Blood Vessels of the Stomach, Posterior View

Description

Shown from a posterior perspective, the stomach (gaster, ventriculus) is rendered with the distal esophagus entering superiorly at the cardia and the duodenum exiting inferiorly at the pylorus. Arterial and venous channels course along the lesser curvature medially and the greater curvature laterally, then arborize across the posterior gastric wall toward the fundus superiorly and the body centrally. Blue venous tributaries track alongside their arterial counterparts, forming a dense superficial vascular pattern that follows the serosal surface and curvature-based landmarks. Orientation stays in standard anatomical terms. Posterior gastric vasculature matters because it maps directly to the named branches of the celiac trunk and the portal venous system, the routes you must respect when mobilizing the stomach or controlling hemorrhage. This angle also supports teaching of the “watershed” concept along the lesser curvature and the clinical logic behind ischemic risk after ligation of short gastric vessels during splenectomy or fundoplication. Bleeding from posterior wall peptic ulcers, classically eroding into the splenic artery territory near the fundus or into left gastric branches along the lesser curvature, becomes easier to contextualize when you can trace vessels over the posterior surface. A surgical roadmap. Use this plate in gross anatomy labs, GI surgery lectures, and exam material that asks learners to relate gastric arteries and veins to curvature, pylorus, and adjacent foregut structures. It also fits well in textbooks and patient-facing diagrams explaining sources of upper GI hemorrhage, portal hypertension related venous drainage, or operative steps in partial gastrectomy and bariatric procedures.
