The greater omentum is a fold of peritoneum attached to the greater curvature of the stomach and transverse colon. Its blood supply comes from which vessels?
- A Right and left gastroepiploic (gastro-omental) arteries from the right gastric and left gastric arteries
- B Inferior mesenteric artery branches only
- C Short gastric arteries from the splenic artery
- D Right gastroepiploic (from gastroduodenal artery) and left gastroepiploic (from splenic artery) ✓
Explanation
The greater omentum receives its blood supply from the right and left gastroepiploic (gastro-omental) arteries, which run along the greater curvature of the stomach: the right gastroepiploic artery arises from the gastroduodenal artery (branch of hepatic artery proper), and the left gastroepiploic arises from the splenic artery. They anastomose along the gastroepiploic arcade. Short gastric arteries supply the fundus, not the omentum. This anatomy is important in omental pedicle flaps for defect reconstruction.
