Where are the gastric arteries located?
the stomachThe right and left gastric arteries are situated along the lesser curvature and the right and left gastroepiploic arteries situated along the greater curvature of the stomach. A few branches from the splenic artery (short gastric arteries) supply the fundus.
How many short gastric arteries are there?
The gastroepiploic artery (GEA) is made up of two arteries which supply the greater omentum and the stomach. The right gastroepiploic artery (RGEA) is also referred to as the right gastro-omental artery or arteria gastroepiploic dextra in older texts.14 Oct 2021
Where does the left gastric artery come from?
The left gastric artery arises from the superior surface of the splenic artery distal to the division of the celiac trunk into the main hepatic and splenic arteries. The left gastric artery is distributed predominantly to the left lobe of the liver with lesser gastric supply.
Which ligament contains the short gastric arteries?
The gastrosplenic ligamentStructure. The gastrosplenic ligament is made of visceral peritoneum. It connects the greater curvature of stomach with the hilum of the spleen. It contains the short gastric arteries, short gastric veins, the left gastroepiploic artery, and the left gastroepiploic vein.
What do short gastric arteries supply?
The splenic artery branches into the short gastric artery, left gastroepiploic artery, and posterior gastric artery, which supplies blood to the stomach, spleen, and pancreas.

How many branches are there in the short gastric artery?
The short gastric arteries consist of from five to seven small branches, which arise from the end of the splenic artery, and from its terminal divisions. They pass from left to right, between the layers of the gastrolienal ligament, and are distributed to the greater curvature of the stomach, anastomosing with branches of ...
What is the name of the artery that raises the stomach?
The celiac artery and its branches; the stomach has been raised and the peritoneum removed. (Short gastric visible at center right.) The short gastric arteries consist of from five to seven small branches, which arise from the end of the splenic artery, and from its terminal divisions. They pass from left to right, ...
Do short gastric arteries have anastomoses?
Unlike the gastroepiploics and the left and right gastric arteries, the short gastric arteries have poor anastomoses if the splenic artery is blocked.
What are the branches of the left and right gastric arteries?
(Top) In “conventional” arterial anatomy of the stomach and duodenum (present in only 50% of the population), the left gastric artery arises from the celiac trunk, supplies the lesser curvature, and anastomoses with the right gastric artery, a branch of the proper hepatic artery.
What are the branches of the celiac artery?
Catheter arteriogram with injection of the celiac artery shows its main branches (left gastric, splenic, and common hepatic). The lesser curvature of the stomach is supplied by the left and right gastric arteries, with the latter being a branch of the proper hepatic artery. The greater curvature is supplied by the right and left gastroepiploic arteries, branches of the gastroduodenal and splenic arteries, respectively. The splenic artery also supplies short gastric arteries to the fundus. The gastroduodenal artery gives rise to the superior pancreaticoduodenal arteries, which anastomose with branches from the superior mesenteric artery to provide a rich vascular supply to the pancreas and duodenum. There are numerous congenital variations in the blood supply to the upper abdominal organs, and many interconnecting pathways of the celiac and superior mesenteric arteries and their branches.
What is the largest nerve plexus?
The celiac plexus is the largest major autonomic nerve plexus. It surrounds the celiac trunk and the origin of the superior mesenteric artery near the duodenojejunal junction, in front of the aorta. The plexus is comprised of the celiac, superior mesenteric, and aorticorenal ganglia.
Which veins drain from the stomach, spleen, and pancreas?
Tributaries that drain from the stomach, spleen, and pancreas: short gastric vein, left gastroomental vein, and pancreatic veins that merge into the inferior mesenteric vein. The inferior mesenteric vein joins with the splenic vein that merges with the superior mesenteric vein to become part of the hepatic portal vein.
Which nerve exchanges fibers with the splanchnic and celiac plexuses?
The gastric and gastroepiploic arteries are surrounded by the rich celiac plexus ( Fig. 26.8) that arises principally from the vagus nerve. The anterior vagus nerve exchanges fibers with the splanchnic and celiac plexuses. All vascular manipulations of the stomach involve its nervous system.
Which artery is the right gastric artery?
The right gastric artery arises from the proper hepatic artery. •. The left gastroepiploic artery is a branch of the splenic artery. •. The gastroduodenal artery gives off the right gastroepiploic artery. All of this makes up the vascular circle of the stomach.
Which artery branch is the most common?
Gastric and gastroepiploic artery aneurysms are the most common of the celiac artery branch aneurysms, representing 4% of visceral aneurysms. 88 Gastroduodenal and pancreaticoduodenal artery aneurysms are less common, accounting for 1.5% to 3% of visceral aneurysms ( Fig. 88.7 ). 80,88 When associated with pancreatitis, most arise in men, usually in the fifth decade of life. 80
What is the supply of the stomach?
Arterial supply to the stomach. The stomach is supplied by a rich system of arteries derived from the celiac trunk, the first major visceral branch of the abdominal aorta. The lesser curvature of the stomach is supplied by the left and right gastric artery, which are branches of the celiac trunk and the common hepatic artery respectively.
Which artery supplies the stomach?
The fundus and upper part of the body of the stomach is supplied by the short and posterior gastric branches of the splenic artery while the pylorus of the stomach is supplied by the gastroduodenal artery, a branch of the common hepatic artery.
Which arteries are responsible for the lesser curvature of the stomach?
The lesser curvature of the stomach is supplied by the left and right gastric artery, which are branches of the celiac trunk and the common hepatic artery respectively. The greater curvature is supplied by the left and right gastro-omental (gastro-epiploic) arteries, which originate from the splenic and gastroduodenal arteries respectively. ...
What is the term for the inner lining of the stomach?
A disruption of this physiologic balance leads to damage of this inner lining, known as a peptic ulcer.
What causes bleeding in the upper gastrointestinal tract?
Peptic ulcers are the most common cause of upper gastrointestinal bleeding. The loss of blood can occur over a long period of time, leading to anaemia, or it can be rapid, resulting in haemodynamic compromise – a situation which requires urgent medical and surgical intervention.
What is the meaning of anastomosis?
Each of these pairs of arteries form an arterial anastomosis, which means the arteri es come together and share a supply territory ?. This is an important organization, as blood will still be delivered to a particular territory, even if one of its many arteries are occluded, which is most commonly seen in older patients.
Structure
Blood supply to the stomach: left and right gastric artery, left and right gastro-omental artery and short gastric artery.
Function
The short gastric arteries supply the fundus of the stomach on the side of the greater curvature of the stomach. [2]
