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

Öz

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.
