下肢动脉狭窄闭塞性疾病影像学诊断对比研究

目的：探讨64层螺旋 CT 血管造影与彩色多普勒超声用于下肢动脉狭窄或闭塞性疾病诊断的临床价值。方法回顾性分析2012年5月—2015年6月张家口市第一医院就诊的疑似下肢动脉狭窄或闭塞性疾病患者130例，对所有患者64层螺旋 CT 血管造影及彩色多普勒超声诊断进行分析总结，观察两种诊断方法的灵敏度、特异度和准确度。结果64层螺旋 CT 血管造影诊断的灵敏度和准确度明显高于彩色多普勒超声，差异有统计学意义（P ﹤0.05）。结论64层螺旋 CT 血管造影可用于诊断下肢动脉狭窄或闭塞性疾病。

A Comparative Study on Imaging Examination in Diagnosis of Stenosis or Occlusive Diseases in Lower Extremity Arteries

Objective To investigate clinical value of 64 layer spiral CT angiography and color Doppler ultra-sound in diagnosis of stenosis or occlusive diseases in lower extremity arteries. Methods Clinical data of 130 patients suspected as having stenosis or occlusive diseases in lower extremity arteries during May 2012 and June 2015 was respec-tively analyzed. Examination results of 64 layer spiral CT angiography and color Doppler ultrasound of all patients were al-so retrospectively analyzed. The sensitivity,specificity and accuracy of two methods were observed. Results Values of sensitivity and diagnostic accuracy of 64 layer spiral CT angiography were significantly higher than those of color Doppler ultrasound,and the difference was statistically significant(P ﹤ 0. 05). Conclusion The 64 layer spiral CT angiography can be used in diagnosis of stenosis or occlusive diseases in lower extremity arteries.
