  • Anatomy
  • In the widely used Couinaud (or "French") system of anatomy of the liver, the functional lobes are further divided into a total of eight subsegments based on a transverse plane through the bifurcation of the main portal vein. (wikipedia.org)
  • However, from a functional perspective (one that takes the arterial, portal venous, and systemic venous anatomy into account) the falciform ligament separates the medial and lateral segments of the left hepatic lobe. (wikipedia.org)
  • branches

  • The veins that run along the right region of the body through the heart and lungs are continued to be described to the best of Hippocrates' knowledge: "The other runs upward by the right veins in the lungs and divides into branches for the heart and the right arm. (wikipedia.org)
  • The classification system uses the vascular supply in the liver to separate the functional units (numbered I to VIII): Unit I is the caudate lobe and is situated posterior l and it may receive its supply from both the right and the left branches of portal vein. (wikipedia.org)
  • steatosis
  • Fatty liver disease (hepatic steatosis) is a reversible condition where large vacuoles of triglyceride fat accumulate in liver cells. (wikipedia.org)
  • Hepatic steatosis is considered reversible and to some extent nonprogressive if the underlying cause is reduced or removed. (wikipedia.org)
  • pulmonary veins
  • Anomalous pulmonary venous connection (or anomalous pulmonary venous drainage or anomalous pulmonary venous return) is a congenital defect of the pulmonary veins. (wikipedia.org)
  • Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which all four pulmonary veins are malpositioned and make anomalous connections to the systemic venous circulation. (wikipedia.org)
  • Normally, pulmonary veins return oxygenated blood from the lungs to the left atrium where it can then be pumped to the rest of the body). (wikipedia.org)
  • The four pulmonary veins are reconnected to the left atrium, and any associated heart defects such as atrial septal defect, ventricular septal defect, patent foramen ovale, and/or patent ductus arteriosus are surgically closed. (wikipedia.org)
  • A Partial anomalous pulmonary venous connection (or Partial anomalous pulmonary venous drainage or Partial anomalous pulmonary venous return) is a congenital defect where the left atrium is the point of return for the blood from some (but not all) of the pulmonary veins. (wikipedia.org)
  • systemic
  • Estimated hepatic blood flow calculated from systemic indocyanine green clearance correlates poorly with values obtained using hepatic vein catheterisation and the Fick principle, because of the variability in dye extraction (6). (thefreedictionary.com)
  • esophageal
  • The increased portal pressure causes increased filtration of vascular fluid with the formation of ascites in the abdomen and collateral venous flow through alternative veins leading to esophageal, gastric and rectal varices. (wikipedia.org)
  • segment
  • We've measured lumen diameters of portal vein in it's broad segment, vena lienalis, hepatic veins 2-3 cm above the place of their confluence in the vena cava inferior. (thefreedictionary.com)
  • The initial level set is able to evolve directly from the initial segmentation by spatial fuzzy clustering to segment lesions and hepatic vein. (alliedacademies.org)
  • The caudate lobe (posterior hepatic segment I, Spigelian lobe) is situated upon the postero-superior surface of the liver on the right lobe of the liver, opposite the tenth and eleventh thoracic vertebrae. (wikipedia.org)
  • vessels
  • The structure and location of hepatic vessels and their relationship to tumors and liver segments are of great interests to the surgeons for performing liver surgery planning [ 2 ]. (alliedacademies.org)
  • Each portal venule courses alongside a hepatic arteriole and the two vessels form the vascular components of the portal triad. (wikipedia.org)
  • These vessels ultimately empty into the hepatic sinusoids to supply blood to the liver. (wikipedia.org)
  • hepatocytes
  • Macroscopically, the liver has a pale and spotty appearance in affected areas, as stasis of the blood causes pericentral hepatocytes (liver cells surrounding the central venule of the liver) to become deoxygenated compared to the relatively better-oxygenated periportal hepatocytes adjacent to the hepatic arterioles. (wikipedia.org)
  • Each lobule is made up of millions of hepatic cells (hepatocytes) which are the basic metabolic cells. (wikipedia.org)
  • tumors
  • Measurement of liver volume and hepatic functional reserve as a guide to decision-making in resectional surgery for hepatic tumors. (springer.com)
  • however, the size of hepatic adenoma is considered to correspond to risk of malignancy and so larger tumors may be surgically removed. (wikipedia.org)
  • Abdomen
  • Measuring approximately 8 cm (3 inches) in adults, the portal vein is located in the right upper quadrant of the abdomen, originating behind the neck of the pancreas. (wikipedia.org)
  • balloon
  • The catheter has a deflated balloon at its tip, which the surgeon inflates once it's in the vein. (healthline.com)
  • The patient required double-balloon dilatation of the IVC simultaneously from the internal jugular vein and IVC. (springer.com)
  • acute
  • Acute disease might include infections such as oesophagitis, trauma caused ingestion of corrosive substances, or rupture of veins such as oesophageal varices, Boerhaave syndrome or Mallory-Weiss tears. (wikipedia.org)

  • Transverse image reveals dilated bile duct (red arrow) anterior to the portal vein (red arrowhead) resembling a double-barrel shotgun. (virginia.edu)
  • The mechanism(s) of low platelets after right hepatectomy is unclear and several hypotheses have been proposed including a decrease in thrombopoietin, and hepatic insufficiency resulting in relative portal hypertension following hepatic resection. (annalsofhepatology.com)
  • This anatomic course is important in the assessment of neonatal umbilical venous catheterization, as failure to cannulate through the ductus venosus results in malpositioned hepatic catheterization via the left or right portal veins. (wikipedia.org)
  • blood
  • Therefore, the evidence indicates that during histamine shock there was a shift of blood from the hepatic veins to the capillaries, rather than a pooling of blood in the splanchnic circulation. (ahajournals.org)
  • chest
  • When admitted to the hospital, and later in the ICU, he experienced severe chest pains, cardiac abnormalities, renal and hepatic toxicity, and nearly died. (wikipedia.org)
  • levels
  • Additionally, DPM down-regulated the mRNA and protein expression of jejunal Na(+)/glucose cotransporter, Na(+)/K(+)-ATPase and glucose transporter 2, and enhanced the activities as well as mRNA and protein levels of hepatic glycolysis enzymes (glucokinase, phosphofructokinase, private kinase and pyruvate decarboxylas E1).
