Summary
A rare anatomical variation was found where the left gastric artery originated directly from the abdominal aorta. This finding is important for surgical procedures involving the upper abdomen and stomach.
Area of Science:
- Anatomy
- Embryology
- Vascular Surgery
Background:
- Anatomical variations in ventral splanchnic arteries can occur due to unusual embryologic development.
- The left gastric artery typically arises from the celiac trunk.
- Variations in the origin of the left gastric artery are documented but rare.
Observation:
- During a cadaver dissection, a 48-year-old male presented with an anomalous origin of the left gastric artery.
- The left gastric artery was observed to arise directly from the anterior surface of the abdominal aorta.
Findings:
- This case details a rare variation in the arterial supply to the stomach.
- The reported incidence of such variations ranges from 0.5% to 15%.
Implications:
- Understanding this variation is crucial for surgeons performing procedures on supracolic organs.
- Accurate anatomical knowledge is vital for stomach resections and lymph node dissection in gastric cancer surgery.
- This variation may impact surgical planning and execution, potentially altering blood supply during operations.
