摘　　要：目的探讨超声造影与数字减影血管造影(DSA)在颈动脉狭窄诊断中的应用价值。方法选择拟诊为颈动脉狭窄并确定自愿选择DSA检查的患者,分别应用普通超声和超声造影对入组患者进行显像评估其狭窄的程度及部位,并进行相关性对比分析。结果以DSA的结果为金标准,应用普通超声和超声造影对轻、中、重度颈动脉狭窄及闭塞的诊出率分别为67.9%vs 89.3%(P<0.05),66.7%vs 91.7%(P<0.05),60.0%vs 88.0%(P<0.05),72.7%vs 90.9%(P<0.05),其中超声造影检查和DSA检查共同检查出的颈动脉血管狭窄率计算值呈明显线性正相关(r=0.988,P<0.01)。结论超声造影检查用于颈动脉狭窄的诊断优于普通超声,与DSA相关性较高,值得临床推广应用。Objective To explore the application of ultrasound contrast and DSA in patients with carotid artery stenosis. Methods Common Ultrasonic, ultrasound contrast and DSA were performed in patients suspected with carotid artery stenosis.Com-parison and correlation analysis was carried on.Results Based on the results of DSA, the consistent rates in diagnosis on mild steno-sis, moderate stenosis, severe stenosis and complete obstruction by baseline common ultrasonic and ultrasound contrast are 67.9%vs 89.3%（P〈0.05）, 66.7%vs 91.7%（P〈0.05）, 60.0%vs 88.0%（P〈0.05）, 72.7%vs 90.9%（P〈0.05）, respectively. Ultrasound contrast and DSA were correlated significantly on calculating the stenosis rate （r=0.988, P〈0.01）.Conclusion Ultra-sound contrast is superior to common ultrasonic for the diagnosis of carotid artery stenosis, correlated significantly with DSA.
