Part of Mammalia class, THERIA subclass, Eutheria group, Rodenția order, Hystricomorpha suborder, Chinchilidae family, Chinchilla species, this smalls rodents are very popular lately as pets.Our study attempts to describe the origin, traject and macroscopically visible distribution of the renal arteries in Chinchilla lanigera, and the obtained results were compared with data reported in other species.
Materials and methodsThe biological material originates from a private farm from Bistrița County (Romania) and is represented by five female chinchilla carcasses. After the intraabdominal approach, intra-arterial lavage with heparinised serum was performed and then injected a in the descending abdominal aorta (Aorta abdominalis) with 30 ml of acrylic/ latex coloring agent. After a 5 days fixation period in 5% formaldehyde solution, the carcasses were dissected and the observed aspects were photographed and described.
Results and discussionsAfter the stratigraphic dissection we observed that in chinchilla, the renal arterie's (A.renalis) origins are found on the left and right side of the abdominal aorta, caudally to the cranial mesenteric artery (A. mesenterica cranialis).In contrast with the chinchilla, the literature reports different aspects in rats (Moffat and Fourman, 1963;Yoldas et al., 2014) and Wistar mouse species (Nur and Yaldş, 2011), where the right renal artery arises from abdominal aorta, cranially to the origin of cranial mesenteric artery.In Chinchilla lanigera, the first renal branch is represented by the right renal artery (A.renalis dextra), while the left renal artery's origin (A.renalis sinistra) is situated at 0,5 centimeters caudally from the first branch. Similar aspects were reported in literature in rabbit (Maženský et
Origin, Traject and Distribution of Renal Arteries (Arteriae renalis) in Chinchilla lanigera
AbstractFor the present study a number of 5 female chinchilla carcasses were used. The animals were slaughtered for commercial purpuses (fur). The anatomical dissection started with the identification of the aorta (Aorta abdominalis). The next step was the intra-arterial injection of a colouring substance. The carcasses was fixed in the formaldehyde solution and subsequently the renal arteries were dissected. The first renal artery was the right renal artery (Arteria renalis dextra) and, at 0,5 cm caudally, the left renal artery (Arteria renalis sinister) arose . The origin of those arteries were disposed on the lateral part of the abdominal aorta.The origin, traject and distribution of renal arteries on the studied species have a high degree of similarity with the literature dates described for leporids.
