Abstract: Objective The purpose of this study was to investigate prediction of esophageal gastric varices (EV/GV) by abdominal CT scan parameters in patients with liver cirrhosis (LC) and portal hypertension. Methods 110 patients with LC and portal hypertension were encountered in our hospital between January 2021 and December 2025, and all patients underwent electronic gastroscopy. Abdominal CT scan was conducted to measure hepatic and splenic parenchyma iodine concentrations, and gastric coronary vein (GCV) diameter. Predicting efficacy was evaluated by receiver operating characteristic (ROC) curve. Results Of the 110 patients with LC, gastroscopy found mild EV in 61 cases, and moderate to severe EV/GV in 49 cases; iodine concentrations in left lobe, right lobe, caudate lobe of the liver, and splenic parenchyma as well as diameter of GCV in patients with moderate to severe EV/GV were (5.9±1.1)mg/ml, (5.6±0.7)mg/ml, (6.1±0.9)mg/ml, (20.4±1.5)mg/ml and (5.5±0.8)mm, all significantly higher or greater than [(5.1±0.7)mg/ml, (5.0±0.4)mg/ml, (5.5±0.5)mg/ml, (17.7±1.2)mg/ml and (3.6±0.5)mm, respectively, P＜0.05] in those with mild EV; the sensitivity, specificity and accuracy were 77.6%, 83.6% and 80.9%, when diameter of GCV≥4.7 mm, iodine concentrations in caudate lobe of liver≥5.8 mg/ml and splenic parenchyma≥19.2 mg/ml were set as the cut-off-value in predicting moderate to severe EV/GV. Conclusion Abdominal CT scan could help judge EV/GV existence in patients with LC.
