Arteria renal triple en un perro: una rara variación anatómica

Abstract

Renal arteries have been anatomically studied, particularly emphasizing numerical variation across different animal species. The origins of renal arteries from the abdominal aorta vary according to renal topography in many species. The right renal artery originates more cranially than the left due to the cranial position of the right kidney. This report describes a case of a left triple renal artery arising from the lateral surface of the abdominal aorta in a male mongrel adult dog. During dissection, it was observed that three renal arteries supplied the left kidney with different topographies and arrangements. The right kidney was supplied by a single renal artery. Numerical variations in canine renal arteries must be considered in surgical and experimental procedures to avoid errors arising from unfamiliarity with these variations.
