摘要
目的 探讨经静脉声学造影诊断肾动脉狭窄的可行性。方法 对 9例临床疑诊肾动脉狭窄患者进行了经静脉声学造影检查 ,并与DSA结果对比。结果 声学造影显示 2例肾动脉无彩色血流信号 ,ECT扫描肾脏不显影 ;5例肾动脉中段或起始段彩色血流束局限性细窄 ,其宽度 0 .30～ 0 .38cm之间 ,而非狭窄处的宽度在 0 .83～ 1 .0 4cm之间 ;DSA显示彩色血流束细窄处有肾动脉狭窄存在。另 2例无肾动脉狭窄者 ,其血流束宽0 .70～ 0 .85cm。结论 经静脉声学造影剂能显著增强肾动脉彩色血流信号 ;通过观察造影增强后肾动脉彩色血流表现 ,能较准确地诊断肾动脉狭窄、闭塞等病变。
Objective To investigate the feasibility of diagnosis in renal artery stenosis (RAS) with intravenous contrast ultrasound. Methods Nine cases were examined with intravenous contrast ultrasound,who were suspected clinically to suffer from RAS. The results were compared with those of DSA.Results With the enhancement of intravenous ultrasound contrast agent, in 2 cases, color flow was not seen in renal arteries; their kidneys were also not visualized by ECT examination. In five cases the narrow of color Doppler flows in middle or beginning parts of renal arteries was scanned with the width of 0.30～0.38 cm, where renal artery stenosis was confirmatively found by DSA. But in another 2 cases with normal renal arteries, the blood flows were 0.70～0.85 cm wide. Conclusions The color Doppler flow signals could be significantly enhanced by intravenous contrast ultrasound , and it may be helpful to diagnose confirmatively the RAS through observing the blood flows in renal arteries by enhanced color Doppler ultrasonography.
