Abstract

In this study, formation of the cisterna chyli and course and termination of the thoracic duct were mac-roscopically investigated. In this purpose, eight Akkaraman sheep were used. India ink were injected to various nodes of these animals. The thoracic duct originated from the cranial part of the cisterna chyli and coursed dorsolaterally of the thoracic aorta at the right of the median plane. At the fourth and fifth lumbar vertebra it inclines somewhat cranioventrally and passes to left side of the median plane. It was determined that the thoracic duct terminated to the dorsolateral surface of the left external jugular vein at the level of the first rib. In this research, it was observed that the cisterna chyli is located saclike, an elongated lymph reservoir at the ventral to large psoas muscle at the level of the second and third lumbar vertebra. Two small lymphatics joined together and formed lumbal trunks which opens to cisterna chyli, following a short courses. At the level of the third lumbar vertebra, the cisterna chyli receives the lumbar, visceral and coliac. Viscera! trunke is formed by the jejenal, intestinal and colic trunks. The celiac trunks is formed by the hepatic and gastric trunks.

Özet

Bu araştırmada cisterna chyli'nin anatomik oluşumu ve buraya katılan efferent damarlar ile ductus thoracicus'un seyri, aldığı efferent damarlar ve açıldığı venaiar incelendi. Bu amaçla 8 adet Akkaraman koyunu kullanıldı ve çeşitli lenf yumrularına siyah çini mürekkebi enjekte edildi. Ductus thoracicus'un cisterna'nın cranial ucundan çıkarak postcardial bölgenin sağında ve aorta thoracica'nın dorsolateralinde seyrettiği ve 4-5. thoracal vertebra düzeyinde sol tarafa geçerek cranioventrai yönde ilerlediği beirlendi. Bu lenf damarının 1. costa düzeyinde v. jugularis externa si-nistra'nın dorsolateral yüzüne açılarak sonlandığı belirlendi. Bu çalışmada lenf rezervuarı olan cisterna chyli'nin 2.-3. lumbal vertebra düzeyinde ve m. psoas major'un ventralinde oval bir kesecik şeklinde olduğu tespit edildi. 3. lumbal vertebra düzeyinde, trunci lumbales, truncus visceralis ve truncus celiacus'un bağımsız olarak aynı düzeyde cisterna chyli'ye açıldıkları belirlendi. Trunci lumbales'in 2 ince dal halinde birleşerek, cisterna chyli'ye açıldığı tespit edildi. Truncus visceralis'in truncus intestinalis, truncus colicus ve truncus jejunalis'in birleşmesiyle oluştuğu gözlendi. Truncus celiacus'un ise, truncus hepaticus ve truncus gastricus'un birleşmesiyle oluştuğu belirlendi.
