Hepatic artery aneurysm in a 10-year-old boy as a complication of infective endocarditis.

Mycotic aneurysms occur from septic emboli in patients with infective endocarditis and may involve any artery, but frequently they are not detected before autopsy. The most common sites are the brain, abdominal aorta, sinus of Valsalva, ligated ductus arteriosus, and superior mesenteric, splenic, coronary, and pulmonary arteries. The authors report on a 10-year-old boy who had a mycotic aneurysm of the common hepatic artery, which developed during the course of infective endocarditis of the mitral valve and was cured successively using a platinum coil embolization technique.
