Konya Merinosunda Aa. Renales’in Intrarenal Segmentasyonu

Konya merinosu koyun ırkı böbreklerinin arter dağılımı, diseksiyon ve korozyon kast teknikleri kullanılarak araştırıldı. Çalışmada 8 adet böbrek kullanıldı. Böbreklerin aorta abdominalis’den tek bir dal olarak ayrılan a. renalis’ler tarafından vaskularize edildiği gözlendi. A. renalis dextra’nın a. renalis sinistra’dan daha cranial’den orijin aldığı belirlendi. A. renalis sinistra’nın, a. renalis dextra’dan daha uzun ve daha kalın bir yapıda olduğu görüldü. Böbrek arteri hilus renalis’e girdikten sonra iki ana dala (dorsal ve ventral) ayrılmaktaydı. Ancak, materyallerin yarısında sol arterden üçüncü bir dal çıkmaktaydı. Bu dalların her iki böbrekte 2-5 adet a. interlobares’e ayrıldığı saptandı. Dorsal ve ventral dallar ile segmentleri arasında anastomoz görülmedi.

Intrarenal Segmentation of the Renal Arteries in the Konya Merino

Arterial distribution of Konya merino’s kidneys were investigated using dissection and corrosion cast techniques. Eight kidneys were used in the study. It was observed that the kidneys were vascularized by a. renalis, which separated as a single branch from aorta abdominalis. The origin of the a. renalis dextra was determined in cranial from the a. renalis sinistra. A. renalis sinistra was found longer and thicker structure than a. renalis sinistra. The renal artery was divided into two main branch (dorsal and ventral) after entering the hilum renis. However, half of the material had a third branch of the left artery. These branches, in both kidney was separated 2-4 pieces aa. interlobares. Dorsal and ventral branches did not show anastomosis between segments.
