Macroanatomic Investigations on the cisterna Chyli and Thoracic Duct of the White New Zealand Rabbit

Öz

In this study, both the formatioo of the cisterna chyli and courses of the thoracic duct were macroscopically
investigated in New Zealand rabbits. In this purpose, eight of aduh New Zealand fabbhs were used. Ani'
mals 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 Iymphonode, medial iliac Iymphonode, hepatiC Iymphonode, gastric
Iymphonode, cranial mesenteric Iymphonode and caudal mes&rlleric Iymphonode. After that, the courses and formations
of the thoracic duet and cisterna chyli wera 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, 11 was detennined
that the cistema chyli extends from the secood lumbar to fourth lumbar vertebrae. It was obseNed that the
cisterna chyli recerved caudally IWO branches named lumbar trunk and ventrally visceral trunk,The thoracic duct anses
Irom the cisterna chyll altha level of the ongin 01 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 lhoracic vertebrae. It was seen Ihatthe thoracic: duct extends to the basis cordis
and passes to the left side of Ihe midline. In only one material, after passing to the dlaphragm. it was obseNed that
the thoracic ducl divides Into two branches. The precardial segment of the thoracic duct coursed to cranial at the left
long colli muscle and dilales into an ampulla. It was determined thai the thoracIC duel ends In the left vena cava In SIX
animals. But in two animals, it tellT'llnates Into the left external jugular vem, after leaving lhe craOal thoracIC aperture.
