256层螺旋CT血管成像诊断糖尿病膝下动脉病变的临床价值

摘要

Objective To evaluate the clinical value of diabetic inferior genicular artery with 256-multi-slice CT An-giography(256-MSCTA). Methods The 256-MSCTA inspection data of diabetic foot (diabetic foot, DF) of digital subtrac-tion angiography ( DSA) diagnosis were retrospectively analyzed, and were compared with DSA examination results. Results All the patients underwent successful examinations and had satisfactroy images. A total of 1071 arterial segments were inclu-cled in the study with 965 segments evaluated by two examinations. The artery development score of 256-MSCTA was (3. 34 ± 0.21), and there was no significant difference compared to that of (3.43 ±0.37) of artery development score of DSA(P>0. 05). Conclusion 256-MSCTA in diagnosis of diabetes infrapopliteal inferior genicular artery is accurate and noninvasive, therefore it should be the first choice in replacement of DSA.%目的：评价256层螺旋CT血管成像(256-MSCTA)诊断糖尿病膝下动脉病变的临床价值。方法回顾性分析经数字减影血管造影(DSA)检查明确诊断的糖尿病足(diabetic foot, DF)147例的256-MSCTA检查资料,并与DSA检查结果进行对比分析。结果所有患者均顺利完成检查,获得满意图像,纳入研究总计1071个动脉节段,其中两种检查可评估动脉节段965个。256-MSCTA动脉显影评分(3.34±0.21)分,与DSA动脉显影评分(3.43±0.37)分比较差异无统计学意义(P>0.05)。结论256-MSCTA诊断糖尿病膝下动脉病变具有准确性高及无创等特点,可替代DSA成为该病首选检查方法。
