Doppler ultrasound is a well established method for assessment of the portal venous system to detect the direction of portal blood flow. It is helpful for non-invasive diagnosis of intra-abdominal portosystemic shunts, especially in patients with cirrhosis. Less attention has been paid to other influences on portal venous flow, e.g. tricuspid regurgitation, increased hepatic out-flow resistance, respiratory cycle. The aim of this pictorial review is to describe the spectrum of physiological and pathological Doppler ultrasound flow patterns in the portal venous system.
多普勒超声是一种成熟的评估门静脉系统以检测门静脉血流方向的方法。它有助于对腹腔内门体分流进行无创诊断，尤其是对肝硬化患者。人们较少关注对门静脉血流的其他影响因素，例如三尖瓣反流、肝流出阻力增加、呼吸周期。本图像综述的目的是描述门静脉系统中生理和病理多普勒超声血流模式的范围。
