Definition
The prepyloric vein (vein of Mayo), is a small vein that drains the pyloric region of the stomach. It typically runs along the anterior surface of the pylorus and drains into the right gastric vein or directly into the portal vein. This vein is often used as a landmark in surgical procedures involving the stomach, such as gastrectomies, due to its consistent location near the pylorus.
