Irreversible Electroporation(IRE) For Unresectable Portal Venous Tumor Emboli

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

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety (adverse effects) | adverse effects | 6 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Efficacy (percentage of lesions that show no sign of recurrence 12 months after IRE) | The primary objective of this project is to evaluate the efficacy (percentage of lesions that show no sign of recurrence 12 months after IRE） | 12 months |
