Prepyloric vein

Prepyloric vein

The prepyloric vein is shown in this illustration from Gray's Anatomy.

The Prepyloric vein is a blood vessel that drains the stomach and is part of the portal venous system. It is located near the pylorus, which is the part of the stomach that connects to the duodenum.

Anatomy

The prepyloric vein originates from the lesser curvature of the stomach, near the pylorus. It drains into the left gastric vein, which in turn drains into the portal vein. The prepyloric vein is accompanied along its course by the prepyloric artery.

Clinical significance

The prepyloric vein can be involved in several medical conditions. It can become enlarged in cases of portal hypertension, a condition that can lead to esophageal varices. It can also be a site of gastric bleeding, particularly in cases of peptic ulcer disease.
