“…According to Ahasan et al (2012) in rabbit, the renal arteries descend from the abdominal aorta. Although the origin of both renal arteries from the abdominal aorta varied, right renal artery descended cranial to the left renal arteries in 27 (96.43%) cases.…”

SUMMARY: Rabbits have been used as urologic models in many studies. The aim of this study was to characterize the renal morphology and anatomical variations of the renal pedicle in rabbit. The research ethics committee of Rio de Janeiro Federal Rural University approved this study. The animals were obtained from the university's necropsy unit. Dissections were performed in 50 adult rabbits, male and females, without macroscopic renal pathology. Kidney measurements were made with a digital caliper: length, width, and thickness. The length and origin of the renal arteries and main branches and length of the renal veins were also determined. The terminology of Nomina Anatomica Veterinaria was followed. The mean and standard deviation of the length of the right kidney was 3.150±0.2588 cm in males and 3.127±0.3769 cm in females and in the left kidney was 3.083±0.0818 cm in males and 3.162±0.0848 cm in females. The width of the right kidney was 1.933±0.0848 cm in males and 1.996±0.0680 cm in females and in the left kidney was 1.850±0.0659 cm in males and 2.004±0.0940 cm in females. There was no significant difference in the measurements between the two sexes and antimeres and in the measures of renal vessels in relation to sex, but the left artery and renal vein were always larger than the right in both sexes. The results of the present study are expected to contribute to the body of knowledge in the field of comparative and applied anatomy.

“…In addition, all the rabbits were male, raising the possibility that we failed to detect a difference in hepatic arterial size based on the sex of the animal. While there was no difference in the diameter of the celiac axis, a recent study did describe a significant difference in the arterial diameters of the left cranial abdominal artery and the caudal mesenteric artery of male versus female New Zealand white rabbits (16). This study also does not include an experimental component to evaluate whether subselective catheterization of the RHA would be as difficult as we surmise.…”

Background The VX2 rabbit model of liver cancer is commonly used to evaluate the efficacy of locoregional anticancer therapy and knowledge of the hepatic arterial anatomy in the rabbit is important for catheter-directed experiments. Purpose To describe the normal anatomy and anatomic variations of the celiac axis and hepatic artery in the rabbit. Material and Methods Angiograms of 222 rabbits were retrospectively reviewed. The branching pattern of the celiac axis was classified and the diameters of the major branches were measured. Paired t-tests were used to compare the difference between the average sizes of arteries. Results Variant celiac axis or hepatic artery anatomy was noted in 25.9% of angiograms, with the gastric branches arising from the proper hepatic artery in 23.3% of cases. The celiac axis could be successfully classified into one of five distinct branching patterns in 193 (86.9%) cases. The mean diameters of the right and left hepatic arteries were 0.67 mm (95% CI [0.64, 0.7]) and 1.25 mm (95% CI [1.19, 1.31]), respectively. The mean diameters of the medial and lateral branches of the left hepatic artery were 0.63 mm (95% CI [0.6, 0.67]) and 0.91 mm (95% CI [0.86, 0.96]), respectively. The right hepatic artery was significantly smaller than the left hepatic artery and the lateral branch of the left hepatic artery (all p-values <0.0001). Conclusion Arterial variants in the rabbit are not uncommon. The proper hepatic artery often gives origin to gastric artery branches. To facilitate superselective intra-arterial intervention, the left lateral lobe of the liver should be targeted for tumor implantation because of the significant size difference between the right and left hepatic arteries.

“…Severe vascular abnormalities were found in our affected rabbits ( Figure 13, 14 and 15) as compared to their healthy littermates (Figure 16 and 17), and the physiological arterial arrangement in the pelvic cavity and proximal part of the pelvic limbs (Ahasan et al 2013). To our knowledge, this is the first reported case of fast-flow vascular malformations in rabbits affected with PHA.…”

ABSTRACT:In this case report, three different crossbreedings of pet rabbits were performed producing affected as well as healthy bunnies. All affected rabbits were smaller and had local alopecia, exophthalmus, and limb deviations compared to their healthy littermates; thus, a homozygous form of Pelger-Huet anomaly was suspected. This anomaly was confirmed by blood examination in which granulocytes with oval nuclei and a very coarse chromatin pattern, as well as lymphocytes with micronuclei were noticed. Karyotype analyses of the lymphocytes revealed many chromosomal aberrations in affected rabbits. Moreover, severe arterial abnormalities in the pelvic cavity and proximal part of the pelvic limbs were also found in these rabbits. Our findings suggest a multigenic origin of Pelger-Huet anomaly in rabbits, because only male and female offspring with the otter colour of fur were severely affected by this congenital disorder.
