Right gastro epiploic vein

The right gastroepiploic vein is a significant blood vessel located in the abdomen. It runs parallel to the right gastroepiploic artery and is an essential part of the venous drainage system of the stomach.

Originating from the greater curvature of the stomach, this vein receives blood from various branches, including the short gastric veins. As it continues its course, it eventually joins with the superior mesenteric vein, contributing to the portal venous system. Understanding the anatomy and function of the right gastroepiploic vein is crucial for medical professionals in diagnosing and treating related conditions, ensuring proper circulation and overall digestive health.

The right gastroepiploic vein is essential in many surgical procedures:

  • Gastric Bypass and Gastric Cancer Surgery: The RGEV may require ligation or resection in gastrectomy procedures. Surgeons should be cautious of potential bleeding risks and the implications for vascular flow.
  • Coronary Artery Bypass Grafting (CABG): Surgeons often use the right gastroepiploic artery as a graft, though the associated vein is also considered during CABG preparation due to its proximity and importance.
  • Trauma and Emergency Surgery: Understanding Right gastroepiploic vein anatomy aids in identifying bleeding sources, especially in abdominal injuries.
