The importance of supporting the spleen with blood is enormous especially from the surgical point of view. The main vessel of spleen is the splenic artery. In this study we would like to extend current knowledge of anastomoses between the splenic artery and surrounding arteries. Seven donor bodies of both sexes were used for detailed dissection. We were concerned with both the intraperitoneal and extraperitoneal anastomoses. In another 100 donor bodies, the relationship between the spleen and the anterior surface of the posterior body wall was studied. The superficial anastomoses were found mainly in the peritoneal duplications. They were the short gastric arteries; the epiploic branches of the left gastroepiploic artery; branches of the middle and left colic arteries and arteries from the region of the pancreatic tail. Deep anastomoses were found between the spleen and the parietal branches of the aorta, i.e. the superior and inferior phrenic arteries and the arteries of the anterior surface of the posterior body wall: the posterior intercostal artery and lumbar arteries. Authors also expect small anastomoses in 40-50% of spleens that lie directly on the anterior surface of the posterior body wall. Our findings correspond with the clinical observations that after ligation of the splenic artery necroses in the spleen do not occur.
从外科角度来看，补血养脾的重要性极大。脾的主要血管是脾动脉。在本研究中，我们希望拓展关于脾动脉与周围动脉之间吻合情况的现有认知。使用了7具男女供体尸体进行详细解剖。我们关注了腹膜内和腹膜外的吻合情况。在另外100具供体尸体中，研究了脾与后体壁前表面之间的关系。浅表吻合主要见于腹膜折返处。它们是胃短动脉；胃网膜左动脉的网膜支；中结肠动脉和左结肠动脉的分支以及胰尾区域的动脉。在脾与主动脉的壁支之间发现了深部吻合，即膈上动脉、膈下动脉以及后体壁前表面的动脉：肋间后动脉和腰动脉。作者还预计，40%至50%直接位于后体壁前表面的脾脏存在小的吻合。我们的研究结果与临床观察结果相符，即脾动脉结扎后脾脏不会发生坏死。
