摘要
目的:探讨64排螺旋CT血管造影在诊断锁骨下动脉盗血综合征中的应用价值。方法:选择临床诊断锁骨下动脉盗血综合征12例患者先行64排螺旋CT检查,然后通过工作站进行后处理,包括曲面重组、最大密度投影及容积再现等,判断锁骨下动脉或无名动脉在椎动脉起始部闭塞或狭窄程度、长度及斑块性质;并与彩色超声多普勒及数字减影血管造影检查结果对照。结果:本组12例病例均行64排螺旋CT血管成像,全部行数字减影血管造影检查,6例行彩色多普勒超声检查。根据多层螺旋CT血管造影显示的狭窄部位、长度、程度,做出锁骨下动脉盗血综合征的诊断敏感性100%,特异性100%,与数字减影血管造影结果一致。结论:64排螺旋CT血管成像是评价无名动脉和锁骨下动脉狭窄或闭塞的有效方法,尤其对判断斑块性质有重要帮助,有助于锁骨下动脉盗血综合征诊断。
Purpose： To study the value of 64 - slice spiral CT angiography in diagnosis of subclavian steal syndrome. Methods： The group of twelve subclavian steal syndrome patients underwent 64 - slice spiral CT angiography. Maximun intensity projection , curved plane and volume rendering were reconstructed for subclavian and innominate artery by CTA. Results： In this group, 12 patients were underwent 64 - slice spiral CT angiog- raphy, and all cases underwent digital subtraction angiography. 6 cases underwent color Doppler ultrasonography . The results were consistent with the results of digital subtraction angiography, and the sensitivity of the diagnosis of the syndrome was 100% , Specificity of 100%. Conclusion：64 -slice spiral CTA is an effective method for the assessment of subclavian steal syndrome, especially for judges plaque.
