The Anatomy of the cardiac veins in storks (Ciconia ciconia)

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 coronariusun bulunmadığı belirlendi. V. cardiaca sinistra ve v. cardiaca medianın v. cava cranialis sinistra ya açıldığı görüldü. V. cardiaca sinistranın 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 sinistranın bir çok damar aracılığı ile ventriculus sinister ve atrium sinistrumun venöz kanını topladığı görüldü. Ventriculus sinisterden çıkan v. cardiaca circumflexa sinistranın bir dalının diğer dallardan güçlü olduğu ve ventriculus sinisterin büyük bir bölümünü diranajını sağladığı tespit edildi. V. cardiaca medianın tek olarak şekillendiği belirlendi. Vv. cardiacae dextraenın doğrudan atrium dextruma açıldığı belirlendi. V. cardiacae minimaenın atrium dextrum duvarı ve septum interventricularenin venöz kanını topladıkları ve kalbin sağ boşluklarına açıldığı görüldü. Septum interventricularenin drenajını v. cardiaca media ile pars interventricularisin vv. septalesinin yaptığı tespit edildi. Sonuç olarak leyleğin koroner ven dolaşımı tavuk ve devekuşundan ziyade kemirgenlere daha çok benzediği görüldü.

Leyleklerde (Ciconia ciconia) kalp venlerinin Anatomisi

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.
