摘要： 目的评价血管超声检查在颈部动脉病变检测中的准确性。方法对53例提示有慢性脑供血不足、短暂性脑缺血发作、脑梗死患者颈部75条动脉同时进行血管超声及数字减影血管造影(DSA)检查;以DSA为标准,用四格表法分析血管超声检查对血管狭窄程度为中度、重度及闭塞(血管管腔直径狭窄分别为50%—69%、70%—99%、梗阻)的颈部动脉病变检出的敏感性、特异性及准确性。结果血管超声检查对中度、重度血管狭窄及血管闭塞颈部动脉病变检出的敏感性、特异性及准确性各自分别为85.7%、78.9%、84.0%;90.2%、88.2%、89.3 %;93.3 %、95.0%、94.6%,两种检查的完全相符率为73.3%。结论血管超声检查技术对颈部动脉病变,特别是严重狭窄或梗阻性病变的检测中有较高的准确性,可以广泛应用于临床。

Abstract: ObjectiveTo evaluate the accuracy of the vascular ultrasound testing technique on detecting large arterial lesions in neck. MethodsVascular ultrasound testing and digital substraction angiography(DSA) were performed on 75 arteries in 53 consecutive patients with chronic cerebral ischemia, transient ischemic attack(TIA) or cerebral infarction.The sensitivity, specificity, and accuracy of vascular ultrasound testing on moderate stenosis(50%—69%), severe stenosis(70%—99%),or occlusion of arterial lesions in neck were analysed by means of cross tabulation, using DSA as the standard of reference. ResultsThe sensitivity, specificity and accuracy of vascular ultrasound testing on arterial lesions of moderate stenosis, severe stenosis and occlusion were 85.7%,78.9%,84.0%;90.2%,88.2%,89.3%;93.3%,95.0%,94.6%,respectively.The complete corresponding rate between the two type of tests was 73.3%. ConclusionThe vascular ultrasound testing technique shows high accuracy on detecting large arterial lesions, especially on severe stenosis or occlusion in neck. It can be applied extensively in prevention and treatment of cerebrovascular diseases.
