【摘要】 本文选择7例共13支经DSA确诊的肾动脉狭窄进行二维和多普勒超声心动图检查并与20例正常肾动脉比较。结果对照组肾动脉内径为5.0士0.5mm。收缩期最大血流速度为95.3士17.3cm/s。13支狭窄血管中共10支二维显示管腔局部狭窄(1.7～3.5mm),狭窄处血流速度明显增快(185～500cm/s)。结果表明:超声心动图对肾动脉狭窄诊断可靠。简单易行,可用于筛选和随访肾动脉狭窄。特别对我国常见的大动脉炎尤为适用。更多还原

【Abstract】 Seven patients with 13 renal arteries stenosis diagnosed by arteriography were examined with a combined 2DE and Doppler echocardiography, and compared with 20 patients without renovascular disease,The internal diameter and the peak systolic velocity of the control group were 5. 0±0. 5mm and 95. 3±17. 32cm/sec,respectively. Ten of the 13 renal artery stenoses were seen and Doppler flow recorded. The diameter and the peak systolic velocity of them were 1. 7-3. 5mm and 185 -500cm/sec, respectively. The results indicated that echocardiography is easy and reliable for diagnosis and screening of renal artery stenosis,especially in aortoarteritis which is the most common cause of renal artery stenosis in China.更多还原
