目的：探讨血管内超声筛查动脉粥样硬化性肾动脉狭窄的价值。方法：选取行肾动脉造影的患者，进一步进行血管内超声检查，观察肾动脉斑块的特点，比较肾动脉造影与血管内超声检查结果之间的相关性，探索血管内超声检查是否增加X线曝光时间。结果：在动脉粥样硬化性肾动脉狭窄的患者中，血管内超声检查可以获得稳定的肾动脉全程图像，能描述肾动脉斑块的解剖学信息，血管内超声扫查结果与造影结果具有良好的相关性，能发现造影所不能发现的问题，可以作为肾动脉造影的重要补充，血管内超声检查未显著增加术中X线暴露时间。结论：血管内超声可以实现动脉粥样硬化性肾动脉狭窄的常规筛查，是肾动脉造影的重要补充，不显著增加X线暴露时间。

Objective:To evaluate the value of screening the atheroscle-rotic renal artery stenosis ( RAS ) with intravascular ultrasound ( IVUS ) . Methods:Patients undergone renal artery angiography received further in-spection of IVUS by which the properties of the renal artery plaque was investigated.The findings were compared for the relationship between re-nal artery angiography and IVUS as well as whether the IVUS examination had increased the X-ray exposure time.Results: In patients with athero-sclerotic RAS,IVUS enabled better exposure of stable renal artery picture and definition of the anatomic configuration of the artery plaque , and it still produced comparable findings with that did by the angiography .In addition,IVUS examination did not significantly increase the intraopera-tive X-ray exposure time.Conclusion: IVUS may be used for regular screening of atherosclerotic RAS and serve as an assistant means for renal artery angiography without increase the X-ray exposure time.
