Microwave coagulonecrosis (MCN) was performed percutaneously for hepatocellular carcinoma (HCC), after transcatheter arterial chemoembolization (TACE).
(Case-1) The patient was a 55-year old man with type-B chronic hepatitis for 10 years. Tumors were found in S7 (3 cm) and S8 (4 cm) segment of liver. Percutaneous MCN was performed 4 and 6 weeks after lipiodol-TAE. CT-guided percutaneous transpulmonary MCN was useful for the HCC in S7, which was not revealed with ultrasonography. Posttreatmental hemopneumothorax did not require any treatment.
(Case-2) The patient was a 69-year old woman with type-C liver cirrhosis. After TAE, CT-guided percutaneous transthoracic MCN were done for the HCC (2 cm) in S8-4. In order to avoid the pulmonary injury, right pneumotorax was prepared deliberately. The course of two patients after the treatments was very excellent. The complementary therapy of TACE and percutaneous MCN is minimally invasive and may be very effective treatment of HCC.
