Arterial vascularization of the spleen in Merino sheep

Abstract

In this study, it is aimed to reach detailed information about the anatomy of arteries in the sheep spleen, which can be used as an example and model for the success of planned or emergency surgical interventions related to the spleen. In spleen injuries, the spleen may be divided into two or three parts, or it may be limited to cracks on the spleen. In particular, it is aimed to protect the organs that have been damaged by trauma recently. Operations such as splenectomy and splenography are surgical procedures that require good knowledge of the pathways of artery and its branches and segmentation of the spleen. In our study, 30 merino sheep spleens were used. Macroscopic findings were obtained from materials given colored liquid latex from arteria lienalis and preserved in formaldehyde. In addition, artery patterns of the spleens obtained by the corrosion cast method were also used. Scanning electron microscopic images were taken and evaluated. When 30 spleens were examined in the study; arteria lienalis, we examined were divided into two main branches as arteria ventralis and arteria dorsalis. Arteria medialis extending to the avascular region was detected in 2 of 30 spleens. In only 1 of the 30 spleens, an accessory artery was observed that separated the arteria ventralis. It was examined that arteria centralis originated from arteria trabecularis. It was determined that arteriola penicillaris, which has smaller diameter arteries and where the circulation takes place, originates from arteria centralis. This is a macroscopic and scanning electron microscopic study examining the arterial distribution of the spleen in high merino sheep population in Turkey. With this aspect of the study, it is aimed to contribute to the literature.
