摘要
目的分析多层螺旋CT血管成像对2型糖尿病足下肢动脉病变的诊断效果。方法选取该院2017年1—6月收治的31例2型糖尿病足下肢动脉病变患者,均行双下肢多层螺旋CT血管成像,在MSCTA检查后12 h内行DSA检查,扫描从肾动脉水平位的主动脉到足底,获取相关数据。所有检查数据均选择该院放射科两位医师对数据、狭窄程度(分三级)、吻合度进行评价与综合评估。结果采用MSCTA诊断的31例患者图像质量较佳,采集的图像清晰、分辨率高,且各分支血管狭窄、闭塞经造影创建后较清楚,检出狭窄动脉血管节段411个,经DSA检查共检出399个,两种诊断方法对比差异无统计学意义(P>0.05)。经MSCTA诊断准确度、特异度、敏感度、阳性预测值和阴性预测值均较高。结论 MSCTA诊断结果清晰与DSA具有相当效用,也可以作为临床诊断糖尿病ASO的评价手段,可在临床广推应用。
Objective To analyze the diagnostic effect of multi-slice spiral CT angiography on lower extremity arterial disease in type 2 diabetic foot. Methods 31 patients with type 2 diabetic foot lower extremity arterial disease in our hospital from Jancuary to June 2017 were treated with multi-slice spiral CT angiography of the lower limbs, 12 h examination after MSCTA examination, DSA scan from the renal artery level to the foot of the aorta, to obtain the relevant data. All the examination data were selected from two radiologists in our hospital. The data, the degree of stenosis（three grades） and the degree of anastomosis were evaluated and evaluated. Results the MSCTA diagnosis of 31 cases of patients with better image quality, the image is clear, high resolution, and each branch vascular stenosis and occlusion by angiography after the creation of the clear detection of stenosis arteries segment 411, examined by DSA were detected in 399, compared the difference between the two diagnostic methods of no significance（P0.05）. The diagnostic accuracy, specificity, sensitivity, positive predictive value and negative predictive value of MSCTA were higher. Conclusion the diagnostic results of MSCTA are clear and have considerable effect on DSA, and can also be used as an evaluation tool for clinical diagnosis of diabetes ASO, and can be widely applied in clinical.
