[Serial hepatic and splenic volumetry in acute severe hepatitis].

In this study, we elucidate a relationship between final outcome and changes in hepatic and splenic volume in patients with acute severe hepatitis. The subjects were 40 patients: 10 with sever acute hepatitis (prothrombin time < 40%) and 30 with fulminant hepatic failure (acute type in 12 and subacute type in 18). Liver and spleen volume were measured by CT initially on hospitalization and subsequently 1 to 40 days after hospitalization, and the scans were analyzed retrospectively. Liver volume decreased in 15 of 26 survivors, and all 14 non-survivors. Among 15 survivors and 14 non-survivors whose liver volume decreased, spleen volume increased in none of the survivors, whereas it increased in 11 of the 14 non-survivors. In survivors there was a close parallelism between changing rates of the liver volume and that of the spleen volume (r = 0.82, p < 0.0001). These observations suggest that the decrease of liver volume accompanied by that of spleen volume implies a good prognosis, while the decrease without such accompaniment implies a bad prognosis.
