[Complication of therapeutic transcatheter hepatic artery embolization for hepatoma--case of developing an extensive acute gastric ulcer].

We report the development of an extensive acute gastric ulcer in a 60-year-old man following therapeutic transcatheter hepatic artery embolization for hepatoma. The unintentional occlusion of branches of the right gastric artery with refluxed Gelfoam fragments is thought to be responsible. This complication is probably rare, but should be kept in mind when therapeutic embolization of the hepatic artery is performed.
