摘　　要：目的探讨64排128层螺旋CT血管造影(CTA)联合彩色多普勒超声诊断糖尿病下肢血管病变的应用价值。方法回顾性分析2014年2月-2016年9月我院收治的糖尿病下肢血管病变患者128例,患者均进行64排128层螺旋CT、彩色多普勒超声及X线数字减影血管造影(DSA)检查,将DSA作为诊断标准,分析64排128层螺旋CT联合彩色多普勒超声诊断糖尿病下肢血管病变的诊断准确性。结果 CTA联合彩色多普勒超声检查正常23例,48例斑块,42例狭窄,15例闭塞;DAS检查正常23例,斑块43例,45例狭窄,闭塞17例;CTA联合彩色多普勒超声检查下肢血管病变阳性率与DSA相比,差异无统计学意义(P>0.05)。结论 CTA可清楚显示血管走向、内径等情况,彩色多普勒超声可监测血流情况,两者联合使用能在很大程度上提高诊断准确性,为临床提供可靠诊断依据。Objective To explore application value of 64-slice 128-strayum spiral CT angiography（CTA） in combination with color Doppler ultrasonography in the diagnosis of diabetic lower extremity vascular lesions.Methods One hundred and twenty eight patients with diabetic lower extremity vascular lesions admitted by the Hospital from February 2014 to April 2015 were retrospectively analyzed,64 patients were subject to 64-slice 128-strayum spiral CT and color Doppler ultrasonography and X-ray digital subtraction angiography（DSA） examination,DSA was treated as diagnostic criteria,and the diagnostic accuracy of 64-slice 128-strayum spiral CT in combination with color Doppler ultrasonography in diagnosis of diabetic lower extremity vascular lesions were analyzed.Results CTA in combination with color Doppler ultrasonography determined 23 normal subjects,48 patients with plaque,42 patients with stenosis and and 15 patients with.DAS examination determined 23 normal subjects,43 patients with plaque,45 patients with stenosis,and 17 patients with occlusion.The difference between the therapy of CTA in combination with color Doppler ultrasonography on lower extremity vascular lesions and DSA was no statistically significant（P0.05）.Conclusion CTA can clearly show the orientation and inner diameter of the blood vessel,and color Doppler ultrasonography can monitor conditions of blood flow,and their combination can improve the diagnostic accuracy to large extent,providing reliable basis for clinical diagnosis.
