“…Whereas the left gastric artery finally entered the stomach wall at the lesser curvature in 79% of the rabbits, this artery continued as the hepatic artery without entering the stomach wall in 21% of the rabbits in the present study. The latter pattern has previously been seen in 6.7% of New Zealand rabbits [ 1 ], but not in other studies of rabbits [ 3 , 4 , 18 , 21 ] and rodents [ 2 , 4 , 6 , 7 , 8 , 12 , 14 , 17 , 19 , 22 , 23 , 24 ]. Thus, we think that this direct continuation of the left gastric artery to the hepatic artery may occur more frequently in the New Zealand White rabbit than in other breeds and/or in rabbits with different ages, and in rodent species studied previously.…”

“…This is consistent with previous reports in the rabbit [ 1 , 3 ]. Although the origin of the left gastric artery has been reported to differ in individual rabbits [ 4 ] and in rodent species that are phylogenetically close to lagomorphs, such as guinea pigs [ 4 , 19 ], North American beavers [ 6 ], muskrats [ 7 ], hamsters [ 8 ], rats [ 12 ], wood mice [ 14 ], degus [ 23 ] and Mediterranean pine voles [ 24 ], no such individual variation was seen in the present study. The difference between the previous rabbit study [ 4 ] and the present one may be due to the difference in rabbit breeds and/or ages, although the breed and age were not specified in the previous study [ 4 ].…”

Gastric stasis is common in rabbits, and gastrotomy may be performed to cure this pathological condition. Detailed descriptions of the arterial supply to the stomach are essential for this surgical operation, but published descriptions are limited. Here, we investigated anatomical variations of the arterial supply to the stomach in 43 New Zealand White rabbits by injecting colored latex into arteries. We observed that the left gastric artery that arose as the second branch from the celiac artery provided 1–3 parietal and 1–3 visceral branches to the stomach, with various branching patterns depending on the case. In 34 of 43 cases, the left gastric artery ended upon entering the gastric wall at the lesser curvature, whereas in the remaining cases, the artery continued as the hepatic artery without entering the gastric wall. The right gastric artery that branched off from the gastroduodenal artery also supplied the lesser curvature sinistrally but did not anastomose with the left gastric artery. In 40 cases, the hepatic artery provided 1–4 pyloric branches. In the fundic region, the short gastric arteries arose from the splenic artery and varied in number from 2 to 6. The right and left gastroepiploic arteries anastomosed to give 2–7 branches to the greater curvature. The results showed that many variations occurred in the arteries supplying the rabbit stomach, suggesting that such variations should be considered when performing veterinary surgical treatments in rabbits.

“…This one rabbit is considered to be an exceptionally rare case, because other previous reports in the rabbit [ 1 , 2 , 14 ] consistently showed that the splenic artery was the first branch of the celiac artery, in agreement with our present results. In rodents, there are individual and/or species variations; the splenic artery is usually the first independent branch of the celiac artery in the Mediterranean pine vole [ 20 ], muskrat [ 6 ], wood mouse [ 11 ] and degu [ 19 ], frequently not the first independent branch in the dormouse [ 18 ], and never in the North American beaver [ 5 ] and guinea pig [ 4 , 16 ].…”

“…In rodents, which are the closest relative to the lagomorph, the origin of the splenic artery varies in each species. For example, whereas in the rat [ 10 ], dormouse [ 18 ] and Mediterranean pine vole [ 20 ], the splenic artery usually arises as one of the trifurcated branches of the celiac artery, this artery usually arises as the first independent branch of the celiac artery in the hamster [ 7 ], muskrat [ 6 ], wood mouse [ 11 ] and degu [ 19 ] or as the second independent branch in the North American beaver [ 5 ]. Another pattern is seen in the guinea pig [ 4 , 16 ], where the splenic artery usually arises as a common trunk with the left gastric artery.…”

Anatomical variation of arterial supply to the rabbit spleen

ABSTRACT. The rabbit, which is widely used as an experimental animal and is also popular as a companion animal, has a flat and elongated spleen with the longitudinal hilus running along its visceral surface. The spleen receives via the hilus an arterial supply that is essential for splenic nutrition and normal functioning. However, the distribution and variation of the arteries to the spleen have not been studied in detail. This study investigated anatomical variations of splenic arterial supply in 33 New Zealand White rabbits with a colored latex injection into arteries. We also examined whether the length of the spleen correlated with the number of the splenic branches of the splenic artery. The splenic artery always arose as the first independent branch of the celiac artery and ran along the splenic hilus to usually provide 6 (range, 3 to 10) splenic branches to the spleen. There was a moderate correlation (R=0.6) between the number of splenic branches and the longitudinal length of the spleen. The splenic branches often arose as a trunk or trunks in common with short gastric arteries. The number of common trunk(s) was usually 1 (range, 0 to 4). The data showed that the pattern and number of arterial branches to the spleen varied according to the individual animal, suggesting that such variations should be considered when performing experimental and veterinary surgical treatments in rabbits.

Background Information on the anatomy of the abdominal arterial system in Insectivora is scarce. We described the origin, distribution, and variations of the visceral abdominal arteries in some Soricidae in order to provide the first comprehensive data on this subject in Insectivora. Results were interpreted from a functional and phylogenetic viewpoint. Methods The sample examined consisted of 46 shrews (25 Crocidura russula, 12 Sorex araneus, 5 S. coronatus, 4 S. minutus) captured in the field. Animals were analyzed by injection of coloured latex solution through the left ventricle of the heart and subsequent dissection. Results The coeliacomesenteric trunk was the first visceral branch of the abdominal aorta. The cranial mesenteric artery supplied those parts of the digestive tract attached to the cranial mesentery and usually gave rise to the colic, the caudal pancreaticoduodenal, and the jejunum‐ileum‐colic arteries. The coeliac artery mainly vascularized the stomach, the liver and the first portion of the duodenum, and the spleen by means of several branches of the left gastric, the “common” hepatic, and the lienal arteries, respectively. The lienal arteries were double. The renal, gonadal, and median sacral arteries were also branches of the abdominal aorta. The caudal mesenteric artery emerged either from the abdominal aorta or from one of the common iliac arteries. Conclusions Differences in the abdominal blood supply between soricids and more advanced mammals are basically focused on the irrigation of the digestive tract. The presence of double lienal arteries and the absence of right gastric artery and left and right gastroepiploic arteries are related to the primitive type of gut presented in the order and are thought to be the plesiomorphic condition in Eutheria.
