摘　　要：目的探讨颈动脉粥样硬化斑块近心端角度与新生血管评分的相关性,及二者对预测脑梗死再发的临床价值。方法选取行颈动脉斑块超声检查患者88例。根据CT或MRI结果分为非脑梗死组(45例)和脑梗死组(43例),进行常规超声检查后均行超声造影检查,常规超声测量斑块长度、厚度及近心端角度,超声造影模式显示斑块近心端新生血管评分情况,并进行比较分析。结果脑梗死组斑块厚度、近心端角度及新生血管评分大于非脑梗死组(P<0.05),而斑块长度无统计学意义;脑梗死组斑块近心端新生血管评分2或3分者比例高于非脑梗死组(79.1%vs.24.4%,P<0.01)。所有患者斑块近心端角度与新生血管评分呈正相关(r_(s)=0.374,P<0.01);新生血管评分预测脑梗死的受试者工作特征(ROC)曲线下面积与近心端角度比较差异无统计学意义(P>0.05),且获得近心端角度最佳临界值为18.8°,预测脑梗死再发的敏感度和特异度分别为93.0%和62.2%。脑梗死组患者1年再发梗死7例(16.3%),再发梗死患者的颈动脉斑块近心端新生血管评分均较高,角度均大于18.8°。结论颈动脉斑块近心端角度与新生血管评分有较强相关性,对脑梗死的再发有积极预警作用,可为临床提供可靠的辅助诊断依据。Objective To explore the correlation between the proximal angle of carotid atherosclerotic plaques and neovascularization scores,and their clinical application value in predicting recurrent cerebral infarction.Methods A total of 88 patients who underwent carotid plaque ultrasound examination in our hospital were selected.According to CT/MRI results,patients were divided into the non-cerebral infarction group(45 cases)and the cerebral infarction group(43 cases).Conventional ultrasound examination was performed followed by contrast-enhanced ultrasound.Plaque length,thickness and proximal angle were measured,and the neovascularization score of the proximal end was evaluated using contrast-enhanced ultrasound,and the results were compared and analyzed.Results In the cerebral infarction group,plaque thickness,proximal angle,and neovascularization score were significantly higher than those in the non-cerebral infarction group(P<0.05),while there was no significant difference in plaque length.The proportion of plaques with a proximal neovascularization score of 2 or 3 was higher in the cerebral infarction group than those of the non-cerebral infarction group(79.1%vs.24.4%,P<0.01).A positive correlation was found between the proximal angle and neovascularization score in all patients(r_(s)=0.374,P<0.01).There was no significant difference between the area under the ROC curve for neovascularization score in predicting recurrent cerebral infarction and the proximal angle(P>0.05).The optimal cutoff value of the proximal angle was 18.8,and the sensitivity and the specificity for predicting recurrent cerebral infarction were 93.0%and 62.2%.In the cerebral infarction group,seven patients(16.3%)had recurrent infarction within one year,and these patients had higher proximal neovascularization scores,with angles greater than 18.8°.Conclusion There is a strong correlation between proximal angle of carotid plaques and neovascularization score,which has a positive predictive role in the recurrence of cerebral infarction,providing a
