The splenic artery in lienal hilum region

Abstract

Abstract Background: To know the structural and topographic aspects of the blood vessels of the spleen is an interest, particularly at present stage when surgical interventions are practiced more and more preserving mostly the injured organs because of the abdomen’s traumatisms. Splenography is often considered to be dangerous because of the risk of hemorrhage from the tissues of the sutured spleen. This danger can be reduced by improvement of surgical technique and by cognition of collateral ways of the blood circulation. Material and methods: The types of ramification of the splenic artery at the level of lienal hilum were determined on complex of organs by tiny macroscopic dissection and corrosion. The results have been analyzed statistically depending on the age and the sex of the patients. Results: In men, the ramification of the lienal artery in the hilum with a sharp angle (22.5 ± 3.96%) as well as with an obtuse angle (12.6 ± 3.15%), came about more often in age group VIII1 . In women the greatest frequency of the lienal artery ramification was found under an obtuse angle in the IX age group (20.0 ± 4.47%), but with a sharp angle the X age group (17.5 ± 4.25%). The results achieved in men and women of different age group were of a significant difference: p < 0.01 (for the ramification of the vessel under an obtuse angle) and p < 0.05 (for the ramification of the vessel under a sharp angle). Conclusions: Both structurally and topographically, the lienal artery is highlighted by a large range of variations in the region of the hilum. Key words: lienal artery, ramification changes, a. lienalis.
