THE STRUCTURES AROUND EPIPLOIC FORAMEN , WHERE
THEY ORIGINATE AND WHERE THEY GO NEXT.
Epiploic Foramen Also Called As Epiploic Foramen Is A Passage Of Communication With Greater Sac And Lesser Sac of peritoneal cavity.
It has following boarders :
* Left lateral
The anterior boarder of omental foramen have the free boarder of lesser omentum. It is the part of peritoneum stretching between the lesser curvature of the stomach and the visceral surface of the liver. The lesser omentum is extremely thin, and is continuous with the two layers of peritoneum which cover respectively the antero-superior and ...view middle of the document...
1 : common bile duct –
The common bile duct (ductus choledochus) is a tube-like anatomic structure in the human gastrointestinal tract. It is formed by the union of the common hepatic duct and the cystic duct (from the gall bladder). It is later joined by the pancreatic duct to form the ampulla of Vater. And then opens into duodenum.
2: Hepatic artery-
The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus (a part of thestomach), duodenum (a part of the small intestine) and pancreas.
It arises from the celiac artery and has the following branches:
* Hepatic artery proper
* Gastroduodenal artery
* Right gastric artery
Right gastric artery (pyloric artery) arises above the pylorus from the proper hepatic artery or less frequently from the common hepatic artery, descends to the pyloric end of the stomach, and passes from right to left along its lesser curvature, supplying it with branches.
3.Hepatic portal vein-
The hepatic portal vein is formed behind the neck of the pancreas by the union of the superior mesenteric vein and splenic vein. After its origin, it ascends to the right behind the first part of duodenum to enter the lesser omentum. It then runs upward in front of the opening into the lesser omentum (epiploic foramen), and reaches the porta hepatis, where it divides into right and left terminal branches.
In the posterior boarder the peritoneum covers the inferior venacava. The inferior vena cava (or IVC), also known as the posterior vena cava, is the large vein that carries deoxygenated blood from the lower half of the body into the right atrium of the heart.
Inferior venacava and aorta is an example of retroperitoneal organs in the abdomen.
The inferior venacava is formed by the union of 2 common iliacvein and to right of aortic bifurication. Inferior venacava on right side of aorta and parallel to it until reach the level of lower pole of kidney where it diverge slight to right from abdominal aorta and travels in a groove on the posterior surface of liver.
Lower part of liver is covered by peritoneum up to level of mesenteric root . as it ascends , the inferior venacava looses its peritoneum covering and is apposed to duodenum and pancreas..
Ascending to the posterior wall of epiploic foramenthe venacava, is again covered with the peritoneum and is adhered to he base area of liver in the groove for inferior venacava.
The caudate lobe (posterior hepatic segment I, Spigelian lobe) is situated upon the postero-superior surface of the liver on theright lobe of the liver, opposite the tenth and eleventh thoracic vertebrae. It is bounded on the left side by the physiological division of the liver called the ligamentum venosum.
It is bounded, below, by the porta; on the right, by the fossa for the inferior vena cava; and, on the left, by the fossa for the ductus venosus.
It looks backward, being nearly vertical in...
