Arterial Vascularization of Kidneys in the Hasmer Sheep

Abstract

The study was conducted to investigate the variations of renal arteries in Hasmer sheep. Six animals were used in the study. Renal artery and its segments were prepared using standard corrosion cast techniques and examined. An electronic calibrator was used to measure the length and diameter of the renal arteries. Renal arteries were originating from the abdominal artery, right and left. The left renal artery was longer than the right. Renal arteries were also divided into dorsal and ventral branches. Dorsal and ventral branches respectively; interlobar, arcuate and interlobuler arteries were separated. An interlobar artery originating from the ventral branch of both kidneys fed both the dorsal and ventral surfaces of the kidney. None of the materials had anastomosis.

Öz

Çalışma, Hasmer koyunlarında renal arterlerin varyasyonlarını araştırmak amacıyla yapıldı. Araştırmada altı adet hayvan

kullanıldı. Renal arter ve segmentleri standart korozyon kast teknikleri kullanılarak hazırlandı ve incelendi. Renal arterlerin

uzunluk ve çap ölçümleri için elektronik kalibratör kullanıldı. Arteria renalis’lerin, aorta abdominalis’ten sağlı ve sollu olarak

orijin aldıktan sonra dorsal ve ventral iki dala ayrıldığı tespit edildi. Sol renal arterin, sağ renal arterden daha uzun olduğu

belirlendi. Renal arterler dorsal ve ventral iki dala ayrılmaktaydı. Dorsal ve ventral dallar sırasıyla; interlobar, arcuate ve

interlobuler arterlere ayrıldığı gözlendi. Ayrıca, her iki böbreğin ventral kolundan orijin alan bir interlobar arterin, böbreğin

hem dorsal hem de ventral yüzünü beslediği belirlendi. Materyallerin hiçbirinde anastomoz görülmedi. Sonuç olarak; Bu tür

çalışmalar böbrek transplantasyonları, böbreklerin cerrahi operasyonları ve üriner hastalıklar gibi araştırmalara ışık tutabilir.
