hepatic acinus

see liver acinus.

hepatic angle

the angle made by the caudolateral border of the caudate liver lobe on abdominal radiography.

hepatic arterioportal fistula

shunt between the hepatic artery and the portal vein.

hepatic atrophy and nodular regeneration

a disease of dogs, due to unknown cause but possibly a toxin, characterized by nodular regenerative hyperplasia and atrophy of severely fatty hepatocellular parenchyma and gradually developing, always fatal, liver insufficiency.

hepatic cell

hepatocyte.

hepatic cirrhosis

diffuse hepatic fibrosis associated with the formation of structurally abnormal, regenerative, parenchymal nodules. Initiated by hepatocyte necrosis.

hepatic coccidiosis

spoken of but recorded only once in a calf.

hepatic congestion

a common feature of congestive heart failure and other circulatory embarrassments of venous drainage of the liver; occurs also in anaphylaxis.

diffuse hepatic fibrosis

results from continued, chronic hepatic injury or the summation of repeated bouts of zonal necrosis; the resulting fibrosis links portal areas and hepatic venules and bisects liver lobules.

hepatic distomatosis

infection of the liver with flukes, e.g. Fasciola hepatica, Fascioloides magna, Metorchus conjunctus. See also fascioliasis.

hepatic diverticulum

hepatic injury

see hepatitis.

hepatic jaundice

jaundice caused by disease of hepatic parenchyma in contrast to hemolytic and obstructive jaundice.

hepatic lipidosis

see fatty liver.

hepatic microsomal enzymes

see microsomal enzymes.

hepatic necrosis

death of hepatic parenchyma which may be single cell (necrobiosis), or multicell in piecemeal, focal, periacinar, midzonal, periportal or paracentral locations. Massive necrosis refers to events in individual acini in which all hepatocytes are dead.

omphalogenic hepatic abscess

abscess resulting from infection of the umbilicus and direct vascular extension to the liver.

hepatic periacinar fibrosis

fibrosis limited to the zones around hepatic venules; a response to congestive heart failure or to intoxication.

hepatic photosensitization

see secondary photosensitization.

hepatic sinusoids

the intralobular vascular supply system; lined by endothelial cells and stellate macrophages.
