[Features of the development of the arteries of the human liver and their practical significance].
By means of roentgenography and preparation methods 145 specimens of the hepatic arteries filled with roentgenopaque latex have been studied. An essential individual changeability is peculiar for the celiac trunk structure and for formation of the hepatic arteries. A "typical" structure of the celiac trunk is observed in 66%. In other cases either "noncompleteness" of the celiac trunk, or increasing number of the branches up to 4-6 are observed. As a rule, the common hepatic artery gets of the celiac trunk (93%), but sometimes it can take its origin from the aorta, the superior mesenteric artery and some other sources (7%). The hepatic artery proper only in 73% divides into the right and left branches, in other observations the latter have their independent formation. It is necessary to distinguish the independent separation of the right and left lobar hepatic arteries from some sources and presence of additional arteries. The additional arteries are the branches that are formed from any arteries when there is present the hepatic artery proper, or substituting it independent right and left branches. The additional arteries appear from the left gastric, superior mesenteric, gastro-duodenal arteries, from the aorta, the right renal artery and other sources. The peculiarities of formation of the hepatic arteries discussed can be used in clinical practice and can make the terminology more precise.
