Yeni Zelanda Tavşanında Arteria Celiaca’nın Seyri ve Dağılımı Üzerinde Makroanatomik Araştırmalar

Bu çalışmada Yeni Zelanda tavşanında arteria celiaca’nın seyri ve dağılımı makroanatomik olarak incelendi. Çalışmada 8 adet Yeni Zelanda tavşanı (Oryctolagus cuniculus : Rodentia) (4 erkek, 4 dişi) kullanıldı. Materyallere aorta abdominalis aracılığı ile kırmızı boya ile renklendirilmiş latex ve mono-polymethymethacrylate (takilon) enjekte edildi. Arteria celiaca’nın aorta abdominalis’in ventral yüzünden başlangıç aldığı ve arteria lienalis, arteria gastrica sinistra ve arteria hepatica’yı vererek sonlandığı belirlendi. Arteria lienalis’in arteria celiaca’ nın sol kenarından orijin aldığı ve arteria gastroepiploica sinistra adı altında sonlandığı gözlendi. Arteria gastrica sinistra’nın arteria gastrica dextra ve arteriae gastricae breves ile anastomozlaştığı ortaya konuldu. Yeni Zelanda tavşanlarında arteriae gastrica breves’lerin arteria lienalis’den köken aldığı gösterildi. Çalışmada ayrıca arteria hepatica propria’nın arteria hepatica’nın bir dalı olmadığı tesbit edildi. Arteria hepatica’nın arteria gastrica sinistra ayrıldıktan sonra arteria celiaca’nın devamı durumunda olduğu ve arteria gastroduodenalis, pylorus ve omentum minus’a yan dallar ile arteria gastrica dextra ve arteria gastrica sinistra’nın ortak kökünü verdikten sonra sağ ve sol dallara ayrılarak sonlandığı belirlendi. Arteria celiaca’nın dalları ve dağılımının cinsiyete bağlı olmadığı tesbit edildi.

Macroanatomic Investigations of the Course and Distribution of the Celiac Artery in the New Zealand Rabbit

The course and distrubution of the celiac artery was investigated macroanatomically in the New Zealand rabbits in this study. A number of eight New Zealand rabbits (Oryctolagus cuniculus: Rodentia) (four male, four female) were used in the study. The materials were injected with red colored latex and corrosion casted with mono- polymethymethacrylate (takilon) through the abdominal aorta. It was determined that the celiac artery arose from the ventral surface of the abdominal aorta, and terminated giving off the lienal, left gastric and hepatic arteries. It was observed that the lienal artery originated from the left border of the celiac artery and terminated under the name of the left gastroepiploic artery. It was state that the left gastric artery anastomosed with the right gastric and short gastric arteries. It was indicated the short gastric arteries was determined to stem from the lineal artery in the New Zealand rabbits. In the study, it was also observed that the proper hepatic artery was not to be a branch of the hepatic artery. It was determined that the hepatic artery was the continuation of the celiac artery after leaving the left gastric artery and terminated splitting the right and left branches after giving off the common stem of the right and middle gastric arteries, the side branches to pylorus and lesser omentum and the gastroduodenal artery. The branches and distribution of the celiac artery were found to be not gender dependent.
