摘　　要：目的探讨临床诊断老年下肢动脉硬化闭塞症采用下肢动脉CT血管造影(CT angiography,CTA)联合血管三维重建的应用价值。方法选择2022年1—12月沭阳县中医院门诊及住院接诊的50例疑似下肢动脉硬化闭塞症老年患者作为研究对象,均接受下肢动脉CTA联合血管三维重建检查,以数字减影血管造影诊断结果为金标准,统计下肢动脉CTA及血管三维重建分别诊断轻、中、重度及闭塞情况的符合率。计算下肢动脉CTA、血管三维重建及二者联合诊断老年下肢动脉硬化闭塞症的灵敏度、特异度与准确率。结果通过计算结果显示,下肢动脉CTA联合血管三维重建技术诊断灵敏度为98.00%,明显高于单一下肢动脉CTA诊断的92.00%及血管三维重建诊断的90.00%,差异有统计学意义(χ^(2)=5.571,P=0.031)。同时50例观察组下肢动脉硬化闭塞症老年患者经数字减影血管造影技术诊断,其中轻度狭窄患者15例,中度狭窄患者18例,重度狭窄患者11例,完全闭塞患者6例。经计算,下肢动脉CTA诊断总符合率为92.00%,三维重建技术诊断总符合率为90.00%,而二者联合诊断总符合率为98.00%。结论临床诊断老年下肢动脉硬化闭塞症可通过下肢动脉CTA联合血管三维重建技术,具有较高的诊断符合率。Objective To investigate the clinical value of lower extremity artery CT angiography(CTA)combined with three-dimensional vascular reconstruction in the diagnosis of elderly lower extremity arteriosclerosis obliterans.Methods A total of 50 elderly patients with suspected lower extremity arteriosclerosis obliterans who were admitted to the outpatient and inpatient departments of Shuyang County Hospital of Traditional Chinese Medicine from January to December 2022 were selected as the research objects.All patients underwent lower extremity arterial CTA combined with vascular three-dimensional reconstruction.The diagnostic results of digital subtraction angiography were used as the gold standard,and the coincidence rates of lower extremity arterial CTA and vascular three-dimensional reconstruction in the diagnosis of mild,moderate,severe and occlusion were statistically analyzed.The sensitivity,specificity and accuracy of lower extremity arterial CTA,vascular three-dimensional reconstruction and their combination in the diagnosis of lower extremity arteriosclerosis obliterans in the elderly were calculated.Results According to the calculation results,the diagnostic sensitivity of lower extremity arterial CTA combined with vascular three-dimensional reconstruction technology was 98.00%,which was significantly higher than 92.00%of single lower extremity arterial CTA diagnosis and 90.00%of vascular three-dimensional reconstruction diagnosis,and the difference was statistically significant(χ^(2)=5.571,P=0.031).At the same time,50 elderly patients with lower extremity arteriosclerosis obliterans in the observation group were diagnosed by digital subtraction angiography,including 15 patients with mild stenosis,18 patients with moderate stenosis,11 patients with severe stenosis,and 6 patients with complete occlusion.After calculation,the total coincidence rate of lower extremity artery CTA diagnosis was 92.00%,the total coincidence rate of three-dimensional reconstruction technique diagnosis was 90.00%,and the total coinci
