Abstract:
Objective To summarize sonographic classification of blood-drainage in Budd-Chiari syndrome (BCS)with hepatic vein(HV)obstruction in order to provide much information for clinical treatment.Methods A total of 185 patients with HV obstruction were underwent sonographic examination.The affection of HV,the courses,orifices,blood flow direction of drainage viens,the communicating branches among HVs and draining viens were observed detailedly.Classification of blood-drainage pattern were performed by sonogram in accordance with digital subtraction angiography(DSA)and computed tomography angiography(CTA).Results There were 490 HVs with affection in 185 patients.The blood drainage pattern were classified as the following six types:HV-accessory HV(AHV)type(119/185),HV-HV type(31/185),HV-AHV/HV type(14/185),inferior caval vein (IVC)-AHV-HV-right atrium type(9/185),HV-umbilical vein type(5/185)and HV-hepatic subeapsular vein type (7/185).Blood of obstructed HVs was drainaged to IVC,right atrium,umbilical veins or hepatic subcapsular veins through communicating branches which were in various amount and diameter.Haemodynamics was obtained from drainage veins correspondingly.Conclusions Sonographic classification of blood-drainage pattern in BCS with hepatic vein obstruction is of important clinical significance in the treatment.
