AIM
Comparison of colour coded duplex sonography (CCDS) to angiography in visualizing arteries and haemodialysis fistulas of the upper extremity.
METHOD
1145 arterial and vein segments were visualised using CCDS and angiography in 219 patients by different examiners with different degrees of experience. Sensitivity, specificity and accuracy were calculated.
RESULTS
For the arterial segments--subclavian artery up to the distal lower arm arteries--the sensitivity was 90% and the specificity 99%. The sensitivity for the detection of vascular alterations in haemodialysis fistulas was 89% and the specificity 95%.
CONCLUSION
CCDS may be able to replace diagnostic angiography of the arm except when evaluating the hand arteries and the central veins.
目的
比较彩色编码双功能超声（CCDS）与血管造影在上肢动脉及血液透析动静脉内瘘成像中的应用。
方法
219例患者的1145条动静脉节段由不同经验程度的检查者分别采用CCDS和血管造影进行成像。计算敏感性、特异性和准确性。
结果
对于动脉节段——从锁骨下动脉至前臂远端动脉，敏感性为90%，特异性为99%。血液透析动静脉内瘘血管病变检测的敏感性为89%，特异性为95%。
结论
除评估手部动脉和中心静脉外，CCDS可能能够取代手臂的诊断性血管造影。
