“…The left branch consists of a transverse and an umbilical part. The transverse part has several branches for the papillary process and the quadrate lobe, while the umbilical part gives off three branches that ramify in the left and quadrate lobes (18). The portal vein is connected through the hepatic capillary system and the hepatic veins to the caudal vena cava (15) but no interconnecting branches was found between these vessels at our macroanatomic vascular study.…”

The study aimed to evaluate the comparative anatomy of the liver and intrahepatic branching of the portal vein of the Eurasian otter (Lutra lutra) and the American mink (Neovison vison). Due to their highly valuable fur, minks have expanded their range to many parts of Europe and become available for many biomedical studies. In this study, ten adult minks and five otters were used. The 2 intrahepatic branching of the portal vein was studied by the combined injection and dissection technique. The macroscopic anatomy of the liver revealed that both species have six-lobed livers, although differences in shape, size and some additional fissures were documented. The portal vein, upon entering the liver, divides into the right and left branches. The branching pattern in otters had an additional branch at this level with a caudate process branch. The right branch of the portal vein ramified in the right lateral lobe and the caudate process in the mink livers, while the right branch in the otter livers only distributed functional blood to the right lateral lobe. The larger left portal branch, with its transverse and umbilical parts, ramified in the left liver portion, along with the quadrate, right medial lobe and papillary process.

“…Basic insights into the otter liver revealed that the otter has six or seven hepatic lobes (1,13). The intrahepatic branching of the portal vein was described in dogs (3,10,24) and cats (8), but also in other domestic animals such as sheep (7), rabbits (8), horse (23), buffalo (18), camels (22), as well as in humans (5).…”

“…The left branch runs at first in the long axis of liver from the porta toward the left lob then lies very close to visceral surface between the caudate and quadrate lobes, that covered by the papillary process, fat and hepatic lymph nodes [5,6]. Ranjbar, R., and L.A. Ghadiri (2011) reported that Iranian buffalo hepatic vein divided into two branches as left and right [8]. Ellenport reported that caudal vena cava receives two or three large hepatic veins in dogs [3].…”

The liver is the largest gland in the digestive system. Most parts of the liver are placing in the right region of the abdominal cavity and fixed by special ligaments, arteries and veins. The blood of the digestive system is drained into the liver by the portal vein. In this survey, the relationship between portal vein with hepatic veins, types of hepatic veins, manner of drainage of hepatic veins and also manner of drainage of the portal vein into caudal vena cava are studied.Thirty healthy livers of buffalo are selected from Urmia industrial slaughterhouse and biometrical studies performed on them. Also, the latex injection is used for observation of anastomosis of different veins in the liver.Results of liver biometry are followed:Average of weight of liver = 4380±1173/30gr, average of length of liver = 467.5±47/00972mm, average of wide of liver = 270.8±38/90934 mm270.8±38/90934 mm, average length of gallbladder = 109.66±13/7673mm, average of wide of gallbladder = 70.4±17/7426mm, average of caudal vena cava canal = 151.06 ±28.6854, Average of diameter of portal vein = 30.93±4.4430 and average of caliber of portal vein in entrance to liver = 39.26±6.2098.The liver veins were short veins, which are occupied parenchyma of the liver. These veins are received more branch of small veins. All of these veins were draining into abdominolateral wall of inter hepatic part of the portal vein. Results of this research are showed which inter hepatic veins have a different diameter. Rang of this diameter was from 0.5 to 3 mm or more. Interhepatic veins were classified according to the size of their calibre into three groups, large intrahepatic veins (they were generally more 3mm in diameter), intermediate interhepatic veins (they were 1to 3 mm in diameter) and small interhepatic veins (they were less 0.5 to 1 mm in diameter). Results of this study are showed which the average number of large foramen were 3.8, the average number of medium foramen was 8.3, and an average number of small foramen was 36.56. The studies on derivatives of portal vein on the buffalo liver have appeared which portal veins are dividing three principals trunks (left, middle and right). Left principle trunk is dividing into three branches (proximal, middle and distal). The outlet of all three types of hepatic veins had a valvular fold in entrance into caudal vena cava, which is named operculum the direction of this valve was toward the heart. Also, these research results have appeared which liver of buffalo is weightier and bigger than cattle.

“…The parenchymal distribution of the both the portal and hepatic veins in domestic animals have been studied in camel (3), in buffalo (4), in pig (5), in goats (6) and in sheep (7). The outcome of this investigation may served as guide for successful study to be able distinguish the portal and hepatic veins in the liver at autopsy and know the tributaries to the portal and hepatic vein and its branches in the liver to be able to diagnose a portosystemic shunt on venography and locate it at surgery (8 and 9) , and multiple collateral shunting vessels of the parenchyma dilated vessels in the hepatic parenchyma in arteriovenous fistula in the liver may be presented for evaluation of gastrointestinal foreign bodies (10).…”

The main purpose of this study was to convey a more precise explanation of the intrahepatic pattern of the tributaries of portal and hepatic veins in sheep and goats. Also to give broad information on the portal and hepatic vein and there topographic relation that may give a useful base for the hepatic segmentation, aiming to provide a correct base for surgical procedures and liver transplantation. Twelve livers collected from adult sheep and goats of both sexes. The portal and hepatic veins were studied by using cross dissection, corrosion cast and radiographic examination.Subject of this investigation show the portal vein of the sheep is slightly narrower than that of the goat. Also the pattern of intrahepatic branches of portal vein in sheep is similar to that of goat. on reaching the portal hepatic, gave of a right dorsal interlobular branch and then terminate into a right ventral interlobular and left interlobular branches , the right dorsal interlobular branch was short and large, supplied the caudate process and right dorsal hepatic lobe .The right ventral interlobular branch is distributed only in the ventral part of the right lobe, while the left branch was long and narrow, supplied the left and quadrate lobes as well as the papillary process, However the caudate process receives the separate branch from the parotid vein in goat. Moreover, the study revealed that the hepatic veins in sheep and goats can be classified into two groups ; large and small , the work also shows that there are (3-4) large hepatic veins in sheep, while in goats usually gives off a left large branch and two smaller right and intermediate branches, and in both animals the hepatic vein, pour in the caudal vena cava independently, the veins of the left, right and intermediate lobes empty themselves close to each other, while of these of the caudate and papillary processes open separately and a way from hepatic veins
