Abstract:
Objective To evaluate the changes of hepatic blood perfusion of liver cirrhosis patients and the role of pericardial devascularization (PCDV)on them.Methods Hepatic artery and portal vein perfusions of 22 liver cirrhotic patients (LC) pre and post P CDV compared with control were evaluated with rheohepatogram(RHG) and ultrasonogram(USG).Results Compared with control,both hepatic and portal effective perfusion of LC were decreased on RHG, PCDV could increase portal perfusion of LC patients without significant effect on hepatic artery.USG showed that portal vein diameter and blood quantity of LC increased and PCDV didn't influence liver perfusion;No correlation between RHG and USG parameters were seen by STATA analysis. Conclusions RHG is an effective way to evaluate comprehensive blood perfusion of cirrhotic livers,the effect of operation on blood perfusion and prognosis.
