  • Diagnostic sonography SCRS: Portal vein ultrasound anatomy variations
    The portal venous system can be recognised on ultrasound as a tubular structure with echogenic walls that enters the liver together with the hepatic artery (HA) at the level of the hepatic hilum (a), and reaches the more distal liver segments
  • Portal vein | Radiology Reference Article | Radiopaedia. org
    Immediately before reaching the liver, the portal vein divides in the porta hepatis into left and right portal veins The right portal vein divides into anterior (supplying segments 5 and 8) and posterior (supplying segments 6 and 7) branches
  • Portal Vein Doppler – Sonographic Tendencies
    When the portal vein enters the liver it bifurcates into right and left main branches The right portal vein bifurcates into an anterior and posterior branch which feed segments 5, 6, 7 and 8 respectively, whereas the left branch feeds segments 2, 3 and 4
  • Typical and atypical portal vein Doppler ultrasound spectrums . . . - EPOS™
    Fig 3: Normal portal vein (a) B-mode ultrasound shows normal appearance of right portal vein with anechoic lumen (b) Colour Doppler demonstrates normal hepatopetal flow (c) Spectral Doppler reveals normal portal vein waveform with mild undulation and normal velocity (17 2 cm sec)
  • Ultrasound Evaluation of the Portal and Hepatic Veins
    Flow is in the opposite direction (red) in the hepatic artery, which lies anterior to the main portal vein Reversed flow in the portal vein usually indicates relatively severe PHT and is a late finding
  • EUS Tutorial: How to Trace the Right Portal Vein and Its Branches
    You’ll learn step-by-step how to identify, follow, and differentiate the anterior and posterior divisions of the right portal vein from the main portal trunk, using real-time endoscopic
  • Hepatobiliary Ultrasound - Radiology Key
    The common hepatic duct descends to the right of the hepatic artery and anterior to the portal vein Typically, the right hepatic artery passes posterior to the common hepatic duct, but an important variant is passage of the right hepatic artery anterior to the duct
  • Anatomic Variations of the Right Portal Vein: Prevalence, Imaging . . .
    The right portal vein – which is most commonly accessed during TIPS – is subject to various anatomic variants that may potentially impact procedure success This pictorial essay characterizes the anatomic patterns of the right portal vein branching in terms of type and frequency based on case series review
  • Ultrasound of the Hepatoportal Circulation | Thoracic Key
    Normal Doppler waveform of the portal veins demonstrates continuous antegrade flow toward the liver with a mildly undulating pattern Flow is affected by respiration and cardiac pulsatility, although the effect is normally mild
