Left Gastroepiploic Artery[edit]

The left gastroepiploic artery is a significant blood vessel that supplies blood to the stomach and the greater omentum. It is one of the branches of the splenic artery, which itself is a branch of the celiac trunk.

Anatomy[edit]

The left gastroepiploic artery arises from the splenic artery near the hilum of the spleen. It travels along the greater curvature of the stomach, running between the layers of the greater omentum. As it courses along the stomach, it provides numerous branches that supply the stomach wall and the omentum.

The artery anastomoses with the right gastroepiploic artery, which is a branch of the gastroduodenal artery. This anastomosis forms an important collateral circulation around the stomach, ensuring adequate blood supply even if one of the arteries is compromised.

Function[edit]

The primary function of the left gastroepiploic artery is to supply oxygenated blood to the stomach and the greater omentum. The greater omentum is a large fold of visceral peritoneum that hangs down from the stomach, providing protection and immune support to the abdominal organs.

Clinical Significance[edit]

The left gastroepiploic artery is often used in coronary artery bypass grafting (CABG) due to its size and length. Surgeons may harvest this artery to create a bypass around blocked coronary arteries, restoring blood flow to the heart muscle.

Injuries or diseases affecting the left gastroepiploic artery can lead to compromised blood supply to the stomach, potentially resulting in gastric ischemia or ulcers. Understanding its anatomy is crucial for surgical procedures involving the stomach and spleen.

-==Etymology==
+The '''left gastroepiploic artery''' is a significant blood vessel that supplies blood to the stomach and the greater omentum. It is one of the branches of the [[splenic artery]], which itself is a branch of the [[celiac trunk]].
-The term "gastroepiploic" is derived from the Greek words "gaster" meaning stomach, and "epiploon" meaning omentum. The term "artery" comes from the Latin "arteria", meaning a windpipe or artery, which in turn is derived from the Greek "ἀρτηρία" (artēría), a word used by Hippocrates to denote windpipe or artery.

-The left gastroepiploic artery arises from the [[splenic artery]], which is a branch of the [[celiac artery]]. It runs from left to right along the greater curvature of the stomach, between the layers of the greater omentum, anastomosing with the [[right gastroepiploic artery]], a branch of the [[gastroduodenal artery]].

-The left gastroepiploic artery is of clinical significance in several surgical procedures, including gastric bypass surgery and the creation of a [[gastric tube]] for esophageal replacement. It is also important in the diagnosis and treatment of [[gastric cancer]] and [[peptic ulcer disease]].
