Irreversible Electroporation(IRE) For Unresectable Portal Venous Tumor Emboli

Irreversible Electroporation(IRE) For Unresectable Portal Venous Tumor Emboli: Phase I and Phase II Clinical Trial

The purpose of this study is to evaluate the safety and efficacy of irreversible electroporation (IRE) for unresectable Portal venous tumor emboli.

By enrolling patients with unresectable Portal venous tumor emboli adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of percutaneous or intraoperative IRE for unresectable Portal venous tumor emboli.
