We investigated the correlations in incidence and anatomy of 2 splenic artery branches, the Posterior Gastric Artery (PGA) and the Superior Polar Artery (SPA). In the literature these 2 branches were never described on one and the same splenic artery. We studied the splenic arteries of 126 corpses and found a cranio-sinistrally directed branch of the splenic artery in 76.2%. It appeared as a PGA (only stomachial supply) in 27.7% and as a SPA (only splenic supply) in 3.27%. In the most cases we detected an intermediate-type--we called it "gastrosplenic artery = GSA"--having a posterior gastric and a superior polar branch simultaneously. Such a "gastrosplenic artery" leaves the main trunk of the splenic artery in its middle segment in cranio--sinistral direction and falls apart into a posterior gastric and a superior splenic branch both with various differences in caliber. All these variations are described, nomenclature and the functional and surgical importance of these findings are discussed.
我们研究了脾动脉的两个分支，即胃后动脉（PGA）和脾上极动脉（SPA）的发生率及解剖结构的相关性。在文献中，从未在同一根脾动脉上描述过这两个分支。我们研究了126具尸体的脾动脉，发现76.2%的脾动脉有一个由头侧向左侧走行的分支。其中27.7%表现为胃后动脉（仅供应胃），3.27%表现为脾上极动脉（仅供应脾脏）。在大多数情况下，我们检测到一种中间类型——我们称之为“胃脾动脉 = GSA”——同时具有胃后支和脾上极支。这种“胃脾动脉”在脾动脉主干的中段以头侧向左侧的方向发出，然后分成胃后支和脾上支，两者管径各不相同。本文描述了所有这些变异情况，并讨论了这些发现的命名法及其功能和手术意义。
