Efficacy and safety of percutaneous transhepatic portal embolization before right liver resection using an ethibloc/lipiodol mixture: a single-center experience.

Aim: The purpose of this study was to evaluate the safety and efficacy of percutaneous transhepatic portal vein embolization of the right portal vein with an Ethibloc/Lipiodol mixture to induce hypertrophy of the left liver lobe in patients with primarily unresectable liver tumor.

Methods: 15 patients (8 primary liver tumors, 7 liver metastases) underwent portal vein embolization. Liver volumetry, duration of hospitalization, complication rates, relevant laboratory values were documented.
