先天性肾动静脉瘘二维超声通常无明显异常或者肾内无回声团;CDFI模式下发现肾内五彩镶嵌的彩色血流信号;DOPPLER高速、低阻、毛刺频谱。在有不明原因反复血尿的患者、高血压的患者(特别是年纪较轻,多种降压药效果不佳的);要有意识的用CDFI模式去检查和排除肾动静脉瘘。肾内的无回声团应常规CDFI检查。

体格检查:头顶皮肤局限膨隆,呈酒红色,皮温高,扪及震颤。 超声:局限头顶皮肤增厚,边界不清,皮肤层内及皮下见扭曲的管状无回声;CDFI:管状无回声内见丰富血流信号;DOPPLER:测多出血流均呈高速低阻频谱。Vmax2.56m/s,RI0.34。 Schobinger临床...
在这项研究中,研究人员主要运用了以下几种关键技术方法:一是通过经颅多普勒(Transcranial Doppler)检测微栓子信号,以此判断是否存在右向左分流;二是利用经胸超声心动图(Transthoracic echocardiogram)观察心房和心室内有无气泡,辅助判断分流情况;三是借助肺血管造影(Pulmonary arteriography)确定 PAVF 的位置和形态;四是运用...
