ABSTRACT
Objective:
To explore the value of FibroScan in liver grafts from brain-dead donors (DBD) prior to liver transplantation (LT).Methods:
Liver grafts from 52 DBD were examined using ultrasound and FibroScan before LT. The causes of death were cerebral hemorrhage ( n=25), brain trauma ( n=21) and ischemic-hypoxic cerebropathy ( n=6). Blood samples were tested before LT and a biopsy was performed pre- or intra-operation for determining pathology. The diagnostic accuracy of FibroScan results was compared with that of pathological examinations. The latter is a gold standard for evaluating liver grafts. The eligible donors were grouped by stage of liver fibrosis (F0-F4) and steatosis (S0-S3) based upon Kleiner's scoring system of nonalcoholic fatty liver disease.Results:
The value of liver stiffness (LS) significantly rose in group F1 as compared with group F0 (8.74±1.32) kPa and (5.93±1.64) kPa respectively ( P<0.01). The value of LS had a significantly positive correlation with liver graft fibrosis stage ( r=0.73, P<0.01). The area under receiver operating characteristic curve (AUROC) was 0.93 for F1 stage fibrosis ( P<0.01). Significant differences existed in controlled attenuation parameter (CAP) among groups S0, S1 and S2 (173.30±38.36), (230.29±23.27) and (250.00±57.01) dB/m respectively ( F=12.41, P<0.01). CAP was correlated with liver graft steatosis stage ( r=0.64, P<0.01). And AUROC for S1/S2 stage steatosis in liver grafts was 0.89 ( P=0.002) and 0.83 ( P=0.007) respectively.Conclusions:
With a high diagnostic accuracy, FibroScan quantifies fibrosis and steatosis in liver grafts from DBD and provides further imaging evidence for assessing liver grafts.
