Disease (NS-CLD)###Portal vein###Calibre <13mm, hepatopetal velocity 15 cm/sec
Portal vein###Calibre 13mm, hepatopetal velocity 12 cm, +- splenic varices
1,4-6 Anatomically, portal vein (PV) is intricately related to the liver architecture because it carries deoxygenated but nutrient rich blood from the gastrointestinal tract towards liver in a hepatopetal
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.
The portal venous phase of superior mesenteric vein (SMV) angiography demonstrated hepatopetal flow into the liver, no arteriovenous communication, and a large umbilical vein decompressing the portal system.
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.
3] This channel decreases the pressure gradient of the portal vein, resulting in normal hepatopetal
blood flow into the liver.
Hepatic veins show normal triphasic waveform (type I) with two hepatofugal and one hepatopetal
(retrograde) velocity peaks and abnormal biphasic waveform (Type II) without retrograde flow phase and without reduced oscillation, biphasic with reduced oscillation (type III) and flat (monophasic) waveform ( type IV).
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.
Normalmente, o fluxo e hepatopetal
(isto e, vem em direcao ao figado).
