Changes in hepatic functional reserve after transcatheter embolization of hepatocellular carcinoma. Assessment by maximal removal rate of indocyanine green.
To clarify the influence of transcatheter arterial embolization (TAE) on hepatic function, the maximal removal rate of indocyanine green (ICG-Rmax), which represents the hepatic functional reserve, and the plasma disappearance rate of indocyanine green (k-ICG) were measured serially before and after 15 TAE procedures performed on 13 hepatocellular carcinoma (HCC) patients with underlying hepatic diseases. Compared to the values before TAE, ICG-Rmax values did not change or gradually decreased during 4 weeks in seven of the 13 patients but markedly decreased in the remaining six by as much as 50% during the first week. k-ICG values remained almost unchanged at any time after TAE. Albumin and prothrombin time were serially measured before and after 24 TAE procedures performed on 21 HCC patients with underlying hepatic diseases in whom no plasma products had been used for therapy. Albumin decreased by up to 75% in one of the 21 patients during the first week but did not change or gradually decreased in 20 of the 21 patients. Prothrombin time showed no obvious changes. This study showed that prominent changes occurred in ICG-Rmax, i.e., in the hepatic functional reserve, after TAE.
