摘要
目的分析下肢动脉CT血管造影(computed tomography angiography,CTA)诊断糖尿病下肢动脉血管病变(lower extremity arterial disease,LEAD)的价值。方法选取2022年11月—2024年5月邹城市人民医院收治的102例疑似LEAD患者,均接受CTA、彩色多普勒超声检查,于检查7 d后行血管数字减影(digital subtrac⁃tion angiography,DSA)检查,以DSA为金标准,分析CTA、彩色多普勒超声的诊断效果。结果102例LEAD患者中,DSA共检出97例阳性,占比95.10%;彩色多普勒超声共检查85例阳性,占比83.33%;CTA共检查出93例阳性,占比91.18%。彩色多普勒超声灵敏度为85.57%(83/97)、阴性预测值为17.65%(3/17),低于CTA的94.85%(92/97)、44.44%(4/9),差异均有统计学意义(χ^(2)=4.726,4.500;P均<0.05)。结论CTA可有效诊断LEAD,具有良好的诊断效能。
Objective To analyze the value of CT angiography(CTA)in the diagnosis of diabetic lower extremity arte⁃rial disease(LEAD).Methods A total of 102 patients with suspected LEAD admitted to Zoucheng People's Hospital from November 2022 to May 2024 were selected.All patients underwent CTA and color Doppler ultrasound.Digital subtraction angiography(DSA)was performed 7 days after examination.DSA was used as the gold standard to analyze the diagnostic effect of CTA and color Doppler ultrasound.Results Among 102 LEAD patients,97 cases were positive for DSA,accounting for 95.10%.A total of 85 cases were positive by color Doppler ultrasound,accounting for 83.33%.A total of 93 CTA cases were positive,accounting for 91.18%.The sensitivity and negative predictive value of color Doppler ultrasound were 85.57%(83/97)and 17.65%(3/17),which were lower than the sensitivity of CTA 94.85%(92/97)and negative predictive value 44.44%(4/9),and the differences were statistically significant(χ^(2)=4.726,4.500;all P<0.05).Conclusion CTA can effectively diagnose LEAD and has good diagnostic efficacy.
