Comparative Macroanatomic Investigations of the Venous Drainage of the Heart in Akkaraman Sheep and Angora Goats

This study was carried out to evaluate the origin, course and terminations of the cardiac veins in Akkaraman sheep and Angora goats. These vessels are the great cardiac, left marginal, middle cardiac, right cardiac and smallest cardiac veins. For this purpose, latex was injected into the jugular vein of eight adult healthy Akkaraman sheep and Angora goats. These veins were dissected. It has been shown that the middle cardiac vein and great cardiac veins coursed with the branches of the coronary arteries and that they were anastomosed with each other. The venous blood from the great cardiac vein and middle cardiac veins emptied into the right atria via the coronary sinus. The venous blood from the interventricular septum was conveyed to the middle cardiac vein and great cardiac veins.
