Abstract:
Objective To evaluate the effectiveness of color doppler ultrasound(CDU)in combination of computed tomographie angiography(CTA)in diagnosis of the arteriosclerosis occlusion.Methods:43 patients with arteriosclerosis occlusion were assessed by color doppler ultrasound,CTA and digital subtraction angiography(DSA).By using DSA as the reference standard,the results were compared.Results The sensitivity.specificity,positive and negative predictive values for CDU were 82.96%,95.2%,94.92%,83.8% respectively.Those for CTA were 88.89%,96.75%,96.77%,88.81% respectively,and for the two combination,were 94.81%,99.17%,99.22%,94.44% respectively.Conclusion The color doppler ultrasound combined with CTA is an effective way in diagnosing arteriosclerosis occlusion.
