Hepaticography

Hepaticogram: concept and principles.

Hepatitis is a serious liver disease that is accompanied by severe symptoms and can also lead to serious complications. A study such as a hepaticogram will help to understand the cause and course of hepatitis. In the article we will analyze how this study works, what analyzes

Hepaticogram is a medical term used to describe a method of medical examination of the blood circulation in the liver or hepatocytes of a patient. It is performed using angiography of the liver vascular system. This diagnostic method is more informative in comparison with traditional methods of clinical examination of the liver.

The purpose of liver angiogradation is to carry out an objective assessment of blood flow and vascularization of the liver to determine the shape, size, configuration, structure of the liver parenchyma, to establish the characteristics of the course of the pathological process, and the presence of hepatic hypoxia. To obtain angiographic pictures, the technique of introducing radiocontrast substances through a catheter into the body is used.

Abstract: Hepatography is a graphic display of the hepatic system.

Hepatography includes a number of graphic methods reflecting the anatomical and functional state of the liver. These include echolography, chronocholegraphy, radioisotope hepatography, angiography, duplex ultrasound examination of blood vessels, etc. In newborns (especially in the early neonatal period) to determine the structural composition and function of the liver more accurately than in adults. For comparison, the nature of the location of the liver tissue relative to its shape is assessed, large branches are noted, especially the size of the lobar and segmental blood supply. Liver cirrhosis is characterized by thinning of its parenchyma on the side corresponding to scar changes. The presence of small fibrous nodes (nodular cirrhosis of the liver) is noted mainly to the right of the middle of the organ. A significant decrease in the echogenicity of parenchymal tissue should be considered a sign of portal cirrhosis. Determining the vascular pattern and features of blood flow helps to assess the structure of the liver and its functional state. The results of the study make it useful in diagnosing tumor changes. Congenital liver anomalies are almost always accompanied by portal hypertension syndromes with mechanical jaundice, increased venous pressure and dilated splenic veins. Liver damage occurs due to abdominal trauma, wounds, chemical poisoning and is accompanied by an increase in blood cells in the portal circulation, disturbances in the synthetic function of the liver and general metabolism. Graphic methods allow us to identify their signs. Deformations of the posterior edge of the medial surface at the level of the right kidney and lower parasternal line, protrusion of the intestine beyond the liver, enlargement of the gallbladder
