left gastric vein
Noun: * A branch of the portal venous system: The left gastric vein is a blood vessel that collects deoxygenated blood from a specific region of the stomach. * Specific anatomical pathway: It originates from veins near the top of the stomach (gastric cardia), travels within a fold of tissue called the lesser omentum, and drains into the portal vein, which carries blood to the liver.
The term "left gastric vein" is used exclusively in medical, anatomical, and biological contexts to describe a specific part of the human circulatory system. * The surgeon carefully ligated the left gastric vein during the procedure. * A key anatomical landmark is where the left gastric vein empties into the portal vein. * The study examined blood flow variations in the left gastric vein.
- Clinical Significance: In medical contexts, the left gastric vein is important in understanding conditions like portal hypertension, where increased pressure in the portal system can cause this vein to enlarge and form risky varices (swollen veins) in the esophagus.

- Coronary Vein: This is an older or alternative name for the left gastric vein. The two terms are often used synonymously in anatomical literature.
