[Rupture of hepatocellular carcinoma with multiple pulmonary metastasis successfully treated by transcatheter arterial embolization (TAE) of tumor: a case report].

A 66-year-old woman was hospitalized in a state of shock with rupture of hepatocellular carcinoma and multiple pulmonary metastasis. Her bleeding was successfully controlled by emergency transcatheter arterial embolization with Lipiodol (Lp-TAE). Treatments with UFT, OK-432 and two additional Lp-TAE caused the disappearance of pulmonary metastasis with AFP levels decreased and natural killer cell activity increased. The patient died one and a half years after the emergency Lp-TAE. The disappearance of pulmonary metastatic lesions seemed to be caused by improvement of the patient's immunity, which related to the regression of primary tumor after Lp-TAE. It was suggested that Lp-TAE is worth undertaking even in rupture of hepatocellular carcinoma with remote metastatic lesions.
