Abstract
Anatomical variations of the left gastric artery (LGA) and right gastric artery (RGA) are clinically relevant for gastric surgery and endovascular interventions. This study aimed to characterize the origin, anatomical distribution and morphometric features of the LGA and RGA using 64-slice computed tomography (CT). A cross-sectional descriptive study was conducted on 385 individuals who underwent contrast-enhanced abdominal CT at Binh Dan Hospital between September 2024 and April 2025. The LGA originated from the celiac trunk in 91.9% of cases and was most frequently located between the lower one-third of T12 and the upper one-third of L1 (> 61%). Its mean diameter and length were 2.7 ± 0.3 mm and 30.3 ± 9.3 mm, respectively, with the Type I branching pattern predominating, characterized by branches supplying the oesophagus, gastroesophageal junction and the lesser curvature. The mean distance from the abdominal aorta to the LGA was 19.6 ± 6.1 mm. The RGA was identified in 88.3% of cases and most commonly arose from the proper hepatic artery (72.9%), with a mean diameter of 1.6 ± 0.2 mm. An arterial arcade along the lesser curvature was observed in 81.3% of cases. These findings provide quantitative anatomical data that may support accurate identification of vascular landmarks during gastric surgery and facilitate appropriate catheter selection for endovascular procedures involving the LGA and RGA.
