HEPATIC VEIN [9 records]

Record 1 2025-10-30

English

Subject field(s)
  • Medical Instruments and Devices
  • Surgery
CONT

A number of perfusion devices are currently available. The principal components include a blood reservoir, centrifugal pump, oxygen concentrator, heat exchanger and a circuit which continuously pumps perfusate through the liver via the organ's inflow vessels(hepatic artery and/or portal vein) and recirculates this following drainage from the inferior vena cava.

OBS

A perfusion device is used to preserve an organ from the time it is removed from a donor until it is transplanted into a recipient.

French

Domaine(s)
  • Instruments et appareillages médicaux
  • Chirurgie
OBS

Un appareil de perfusion sert à préserver un organe entre le moment où il est prélevé chez un donneur et celui où il sera transplanté chez un receveur.

Record 2 2023-07-10

English

Subject field(s)
  • Morphology and General Physiology
  • Liver and Biliary Ducts
Universal entry(ies)
lobulus hepatis
Latin, see observation
CONT

The liver contains thousands of liver lobules, the functional unit of the liver... The liver lobules consist of a special arrangement of blood vessels and hepatic cells(hepatocytes). Note the central vein and the rows of hepatic cells that radiate away from the central vein.

OBS

lobule of liver; lobulus hepatis: designations found in the plural (lobules of liver, lobuli hepatis) in the Terminologia Anatomica.

Key term(s)
  • lobules of liver
  • lobuli hepatis

French

Domaine(s)
  • Morphologie et physiologie générale
  • Foie et voies biliaires
Entrée(s) universelle(s)
lobulus hepatis
Latin, see observation
CONT

Au centre de chaque lobule hépatique, une veine centrolobulaire collecte le sang qui quitte le lobule. Chaque lobule est constitué de milliers de cellules hépatiques. Elles sont organisées de façon complexe pour assurer d'une part la production et l'écoulement de la bile, et d'autre part les échanges avec le sang.

OBS

lobulus hepatis : désignation trouvée au pluriel (lobuli hepatis) dans la Terminologia Anatomica.

Record 3 2017-04-11

English

Subject field(s)
  • Vessels (Medicine)
DEF

Any of several large veins that drain blood from the liver into the inferior vena cava.

French

Domaine(s)
  • Vaisseaux (Médecine)
CONT

Les veines hépatiques évacuent le sang désoxygéné du foie vers le cœur.

Spanish

Campo(s) temático(s)
  • Redes vasculares (Medicina)
DEF

Las vías eferentes están representadas por las venas hepáticas que se originan de la vena sublobular y que confluyen entre sí formando troncos cada vez mayores, los cuales se dirigen hacia el borde posterior del hígado para desembocar en la vena cava mediante dos troncos: la vena hepática derecha y la vena hepática izquierda.

Record 4 2013-08-01

English

Subject field(s)
  • Vessels (Medicine)
CONT

Infection via the portal system(portal pyemia) : The infectious process originates within the abdomen and reaches the liver by entering the portal vein. Appendicitis and pylephlebitis are the predominant causes. However, any source of intra-abdominal abscess, such as acute diverticulitis, inflammatory bowel disease, and perforated hollow viscus, can lead to portal pyemia and hepatic abscesses.

Subject field(s)
  • Digestive Tract
DEF

The transverse fissure on the visceral surface of the liver where the portal vein and hepatic artery enter the liver and the hepatic ducts leave.

DEF

Dépression transversale de la face viscérale du foie constituant la voie de passage des principaux vaisseaux, conduits et nerfs hépatiques.

Record 7 1999-03-17

English

Subject field(s)
  • Medical Imaging
CONT

In the acute phase [of portal vein thrombosis], the portal vein is enlarged and has a CT attenuation value equal to that of unopacified blood on noncontrast images; it does not demonstrate central enhancement with contrast. Rarely, the thrombus may be of higher attenuation which is typical of freshly clotted blood. There may be segmental or focal decrease in hepatic enhancement to the segment(s) supplied by the occluded portal vein branches.

French

Domaine(s)
  • Imagerie médicale
CONT

Pour [pallier le risque de réalisation trop précoce de la spirale et de nombreux artefacts], Frush préconise l'utilisation d'une technique peu irradiante disponible sur certains appareils permettant de déclencher l'acquisition pour un seuil de rehaussement hépatique supérieur à 50 UH.

Record 8 1992-03-02

English

Subject field(s)
  • Digestive Tract
DEF

The indirect measurement of portal pressure by wedging of a percutaneously-introduced catheter in a hepatic vein radicle

French

Domaine(s)
  • Appareil digestif
OBS

Méthode indirecte de mesure de la pression portale (...) La méthode la plus utilisée est la mesure des pressions sus-hépatiques. Cette technique consiste à introduire un cathéter dans une veine sus-hépatique sous contrôle radiotélévisé et à bloquer le cathéter dans une veinule afin d'arrêter la circulation dans ce vaisseau. La pression mesurée est alors la pression sus-hépatique bloquée.

Record 9 1986-11-25

English

Subject field(s)
  • Liver and Biliary Ducts
CONT

The liver has been described as a collection of units called lobules, each of which contains, in its centre, a branch of the hepatic vein and, in its outer areas, a complex known as a portal tract. The portal tract includes a bile duct, a small branch of the portal vein, and a branch of the hepatic artery.

CONT

The hepatic lobules are small structural units of the liver enclosed by a thin layer of connective tissue formed by the branches of the Glisson's capsule. Where several lobules join, the connective tissue is more abundant and encloses a blood vessel, vein, nerves, lymphatic vessels, and small bile ducts. The structures together with the connective tissue form the "portal canals".

Key term(s)
  • portal space

French

Domaine(s)
  • Foie et voies biliaires
DEF

Territoire conjonctivovasculaire, de forme étoilée sur les coupes transversales, situé au contact de plusieurs lobules hépatiques et assurant le passage d'un rameau de l'artère hépatique et de la veine porte, d'un canal biliaire et de lymphatiques.

CONT

A la périphérie [du lobule hépatique], on trouve les "espaces portes", dont chacun contient une triade portale : un petit canal biliaire, une artériole, branche de l'artère hépatique, et une veinule, branche de la veine porte.
