I prepared 20 white rats of first and second months with the purpose to study shape and topography of lymph nodes (LN) in the basin of coeliac artery. Usually it divides into two end branches: the right - hepatic artery, the left - gastrosplenic artery. I found one small LN with oval shape on caudal side of gastrosplenic artery, near end of splenic vein and two LN with such shape and sizes along hepatic artery, in different position about hepatic portal vein. Sometimes hepatic LN was unpaired and large as ileocaecal LN. I found two groups of LN along splenic artery and vein, near dorsal border of pancreas:
the dexter two LN, large, with shape of bean or «coffee bean» - pancreatic LN. They lie on dorsal side of greater curvature of stomach, near pylorus («caudal gastric» LN). After withdrawal of stomach these LN remain on the dorsal border of pancreas, about splenic vein. The body of pancreas separates pancreatic LN (at cranial side of pancreas) and central mesenteric LN (at the caudal side);
the left two LN, oval, in 2-3 times lesser, than the dexter, - splenic LN. They lie on the place of curve or bifurcation of body of pancreas (crossing into tail), about splenic hilum, between its two cranial veins.
Tail of pancreas ajoins to visceral surface of caudal part of spleen, and between splenic LN and cranial part of spleen is determined gastrosplenic ligamentum. Thus, 6-7 LN are situated in basin of coeliac artery of white rat, mainly in connection with hepatic portal (1-2) vein and splenic vein (5). Pancreatic and splenic LN enter in complement of gastrosplenic lymphatic circle. Two bundles of lymphatic vessels unite these LN: dorsal bundle passes onto greater curvature of stomach and ventral bundle acrosses pancreas.
