The correlation of categorical or continuous variables was analyzed by Spearman correlation test. In determining the maximum diameter of a vessel, isolated saccular dilatation of a vessel in venous ectasia or venous aneurysm was excluded. LGV: Left gastric vein; SGV: Short gastric veins; PGV: Posterior gastric vein.
