説明
Hepatic functional reserve after portal embolization was assessed in eight patients according to the functional volume index (FVI), a new index obtained using positron emission tomography (PET) withl-[methyl-11C] methionine. FVI in residual liver was 1744–5252 (mean, 3441) (normal range, 3106–6211) before percutaneous transhepatic portal embolization (PTPE) and 2457–6906 (mean, 4590) after PTPE. FVI exceeded 4000 in five patients and did not reach 4000 in three patients after PTPE. Two patients with FVI values of more than 4000 survived after hepatectomy and one with FVI under 4000 died of liver failure. FVI is a useful criterion for determining indications for PTPE; a value exceeding 4000 is needed before major hepatectomy can be safely performed after PTPE.
