ROC curve showed area under the curve to be 0.917 with p13 mm, hepatopetal
velocity of 1.0 was considered to be abnormal.
The chronic PVT may result in main portal vein occlusion and cavernous transformation, while the obstructed portal vein is replaced by a network of hepatopetal
flow was noted in the main, right, and left portal veins.
Abdominal ultrasonography was performed to exclude multiple focal liver lesions, and various ultrasound-based parameters were recorded (presence of umbilical or pararenal shunt, portal vein width, portal blood flow mean peak velocity, portal blood flow mean velocity, portal blood flow type (hepatopetal
versus hepatofugal), hepatic vein blood flow type (triphasic, biphasic, or monophasic), hepatic vein damping index, and splenic vein size (width, length, and thickness)).
(6) The normal waveform demonstrates 2 hepatofugal peaks reflecting right atrial filing during ventricular systole and diastole, followed by a hepatopetal
peak from retrograde flow into the hepatic veins during atrial contraction.
It was hepatopetal
in 46 (92 Percent) and hepatofugal in 4(8 Percent) patients.
We describe a case of pre-sinusoidal PH whose treatment with DSRS rather than TIPS reduced the long term complication of shunt thrombosis associated with TIPS, and maintained hepatopetal
nutritional blood flow to the liver.
O fluxo da veia porta nos caes e hepatopetal
, ou seja, em direcao ao figado, ao passo que o fluxo hepatofugal, isto e, em direcao oposta ao figado, e considerado anormal em qualquer segmento deste vaso.
During the procedure, the radiologist places an expandable metallic shunt percutaneously into the liver to create a channel between a hepatic vein and a portal vein. This channel decreases the pressure gradient of the portal vein, resulting in normal hepatopetal
blood flow into the liver.
###Disease (NS-CLD)###Portal vein###Calibre <13mm, hepatopetal

It is an established fact that the normal hepatopetal
flow in portal vein is affected in diseased individuals but it can also vary considerably in normal individuals making it a strong predictor for future portal vein diseases.236
Normalmente, o fluxo e hepatopetal
(isto e, vem em direcao ao figado).
