AKKARAMAN KOYUNUNDA KORONER VENLERİN ANATOMİSİ

Abstract

Bu çalışma koyunların kalplerindeki koroner venlerin anatomisini araştırmak ve bu konuda yapılan çalışmalara katkıda bulunmak amacıyla yapıldı. Araştırmamızda 3-6 yaşlarında, 50-60 kg canlı ağırlığında, 17 adet dişi, Akkaraman ırkı koyun kalbi kullanıldı. Kalplerin koroner venlerinin anatomisi plastik enjeksiyon ve korozyon yöntemiyle incelendi. Kalplerin tamamında vena (v.) azygos’un sinus coronarius’a açıldığı belirlendi. Kalplerin birinde (1/17) v. cordis magna ile v. cordis media’nın sinus coronarius’a giriş yerlerinin arasında literatürlerde belirtilmeyen bir venin, başka bir kalpte (1/17) iki venin sinus coronarius’a açıldığı tespit edildi. Kalplerin tamamında v. cordis magna’nın sinus coronarius’a açıldığı, çoğunda ise (15/17) v. cordis magna’nın dallarında varyasyonlar olduğu tespit edildi. Kalplerin 13/17’sinde v. marginalis ventricularis sinistri’nin, v. cordis magna’ya, 4/17’sinde ise sinus coronarius’a açıldığı belirlendi. Kalplerin iki tanesinde (2/17) v. marginalis ventricularis sinistri’nin yanında 2. bir ven olduğu, bunların v. cordis magna’ya açıldığı tespit edildi. Kalplerin çoğunda (11/17) v. cordis dextra’nın kalbin sağ kenarını dolanarak, bazılarında (6/17) ise kalbin sağ kenarında sağ atrium’a açıldığı tespit edildi. Kalplerin 3/17’sinde v. distalis ventriculi dextrii’nin, v. cordis dextra’ya, 2/17’sinde sağ atrium’a açıldığı görüldü. Diğer kalplerde bu durum gözlemlenmedi. Kalplerin tamamında v. cordis media’nın sinus coronarius’a açıldığı, bu venin dallarının varyasyon gösterdiği tespit edildi. Kalbin venlerinin aralarında çok sayıda anastomoz bulunduğu belirlendi

Anatomy of the Coronary Veins in Akkaraman Sheep

Abstract

The aim of this study is to search coroner vein anatomy in the hearts of the Akkaraman sheep. In our study between 3-6 aged, 50-60 living weighed, in a number of 17 female Akkaraman sheep’s hearts were used. Anatomy of hearts coroner veins were examined with plastic enjection and corrosion cast method. In all hearts, azygos vein was opened to coronary sinus. It was determined that in one of the hearts (1/17) between enterance areas of great cardiac vein and middle cardiac vein to coronary sinus there was a vein that was not specified in literature and in an other heart (1/17) it was determined that two veins were opened to coronary sinus. It was determined that in all hearts great cardiac vein was opened to coronary sinus and in most of the hearts there were variations in the branches of great cardiac vein. It was found that in 13/17 hearts, left marginal vein was opened to great cardiac vein and in 4/17 it was opened to coronary sinus. In two of the hearts (2/17) there were second vein beside left marginal vein, these two veins were opened to great cardiac vein. It was found that in most of the hearts(11/17) right coronary vein was opened with coiling the heart’s right edge and in some of the hearts it was opened (6/17) to right atrium in the right edge of the heart. It is found that in 3/17 of the cases v.distalis ventriculi dextrii was opened to right coronary vein and in 2/17 of them it was opened to right atrium. We could not observe this situation in other hearts. It was determined that in all hearts middle cardiac vein was opened to coronary sinus and the branches of this vein showed variations. Among the heart veins there was considerable anastomosis.
