Aim To determine whether diameters of the left gastric vein ( LGV ) and its originating vein are associated with endoscopic grades of esophageal varices. Methods Ninety‐eight liver cirrhotic patients with hepatitis B undergoing magnetic resonance ( MR ) portography, and upper gastrointestinal endoscopy for grading esophageal varices were enrolled. Diameters of the LGV and its originating vein – the splenic vein ( SV ) or portal vein ( PV ) – were measured on MR imaging. Statistical analyses were performed to identify the association of the diameters with the endoscopic grades. Results Univariate analysis showed that the SV was predominantly the originating vein of the LGV , and diameters of the LGV and SV were associated with grades of esophageal varices. Diameters of the LGV ( P = 0.023, odds ratio [ OR ] = 1.583) and SV ( P = 0.012, OR = 2.126) were independent risk factors of presence of the varices. Cut‐off LGV diameters of 5.1 mm, 5.9 mm, 6.6 mm, 7.1 mm, 7.8 mm and 5.8 mm; or cut‐off SV diameters of 7.3 mm, 7.9 mm, 8.4 mm, 9.5 mm, 10.7 mm and 8.3 mm, could discriminate grades 0 from 1, 0 from 2, 0 from 3, 1 from 3, 2 from 3, and 0–1 from 2–3, respectively. Conclusion Diameters of the LGV and SV are associated with endoscopic grades of esophageal varices.
