A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, [1] arranged in a clockwise manner starting from the caudate lobe.
The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
Liver diseases may be diagnosed by liver function tests–blood tests that can identify various markers. For example, acute-phase reactants are produced by the liver in response to injury or inflammation. The most common chronic liver disease is nonalcoholic fatty liver disease, which affects an estimated one-third of the world population. [59]
The liver scratch test can be used when other exam techniques used to approximate liver size are ineffective or unavailable [2] and is thought to be most useful if the abdomen is distended, too tender for direct palpation, the abdominal muscles are too rigid, or the patient is obese. [3]
Nausea and vomiting: These can be common symptoms of liver dysfunction. Confusion, drowsiness and slurred speech (hepatic encephalopathy): These symptoms can occur when toxins build up in the ...
The liver synthesises the bulk of lipoproteins. The liver is located in the upper right quadrant of the abdomen and below the diaphragm to which it is attached at one part, the bare area of the liver. This is to the right of the stomach and it overlies the gall bladder. The liver synthesises bile acids and lecithin to promote the digestion of ...
The US Food and Drug Administration has approved the first medication for a common form of liver inflammation called nonalcoholic steatohepatitis, or NASH, the agency said Thursday.
Anisokaryosis (or variation in the size of the nuclei) is common and often reflects tetraploidy and other degrees of polyploidy, a normal feature of 30-40% of hepatocytes in the adult human liver. [4] Binucleate cells are also common.
