Clinical and experimental studies on portal vein embolization / Diagnosis of hepatocellular adenoma and focal nodular hyperplasia

The first part of this thesis concerns liver regeneration after portal vein embolization (PVE). The use of PVE over the past 20 years is reviewed and its effect on tumor growth and (postresectional) hypertrophy response discussed. The effects of several portal vein occlusion techniques are evaluated in experimental studies using a rabbit model of PVE. The second part of this thesis deals with two liver tumors, hepatocellular adenoma (HCA) and focal nodular hyperplasia (FNH), which are relatively rare, benign liver tumors. The main focus is on differentiation of these tumors using current imaging modalities.
