目的探讨超声诊断移植肾动脉狭窄的临床应用价值。方法回顾性分析20例移植肾动脉狭窄的二维及多普勒超声特点,并与移植肾CT动脉造影(CTA)或数字减影血管造影(DSA)相对照。结果 20例经CTA或DSA确诊的移植肾动脉狭窄(重度4例,中度16例)中,超声诊断移植肾动脉狭窄17例,其中重度4例,中度13例;20例中漏诊3例,均为中度狭窄。两种方法移植肾动脉狭窄确诊率差异无统计学意义(P>0.05)。结论彩色多普勒超声检查是诊断移植肾动脉狭窄的首选方法,可以指导临床进一步诊断和治疗。
Objective To investigate the clinical value of ultrasonic diagnosis of renal artery stenosis. Methods Two-dimensional and Doppler ultrasonographic features of 20 patients with renal artery stenosis were retrospectively analyzed and compared with CT angiography (CTA) or digital subtraction angiography (DSA). Results Twenty cases of transarterial stenosis were diagnosed by ultrasonography in 20 cases of renal artery stenosis (severe 4 cases, moderate 16 cases) diagnosed by CTA or DSA, of which 4 cases were severe and 13 cases were moderate; 3 cases were missed in 20 cases , Are moderately narrow. There was no significant difference between the two methods in the diagnosis of renal artery stenosis (P> 0.05). Conclusion Color Doppler ultrasonography is the first choice for the diagnosis of renal artery stenosis. It can guide clinical further diagnosis and treatment.
