Özet
Bu araştırma, Yeni Zelanda Tavşanlarında bir lenf rezervuarı olarak bilinen cisterna chyli'nin oluşumu ve buradan başlangıç alan ductus thoracicus'un seyrini incelemek amacıyla yapılmıştır. Yapılan bu çalışmada, 8 adet ergin Yeni Zelanda Tavşanı kullanıldı. Materyaller, rompun-ketalar kombinasyonu ile anestezi edildikten sonra karın boşluğu açıldı. Daha sonra lnn. iliaci mediales, lnn. iliaci laterales, lnn. hepatici, lnn. gastrici, lnn. mesenterici craniales ve lnn. mesenterici caudales'e çini mürekkebi enjekte edildi. Bu işlemi takiben hayvanlar usulüne uygun olarak öldürüldü. Daha sonra materyaller diseke edilerek cisterna chyli ve ductus thoracicus'un oluşumu ve seyri ortaya çıkarıldı. Cisterna chyli'nin, 2.-3. lumbal omur düzeyinde lokalize olan ve oval mekik görünümlü düzensiz bir kesecik şeklinde olduğu gözlendi. Bir materyalde 4. lumbal omur düzeyine kadar ulaştığı tespit edildi. Cisterna chyli'ye caudal'den 2 dal halinde gelen trunci lumbales ile ventralden gelen tuncus visceralis'in açıldığı belirlendi. Ductus thoracicus'un, a. mesenterica cranialis'in orijini düzeyinde cisterna chyli'nin cranial ucundan orijin aldıktan sonra aorta ile birlikte göğüs boşluğuna geçtiği ve 7. thoracal omur düzeyine kadar aorta'nın sağında ve dorsal'inde seyrettiği gözlendi. Kalbin basis'ine kadar aorta'nın dorsal'inde seyrettikten sonra median hattın soluna geçtiği görüldü. Bir materyalde ductus thoracicus'un diaphragma'yı geçtikten sonra ikiye ayrıldığı tespit edildi. Ductus thoracicus'un, precardial bölgede sol m. longus colli üzerinden craniale doğru seyrettikten sonra bir genişleme yaptığı ve 6 materyalde v. cava cranialis sinister'e, 2 materyalde ise apertura thoracis cranialis'den cavum thoracis'i terkettikten sonra v. jugularis externa sinister'e açılarak sonlandığı tespit edildi.
In this study, both the formation of the cisterna chyli and courses of the thoracic duct were macroscopically investigated in New Zealand rabbits. In this purpose, eight of adult New Zealand rabbits were used. Animals were anaesthetized by the combinating of Rompun and Ketalar. Then, abdominal cavity was opened with a incision. Indian ink were injected into the lateral iliac lymphonode, medial iliac lymphonode, hepatic lymphonode, gastric lymphonode, cranial mesenteric lymphonode and caudal mesenteric lymphonode. After that, the courses and formations of the thoracic duct and cisterna chyli were studied by dissecting of the animals. Cisterna chyli is an elliptical sac like structure which lies at the level of the second and third lumbar vertebrae. In only one material, it was determined that the cisterna chyli extends from the second lumbar to fourth lumbar vertebrae. It was observed that the cisterna chyli received caudally two branches named lumbar trunk and ventrally visceral trunk.The thoracic duct arises from the cisterna chyli at the level of the origin of cranial mesenteric artery. Then it passed through the aortic hiatus of the diaphragm concominantly with aorta within the thoracic cavity, it situated to right and dorsal to the thoracic aorta from the diaphragm to seventh thoracic vertebrae. It was seen that the thoracic duct extends to the basis cordis and passes to the left side of the midline. In only one material, after passing to the diaphragm, it was observed that the thoracic duct divides into two branches. The precardial segment of the thoracic duct coursed to cranial at the left long colli muscle and dilates into an ampulla. It was determined that the thoracic duct ends in the left vena cava in six animals. But in two animals, it terminates into the left external jugular vein, after leaving the cranial thoracic aperture.
