Abstract

Objective: To study the anatomical characteristics of the left gastric artery (LGA) on 64-slice computed tomography (CT). Methods: A cross-sectional descriptive study was conducted on 385 cases who underwent 64-slice abdominal CT at the Department of Diagnostic Imaging, Binh Dan Hospital, from September 2024 to April 2025. Results: Among 385 study samples, the origin of the LGA from the celiac trunk accounted for 91.9% of cases. In more than 61% of cases, the LGA was located from the lower third of the 12th thoracic vertebra (T12) to the upper third of the 1st lumbar vertebra (L1). The diameter of the LGA was 2.66 ± 0.31 mm, and its length was 30.33 ± 9.25 mm. In 77.1% of cases, the observed branches of the LGA were mainly type I. The distance from the abdominal aorta to the LGA was 19.65 ± 6.06 mm. Conclusion: This study provides essential information to help surgeons identify appropriate anatomical landmarks when performing dissection, clamping, and vessel transection in gastric surgery or endovascular interventions involving the LGA. It may also aid in selecting suitable catheters when accessing via the LGA.
