In stenosis of a segmental branch or among multiple renal arteries, Doppler sampling of intrarenal arteries in the upper, mid and lower poles demonstrates strikingly different waveform patterns that might otherwise be overlooked. We report a case of segmental branch renal artery stenosis in which a pulsus parvus et tardus waveform was observed in a segmental branch of a renal artery. In this case, systematic analysis of Doppler waveforms of intrarenal arteries at more than three different locations facilitated a rapid and confident diagnosis of segmental branch renal artery stenosis.
在节段性分支或多支肾动脉存在狭窄时，对肾上极、肾中极和肾下极肾内动脉进行多普勒采样，可显示出截然不同的波形模式，否则这些模式可能会被忽视。我们报告一例节段性分支肾动脉狭窄病例，在该病例中，在一支肾动脉的节段性分支中观察到了小慢波波形。在该病例中，对肾内动脉在三个以上不同位置的多普勒波形进行系统分析，有助于快速且准确地诊断节段性分支肾动脉狭窄。
