artery stenosis(r=0.826,P<0.05).The HVS II rate was positively correlated with the degree of internal carotid artery stenosis(r=0.793,P<0.05).Conclusion The MRI HVS positive rate and HVS II rate in ACI patients are positively correlated with the degree of internal carotid artery stenosis,and HVS can evaluate the degree of internal carotid artery stenosis effectively.
