摘　　要：目的探讨64层CT血管成像在诊断糖尿病下肢动脉硬化闭塞症中的影像学价值。方法选取2015年12月～2017年12月我院收治的60例下肢动脉硬化闭塞症患者作为研究对象,按照患者有无糖尿病合并症,将糖尿病患者设为观察组(n=30),将无糖尿病合并症的患者设为对照组(n=30)。所有患者均采用64层螺旋CT行下肢动脉血管成像检查,依据动脉造影12分段积分法将所有患者的下肢动脉分为12个阶段。采用最大密度投影(MIP)、曲面重建(CPR)、矢状多平面重建(CPR)以及容积再现(VR)等技术进行图像重建。分析两组的各个血管节段的管腔狭窄程度、斑块检出率以及斑块性质。结果两组患者的膝上各个分段血管管腔狭窄程度总积分比较,差异无统计学意义(P>0.05);观察组患者的膝以下各个分段血管管腔狭窄程度总积分均明显高于对照组,差异有统计学意义(P<0.05);两组患者的膝上血管区域斑块检出率及斑块性质比较,差异无统计学意义(P>0.05);观察组患者的膝以下血管区域斑块检出率明显高于对照组,且两组的斑块性质比较,差异有统计学意义(P<0.05)。结论下肢动脉硬化闭塞症在糖尿病患者中的患病率较高,且膝以下病变程度较重,64层CT血管成像在诊断糖尿病下肢动脉硬化闭塞症中有较高的斑块检出率,并且能够有效检出斑块性质,对下肢动脉硬化闭塞症的诊断有较高的临床应用价值。Objective To investigate the imaging value of 64 slice CT angiography in the diagnosis of diabetic lowerextremity arteriosclerosis obliterans. Methods A total of 60 cases of lower extremity arteriosclerosis obliterans treatedin our hospital from December 2015 to December 2017 were selected as the subjects. According to the patients＇ diabetes complication, diabetic patients were set up as the observation group （n=30）. The patients without diabetes complication were set up as the control group （n=30）. All patients were examined by 64-slice spiral CT for lower extremityarterial angiography, and the lower extremity arteries of all patients were divided into 12 stages according to the 12 segment integral method of arteriography. Maximum intensity projection （MIP）, surface reconstruction （CPR）, sagittal multiplanar reconstruction （CPR） and volume rendering （VR） were used to reconstruct the images. The stenosis degree,plaque detection rate and plaque character of each vascular segment in the two groups were analyzed. Results Therewas no statistically significant difference in the degree of stenosis between the two groups （P〉0.05）. The total integral ofthe stenosis degree of the vascular lumen below the knee in the observation group was significantly greater than that inthe control group, and the difference was statistically significant （P〈0.05）. There was no significant difference in plaque detection rate and plaque nature between the two groups （P〉0.05）. The plaque detection rate in the area below the kneewas significantly higher than that in the control group. The plaque characteristics of the two groups were compared, andthe difference was statistically significant （P〈0.05）. Conclusion Arteriosclerosis obliterans of lower limbs has high morbidity rate in diabetic patients, and the lesions below knee are more severe. 64 layers of CT angiography has a high detection rate in the diagnosis of diabetic lower extremity arteriosclerosis obliterans, and can effectively detect
