[Variants in the number and size and the topography of the lumbar lymph nodes in the regional of the liver in the human adult].

By means of interstitial and direct injections of the lymphatic bed of the liver and gall bladder, their regional lymph nodes from the lumbar group have been studied in 63 corpses of mature persons of both sex. The hepatic lymph vessels flow into the lumbar lymph nodes in 73% of cases. Only the postaortal nodes (situating behind the abdominal part of the aorta) do not take the hepatic lymph nodes. The number of the hepatic regional lumbar lymph nodes varies from 1 to 6, and their size is within the limits 2X2--30X10 mm. In 13% of cases intercalated lumbar lymph nodes have been revealed (6X4 mm in size), they are situated along the pathway of the visceral surface of the lymph vessels (of the right hepatic lobe) running towards large intermediate lumbar lymph nodes.
