Color Doppler ultrasonography showed hepatofugal
flow in this vascular channel.
The umbilical vein however has been speculated to spontaneously recanalize during portal hypertension to serve as a hepatofugal
, decompressing collateral .
Esophageal metastasis from HCC is presumed to be caused by tumor thrombi invading through the portal system and dissemination from the hepatofugal
portal blood flow to the gastrointestinal tract [4, 19].
Arterial portography is another method of navigation, which requires intra-arterial injection of contrast, although visualization of the PV can be suboptimal, particularly if there is hepatofugal
PV flow (26).
Liver Grade 1 (chronic liver disease): coarse echotexture, +- irregular surface, +- blunt or rounded margin, portal vein caliber 13 mm and a hepatopetal velocity of <15 cm/sec or a hepatofugal
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)).
We postulate that DENV infection of the liver might affect the sinusoidal endothelial or Kupffer cells in a way that causes obstruction to the hepatic sinusoidal capillary lumen resulting in decreased portal venous blood velocity and flow to the liver and, when severe, shunting of portal blood away from the liver (hepatofugal
It was hepatopetal in 46 (92 Percent) and hepatofugal
in 4(8 Percent) patients.
Pelvic angiography studies have revealed that most of the submucosal portosystemic communications (PSCs) of RVs have hepatofugal
inflow to intrinsic rectal venous plexus (IRVP) through the wall of rectum by branches of superior rectal vein (SRV): a tributary of inferior mesenteric vein .
Na hipertensao portal em grau mais avancado, tambem e possivel detectar fluxo hepatofugal
ao Doppler, o qual e considerado anormal em qualquer segmento da veia porta.
In these patients, the lungs and abdominal lymph nodes are the most common sites of metastasis possibly due to hepatofugal
portosystemic shunting (ie, flow directed away from the liver to the systemic circulation) induced by splenic vein obstruction or to the presence of aggressive features of the primary carcinoma.
Air in portal venous radicals assumes a peripheral, subcapsular location within the liver parenchyma, reflecting the direction of portal venous flow, while air in the biliary tree will have a more central location in the porta hepatis as a consequence of hepatofugal
