Özet
Bu çalışmada, Kıvırcık koyununda koroner arterlerin makroanatomik özelliklerini ortaya koymak amaçlandı. Araştır mada 14 adet Kıvırcık koyunu kalbi kullanıldı. Koroner damarlara renklendirilmiş latex enjekte edildi. Diseke edilen kalpler incelenerek fotoğraflandı. Kıvırcık koyunlarında kalbin arteriyel vaskularizasyonunun, a. coronaria dextra ve a. coronaria sinistra tarafından sağlandığı gözlendi. A. coronaria dextra ve dallarının daha zayıf ve az sayıda septal dal verdiği belirlendi. A. coronaria dextra’nın iki koyunda orijininden sonra iki dala ayrıldığı saptandı. A. coronaria dextra’nın, sulcus coronarius’a yönelen dalının atrial dalları, distal’e yönelen dalının ise ventrikular dalları verdiği tespit edildi. R. distalis atrii dextri’nin üç kalpte bulunmadığı saptandı. R. marginis ventricularis dextri ile r. distalis ventriculi dextri’nin altı kalpte ortak bir kök ile çıktıkları belirlendi. A. coronaria sinistra’nın beş numunede r. interventricularis paraconalis ve r. circumflexus sinister’e ayrıldığı; bu iki dala ilave olarak, dokuz numunede, r. proximalis atrii sinistri, üç materyalde r. septalis, bir numunede ise r. intermedius atrii sinistri’nin a. coronaria dextra’dan ayrıldığı belirlendi.
The aim of this study was to determine the macroanatomical properties of coronary arteries of Kıvırcık sheep. In this study, 14 Kıvırcık sheep hearts were used as the material. The coronary arteries were filled by the injection of coloured latex. Dissected hearts were evaluated and photographed. Arterial vascularisation of the heart was provided by the left and right coronary arteries. The septal branches from which the right coronary artery and its branches gave off during their course were lesser in number and thinner than the septal branches from which the left coronary artery and its branches gave off during their course. The right coronary artery divided into two branches after its origin in two samples. The branch directed to coronary groove gave off the atrial branches, while the other branch directed distally gave off the ventricular branches. The right distal atrial branches were not observed in three hearts. The right ventricular marginal and distal branches were originated from a common root in six materials. The left coronary artery divided into the paraconal interventricular and left circumflex branches in five of 14 samples. In addition to these two vessels, it gave off the left proximal atrial branch in nine samples, septal branch in three samples and left intermediate atrial branch in one heart.
