Hasmer Koyununda Böbreklerin Arteriyal Vaskularizasyonu

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.

Arterial Vascularization of Kidneys in the Hasmer Sheep

The study was conducted to investigate the variations of renal arteries in Hasmer sheep. Six animals were used inthe study. Renal artery and its segments were prepared using standard corrosion cast techniques and examined. An electroniccalibrator was used to measure the length and diameter of the renal arteries. Renal arteries were originating from theabdominal artery, right and left. The left renal artery was longer than the right. Renal arteries were also divided into dorsaland 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. As a result; Such studies may shed light on research such as renal transplantations,surgical operations of the kidneys and urinary diseases.
