Abstract

Introduction. Computed tomography is the most common diagnostic method for pathological changes in the abdominal organs in institutions providing routine and emergency medical care. Computed tomography is increasingly becoming a method for assessing the condition of blood vessels, including in patients with portal hypertension, which requires assessment of the condition of the veins of the esophagus and stomach.The purpose of the study. Determination of the optimal technique for performing computed tomography to study the gastric veins.Materials and methods. The results of studies of 1562 patients who underwent various computed tomography techniques in medical institutions in Moscow from December 2020 to December 2023 were retrospectively assessed. The research results are archived in the unified radiological information system (RIS) in Moscow.Results. 1051 patients were examined using the standard multiphase computed tomography technique. The topographic and anatomical characteristics of the gastric veins were determined just in 50.01% of cases due to the collapsed state of the stomach. 78 studies were carried out after taking oral contrast agents, veins were identified in 37.44% of cases. The difficulty of imaging is determined by the presence of hyperdense contrast agent in the gastric lumen. After gastric inflation with air, the results of a study of 52 patients were assessed. Positive visualization of gastric veins was obtained in 45% of patients. 381 patients underwent computed tomography with the stomach filled with water (hydro-CT). Normal veins measuring 1 or more millimeters in diameter were visualized and localized in 60.6–72.5% of patients, which is significantly better compared to the standard research method (p < 0.001).Conclusion. Assessment of the condition of the gastric veins should be carried out using the hydro-CT technique, which significantly improves the assessment of the topographic and anatomical features of the vessels compared to the standard CT technique.
