    Abstract:
    A case in which rupture of a hepatic artery aneurysm occurred 4 months after aortic valve replacement because of aortic regurgitation due to infective endocarditis (IE) is reported. The patient was a 41-year-old male who underwent aortic valve replacement and closure of an abscess cavity of the Valsalva's sinus because of aortic regurgitation and an abscess of the Valsalva's sinus complicated with active IE. His postoperative course was good with no fever. Four months postoperatively, rupture of an aneurysm of the left intrahepatic artery occurred suddenly, and the patient's life was saved by resection of the lateral segment of the left lobe of the liver. Histologically, the wall structure of the aneurysm was not preserved, infiltration of neutrophils was seen in part of the wall, and a mycotic aneurysm of the left hepatic artery within the liver cause by IE was diagnosed. In Japan, only four cases, including the present one, of mycotic aneurysm of the hepatic artery have been reported in the literature examined, and this was the first case in which the patient's life as saved after a rupture. It is essential when observing the course of IE patients to bear in mind at all times that such a complication might occur.
