Splenic arterial steal syndrome (SASS) is a significant complication after liver transplantation.However, even in chronic liver cirrhosis patients without undergone liver transplantation, the phenomenon of SASS also can be observed.On celiac trunk angiography, SASS is presented as early hyperperfusion of dilatated splenic artery associated with delayed hypoperfusion of constricted hepatic artery.This paper aims to assess the severity of liver cirrhosis and determine the presence of chronic cirrhosis-related SASS by using proper hepatic artery diameter to splenic artery diameter ratio (HSR).In the study, HSR and relative enhancement (RE) of liver parenchyma on Gd-EOB-DTPA-enhanced MR were used to measure the severity of liver cirrhosis expressed as MELD score.The optimal cutoff value of HSR or RE for distinguishing patients with healthy liver group to patients with MELD score≤10 group, MELD score 11-18 group and MELD score>18 group were calculated,respectively.A high MELD score might be predicted by decreased of HSR, serum albumin, platelets count and increased of serum ALT, presence of ascites.In conclusion, HSR might be used to measure the severity of liver cirrhosis.A low HSR value indicates the presence of SASS especially in those patients with high MELD score.
