Percutaneous microwave coagulation therapy with interruption of hepatic artery

Abstract

Six patients with unresectable hepatocellular carcinoma were received percutaneous microwave coagulation therapy (PMCT) during interruption of hepatic artery. After the tumor was detected by angiogram and angio-CT, patients received one to several times of PMCT with 60W and 60 seconds under intravenous anesthesia or epidural anesthesia. In only one patient, abdominal bleeding and right hemothorax were observed though she was conservatively recovered. There were no serious complications in laboratory data. We had complete tumor necrosis, and complete response in all 6 cases. The serum level of alfa-fetoprotein was normalized in 4 patients, and reduced markedly in other patients. PMCT was very useful for unresectable hepatocellular carcinoma.
