Pulsatile portal venous flow - Radiopaedia

01-12-2018 · A pulsatile portal venous flow pattern can result from both physiological and pathological causes. In well subjects mild pulsatility, or in rare situations, even marked pulsatility has been described, particularly in thin subjects, with a venous pulsatility index of 0.5 with an inverse correlation to body mass.

Biphasic portal vein Doppler trace - Radiopaedia

02-01-2018 · A normal portal vein Doppler trace should be monophasic with a little variation in maximum and minimum velocity, with no reversal of flow. In this particular case, when the line drops below the 0 cm/s level, there is reversal of flow. 1 article features images from this case Pulsatile portal venous flow 1 public playlist

Hepatic vein and portal vein Doppler ultrasound of ...

Results: Maximum flow velocities of both right hepatic vein and main portal veins were lower in group III compared with group I and group II (p 0.05). On the basis of hepatic vein and portal vein waveforms, the incidence of biphasic pattern was prominent in group II (p 0.05) whereas the monophasic pattern was prominent in group III (p 0.05).

What is the normal size of the portal vein? – handlebar ...

How is portal vein flow measured? Portal vein blood flow could then be calculated as Q, = V x ([email protected]/4) x 60, where Q, is the PVF as measured by the Doppler technique (in milliliters per minute) and D is the portal vein diameter (in centimeters). What is normal Hepatopetal flow?
