A Case of Infective Endocarditis Complicated with Mycotic Aneurysm of Superior Mesenteric Artery / 감염

ABSTRACT

Mycotic aneurysm of mesenteric artery is an uncommon complication of infective endocarditis. Early diagnosis is important and surgical intervention is often needed for effective treatment of mycotic aneurysm of mesenteric artery because of the high incidence of aneurysmal rupture. We experienced a case of infective endocarditis complicated with mycotic aneurysm of the superior mesenteric artery in a 54-year old man, who was admitted because of pain on the right lower quadrant of abdomen. Echocardiography showed mitral regurgit-ation and vegetations on the mitral valve and viridans streptococcus was identified from blood cultures. He was successfully treated with ceftriaxone and gentamicin for the initial 2 weeks, then ceftriaxone alone for two weeks more without surgical intervention. To our knowledge, this is the first case of infective endocarditis complicated with superior mesenteric artery aneurysm in Korea.
