Abstract:
A 53-year-old man suffering from infectious endocarditis developed a rupture of the mitral valve tendinous cord. Consequently a mitral valvoplasty was performed. Forty days later, the patient presented with sudden and severe epigastralgia and hematemesis, and was rushed to our hospital. An arterial phase of an abdominal contrast-enhanced CT showed a mass 3 cm in diameter which was strongly enhanced along the side of the hepatic portal region and therefore it was thought to be an aneurysm. An abdominal angiography revealed an aneurysm of the right hepatic artery. As a result, an embolization with coils was performed. Nine months after treatment, CT examination of the abdomen revealed that the aneurysm had completely disappeared.
