To reveal the intraorganic arterial anastomoses we studied arterial lobar architectonics and the topography of true hepatic interlobar borders. 23 samples of cadaveric liver were studied with the use of preparating technique, separate injecting colouring solutions, microfocus angiography, and transparenchymal sections. When the arterial bed of the liver was injected with colouring solutions or radiocontrast agents, in 21 cases the agents were visualized only within the injected lobe. In 2 observations, an extraorgan arterial anastomosis was detected between the branches of the hepatic artery in the gates of the liver. The investigation revealed that the anatomical and surgical concepts of the inter-lobar hepatic border do not coincide according to the arterial sign; macroscopically visible inter-lobar intraorganic arterial anastomoses are normally absent, which indicates the relative isolation of hepatic lobes. |
