Systematisation of the Arteries in the Splenic Hilus

Abstract

156 abdominal preparations were explored by arteriography, corrosion and dissection. Within the meanders of the splenic artery a basic pattern can be traced. The division of the artery can easily be summarized by introducing the term of a truncus lienogastroepiploicus. The short gastric arteries are always present, and usually they are longer and more important than may appear from their name. In nearly half of the preparations (52%) an artery for the extremitas lienalis posterior is found; an artery for the extremitas lienalis anterior is very exceptional. A posterior gastric artery can be identified (36%) but it must be distinguished from several other vessels. The arteria colli pancreatis (for the neck of the pancreas) is a constant vessel that may have a superior (usually arteria lienalis) or an inferior origin (arteria mesenterica superior). It commonly supplies the transverse pancreatic artery and often the prepancreatic arcade. The arteria corporis pancreatis, too, is a constant artery. The pancreatic tail is thoroughly irrigated by usually more than one arteria caudae pancreatis. An important part of the greater curvature is not accompanied by the left gastroepiploic artery, but is supplied by the arteriae gastricae breves.

The unrecognized posterior gastric artery: a potential cause of surgical complications in pancreas transplantation

“…It usually arises from the cranial border of the proximal half of the splenic artery, measuring about 1.5–3 mm in diameter (4–7). The posterior gastric artery courses upward posteriorly in an oblique direction, to the parietal peritoneum of the lesser sac, where it raises a fold before supplying the proximal posterior gastric wall (4–11). In some cases, it may also supply the distal esophagus and the spleen (forming an upper polar splenic artery) (6, 12).…”

A Case Report; Trilobular Spleen?

“…Mikhail and Garcia-Porrero reported that splenic artery could give off one superior polar, one to three inferior polar, two (superior, inferior) or three (superior, medial, inferior) terminal (primary) segmental branches (Mikhail, 1979;Garcia-Porrero, 1988). Vandamme and Redmond reported that splenic artery was divided into one superior polar, two central (superior, inferior) and one inferior polar branches and each of them supplied their segments of spleen (Vandamme et al , 1986;Redmond et al, 1989).…”

Safe Partial Embolization of the Splenic Artery in Accordance to Its Last Pancreatic Branch

“…This could be explained by slight tissue shrinkage produced by formalin fixation in cadavers (Larsen et at., 2003). Vandamme and Bonte (1986) described the splenic artery to be composed of four anatomical divisions, including suprapancreatic, pancreatic, prepancreatic and prehilar segments. Moreover, Waizer et al (1989) reported the lengths of these splenic arterial segments to be 2.5, 10.5,2.5 and 1.5 em respectively.…”
