The Safety and Efficacy of Irreversible Electroporation for the Treatment of Perivascular Liver Cancers

The irreversible electroporation ablation system (Irreversible Electroporation Ablation Generator) used in this study delivers an ablation field with a voltage of 3,000 volts. It received U.S. Food and Drug Administration (FDA) approval in 2023 but has not yet been introduced in Taiwan. This study will target participants with malignant liver tumors who are unsuitable for surgical resection but are eligible for local ablation therapy, specifically those with tumors located adjacent to the inferior vena cava, hepatic veins, or within 1 cm of the main trunks of both portal veins. A total of 20 participants will undergo ablation treatment under intubation and general anesthesia. Postoperative monitoring will focus on potential complications, and participants will be followed for four months to assess complete tumor ablation and intrahepatic recurrence, in order to verify the clinical feasibility and advantages of this system.
