A Macroanatomical Study on Coronary Veins in Southern Karaman Sheep

Abstract

Objective: This study aimed to reveal the coronary veins and their branches that provide venous drainage of the heart in Southern Karaman sheep. Material-Method: Eight Southern Karaman sheep’s heart tissues were used in the study. Latex injection techniques were used to determine the coronary veins and their branches providing venous drainage of the heart. Result: In the study, vena cordis magna, vena cordis media, and vv. cordis dextra was observed as venous drainage providing vessels. The vena cordis magna begins in the lower third of the sulcus interventricularis paraconalis, called vena interventricularis paraconalis. This vein reaches the sulcus coronarius and continues as vena circumflexus sinister. Vena cordis media was named as vena interventricularis subsinosus in sulcus interventricularis subsinosus. The vv. cordis dextra was responsible for the venous drainage of the facies atrialis of the heart. Conclusion: In the evaluation of the study findings, it was determined that the coronary veins and their branches of Southern Karaman were mainly similar to other sheep breeds in the literature. Still, there are some anatomical differences, such as the existence of semicircumflexa dextri.
