Anatomical and surgical relations of the splenic vessels and pancreas

Abstract

Anatomical and surgical relationship of the splenic vessels and the pancreas is important under the circumstances of modem organ and blood-flow preserving surgical principles.Topographical relationship of the splenic vessels and pancreas were studied on 36 corrosive and semicorrosive casts. The specimens were injected with autopolymerisant acrylic mass “PEДOHT-03®” and “ПPOTAKPUЛ-M®”. Soliddiquid ratio was 4:5 or 2:3, in order to obtain flexibility dibutylphtalat was added. In 93% cases a. lienalis was orientated inferior wit a length of 3-5 cm, being adherent to the pancreatic tissue. In 76% cases a. lienalis was located posterior to the mesopancreas, in 14% - on the superior pancreatic edge, while in 10% - intrapacreatic location was observed. In the distal portion of the pancreas, a. lienalis is isolated from the pancreatic tissue and located on superior pancreatic edge (80%) while in 20% - on the antero-superior pancreatic surface. The brunches of the splenic artery come across the splenic vein in oblique or vertical direction. The splenic vein was located in the middle and behind of the pancreatic body and tale in 17%, in 80% - closer to the superior pancreatic edge and in 3% closer to the inferior pancreatic edge. Splenic vein presents direct trajectory. Perivascular fibrous carcass is adherent to the pancreatic capsule by means of fibrous fibers, orientated along the pancreatic vessels. Conjunctive tissue is located between the perivascular fibrous carcass of the splenic vessels and the pancreas, fact that allows their separation during surgery. The established anatomical relation of the splenic vessels and the pancreas allows safe manipulations in caudal pancreatic resections, preserving the blood flow through the splenic vessels.
