Abstract Objective: To investigate ultrasonic imaging features of hepatic veins and collateral circulations in Budd-Chiari syndrome(BCS) in Henan Province. Methods: Sonograms of 567 patients with BCS were analyzed. Results: ①There were 517 branches of middle hepatic vein(MHV) had pathological changes, 507 branches of left hepatic vein(LHV) had pathological changes and 418 branches of right hepatic vein(RHV) had pathological changes. The main lesion type of LHV and MHV was membranous occlusion. The main lesion type of RHV was streak-like stenosis. ②There were 403 patients with dilated accessary hepatic veins(AHVs) in 567 patients with BCS. In them, there were 27 branches with pathological changes. There was a significant difference in AHVs with or without pathological changes between unobstructed inferior vena cava(IVC) and obstructed IVC(P=0.000, continuity correction). ③There were 8 types of collateral circulation. ④There were 395 patients with collateral circulation wiehin liver in 567 patients with BCS. There was a significant difference in collateral circulation with MHVs between caudate lobe veins and right posterior veins(P=0.000). ⑤There were 331 branches of LHV with collateral circulation, 319 branches of MHV with collateral circulation and 104 branches of RHV with collateral circulation. There was a significant difference in collateral circulation between LHV, MHV and RHV(P=0.000). There was no a significant difference in collateral circulation between LHV and MHV(P=0.234). There was a significant difference in collateral circulation between LHV and RHV(P=0.000). There was a significant difference in collateral circulation between MHV and RHV(P=0.000). Conclusions: ①The features of MHVs of BCS in Henan Province of China which had a high affection rate, more dilated AHVs and collateral circulations in liver. ②There are abundant types of collateral circulation in liver of patients with BCS. There are more collateral circulations between caudate lobe veins and MHVs than that between right posterior veins and MHVs. There are more collateral circulations of LHV and MHV than that of RHV. The main affection category of MHVs concerned with quantity of collateral circulation. ③Some AHVs have pathological changes. The affection of IVC is not the major factor for AHVs.
