Abstract
In a series of 61 adult cadavers, the posterior gastric artery was found in 38 (62.3%), originating from the superior aspect of the mid-3rd of the splenic artery. The posterior gastric artery, running behind the parietal peritoneum of the omental bursa, produced a peritoneal fold before reaching the posterior wall of the superior portion of the gastric body, near the cardiac region, and the fundus. Its high incidence, hidden origin, deep course and distribution make this artery very important for surgical procedures relating to the stomach, pancreas, spleen and celiac region. It may be crucial, especially if partial gastric resection or splenectomy have obliterated other gastric vessels.
