Özet
Bu çalışmada, leylekte koroner venlerin başlangıç, seyir ve dallanmaları incelendi. Bu amaçla dokuz adet yetişkin leyleğe renklendirilmiş latex verildi. Kalbin venöz drenajının v. cardiaca sinistra, v. cardiaca media, vv. cardiacae dextrae ve vv. cardiacae minimae tarafından sağlandığı tepit edildi. Sinus coronarius’un bulunmadığı belirlendi. V. cardiaca sinistra ve v. cardiaca media’nın v. cava cranialis sinistra’ ya açıldığı görüldü. V. cardiaca sinistra’nın kalbin venöz kanını toplayan en güçlü ven olduğu tespit edildi. Bu damarın, pars interventricularis ve v. cardiaca circumflexa sinistra olarak iki bölümden oluştuğu görüldü. V. cardiaca circumflexa sinistra’nın bir çok damar aracılığı ile ventriculus sinister ve atrium sinistrum’un venöz kanını topladığı görüldü. Ventriculus sinister’den çıkan v. cardiaca circumflexa sinistra’nın bir dalının diğer dallardan güçlü olduğu ve ventriculus sinister’in büyük bir bölümünü diranajını sağladığı tespit edildi. V. cardiaca media’nın tek olarak şekillendiği belirlendi. Vv. cardiacae dextrae’nın doğrudan atrium dextrum’a açıldığı belirlendi. V. cardiacae minimae’nın atrium dextrum duvarı ve septum interventriculare’nin venöz kanını topladıkları ve kalbin sağ boşluklarına açıldığı görüldü. Septum interventriculare’nin drenajını v. cardiaca media ile pars interventricularis’in vv. septales’inin yaptığı tespit edildi. Sonuç olarak leyleğin koroner ven dolaşımı tavuk ve devekuşundan ziyade kemirgenlere daha çok benzediği görüldü.
This study was carried out to describe the origin, course and ramifications of the cardiac veins in storks. For this purpose, coloured latex injection method was applied on heart of nine adult storks. The results indicate that venous drainage of the heart was provided by the v. cardiaca sinistra, the v. cardiaca media, the vv. cardiacae dextrae and the vv. cardiacae minimae. The coronary sinus was not found in all samples. The v. cardiaca sinistra and v. cardiaca media were opened into the v. cava cranialis sinistra. The v. cardiaca sinistra was the largest vein providing to venous drainage of heart which consisted of two main parts pars interventricularis and v. cardiaca circumflexa sinistra. The v. cardiaca circumflexa sinistra was collected to venous blood of the ventriculus sinister and atrium sinistrum by means of several vessels. One branch of the v. cardiaca circumflexa sinistra coming from ventriculus sinister was much larger than rest and drained big part of ventriculus sinister. The v. cardiac media was a single vein. The vv. cardiacae dextrae were opened directly into the right atrium. The vv. cardiacae minimae were collected venous blood from the wall of atrium dextrum and interventricular septum and emptied into the right chambers of heart. The venous blood of the interventricular septum was collected by the vv. septales of pars interventricularis and v. cardiaca media. It was concluded that circulation of cardiac veins in stork closely resembles that of rodent and is unlike both fowl and ostrich patterns.
