Origin: Left gastric artery.
Course: Pass beneath the visceral peritoneum superiorly to the abdominal esophagus.
Branches: None.
Supplied Structures: Abdominal esophagus.
Origin
The first branch of the celiac trunk is the left gastric artery. From the proximal part of the left gastric artery, 1–3 small branches emerge to supply the esophagus.
Course
The esophageal branches of the left gastric artery pass retroperitoneally in a superior direction to the abdominal esophagus. They may pass through the esophageal opening of the diaphragm to include the distal-most thoracic esophagus.
Branches
The esophageal branches give rise to small penetrating branches that pass through the connective tissue layer of the esophagus and contribute to the intramural and submucosal capillary plexuses.
Supplied Structures
The esophageal branches of the left gastric artery supply the abdominal esophagus and may include some small portion of the distal thoracic esophagus.
