Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray. [1] Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or ...
The caudate lobe is a separate structure which receives blood flow from both the right- and left-sided vascular branches. [5] [6] The Caudate lobe includes: (1) the Spiegel lobe; (2) the paracaval portion; and (3) the caudate process portion. The Spiegel lobe has its portal venous and biliary branches ramified mainly from the left-side tract.
The liver is grossly divided into two parts when viewed from above – a right and a left lobe – and four parts when viewed from below (left, right, caudate, and quadrate lobes). [16] The falciform ligament makes a superficial division of the liver into a left and right lobe. From below, the two additional lobes are located between the right ...
The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest. That is why the total liver blood flow is quite high, at about 1 litre a ...
The falciform ligament, visible on the front of the liver, makes a superficial division of the right and left lobes of the liver. From the underside, the two additional lobes are located on the right lobe. [2] A line can be imagined running from the left of the vena cava and all the way forward to divide the liver and gallbladder into two ...
Liver cirrhosis makes it hard for blood to flow in the portal venous system. [39] This resistance creates a backup of blood and increases pressure. [39] This results in portal hypertension. Effects of portal hypertension include: Ascites is a build-up of fluid in the peritoneal cavity in the abdomen [40] An enlarged spleen in 35–50% of cases [6]
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .
Increased blood pressure in the portal vein, called portal hypertension, is a major complication of liver disease, most commonly cirrhosis. [7] A dilated portal vein (diameter of greater than 13 or 15 mm) is a sign of portal hypertension, with a sensitivity estimated at 12.5% or 40%. [ 8 ]
