目的分析超声诊断肾动脉狭窄的临床价值,为中老年肾动脉狭窄的有效诊断提供借鉴和指导。方法选取2014年4月至2016年8月于医院诊治的疑似肾动脉狭窄患者44例,对其88条肾动脉同时进行彩色多普勒超声及血管造影检查,观察两种诊断方式的诊断情况,评估两者的准确度。结果在88条肾动脉主干中,血管造影技术检测检测结果为80条肾动脉主干及8条副肾动脉。超声检查检出80条肾动脉主干和1条副肾动脉,漏诊7条,漏诊率7.95%。其中38条为70%以上狭窄(重度狭窄),42条为正常或69%以下狭窄(中、轻度狭窄)。结论肾动脉超声诊断技术用于诊断肾动脉狭窄,具有无创、费用少等优势,且与血管造影的符合率较高,是一种方便、快捷的检查手段。
Objective To analyze the clinical value of ultrasonography in the diagnosis of renal artery stenosis and provide references for the effective diagnosis of renal artery stenosis in middle-aged and elderly people. Methods Forty-four patients with suspected renal artery stenosis who were diagnosed and treated in our hospital from April 2014 to August 2016 were enrolled in this study. 88 renal arteries were examined by color Doppler ultrasonography and angiography at the same time. The diagnosis of the two diagnostic methods were observed, Assess the accuracy of both. Results Of the 88 renal arteries, the results of angiography were 80 renal arteries and 8 accessory renal arteries. Ultrasound examination detected 80 renal artery and 1 renal artery, missed 7, missed diagnosis rate of 7.95%. Of which 38 were more than 70% stenosis (severe stenosis), 42 were normal or 69% stenosis (moderate stenosis). Conclusion The diagnosis of renal artery stenosis with renal artery ultrasound diagnosis is noninvasive, inexpensive and has a high coincidence rate with angiography. It is a convenient and quick examination method.
