b. Because of rich intramural collaterals, gastric viability may be preserved after ligation of all but one major artery
c. In cases of celiac artery occlusion, gastric viability is maintained collaterally via pancreaticoduodenal arcades
The stomach is an extremely well-vascularized organ, supplied by 5 major arterial distributions and protected from ischemia by rich intramural and extramural collaterals. The left gastric artery and right gastric artery, derived from the celiac distribution, supply the lesser curvature of the stomach. The right gastroepiploic artery, derived from the gastroduodenal artery, and the left gastroepiploic artery, from the splenic artery, traverse the greater curvature. The area adjacent to the spleen receives multiple short gastric arterial branches. In instances of celiac arterial occlusion, the superior mesenteric artery supplies the stomach collaterally via the pancreaticoduodenal arcades which connect with the gastroduodenal artery. The stomach may be widely mobilized for use in reconstructive procedures, for example, during trans-hiatal esophagectomy. Advantage is taken of the abundant blood supply and collaterals of the stomach during mobilization; gastric viability is usually preserved if one major arterial supply is preserved.
