IRE of HCC with robotic assistance

This case study presents a 62-year-old male patient with liver cirrhosis and a 3.4 x 3.0 cm HCC in segment IVa. Using robotic-assisted IRE (Irreversible Electroporation) with simultaneous needle placement and robotic guidance, the procedure achieved complete ablation with no peri- or post-interventional complications. The use of Perfint.MAXIO system allowed for semi-automatic needle placement and precise positioning, while avoiding the need for CT fluoroscopy. Follow-up scans confirmed successful ablation in CEUS, MRI, and CT.
