Abstract
The three directional percutaneous microwave coagulation therapy, which is the new procedure, under general anesthesia was performed for 67 y.o. male patient with HCC of 1.5 cm in diameter, in the Couinaud's segment 7 after transcatheter arterial embolization. The needle electrodes of the microwave tissue coagulator were induced through 14 gauge tru-cut biopsy needles which had been punctured from the point of 8th intercostal space (i.c.s.), from the point of 9th i.c.s. and from the point of subcostal area under ultrasonographic guidance. The microwave irradiation with dissociation electric current simultaneously was started after all the needle electrodes had been inserted. The total microwave irradiation time for this tumor counted 30 minutes.
There were no intraoperative and postoperative complications. The CT findings, 36 days after treatment, revealed that the low density area was 3.1 cm in diameter and 15.1 cm3 in volume.
Angiography and CT scan demonstrated the recurrence free 9 months after treatment.
In conclusions, this new procedure is reliable and safe for postoperative recurrent HCC.
