[Case of primary aorto-jejunal fistula caused by gram-positive cocci]

A 46 year-old man was transferred to our department with a pulsating abdominal mass and back pain. On arrival he suddenly developed hematemesis. CT suggested the presence of an infrarenal aortic aneurysm and the jejunum was filled with contrast medium. An emergency operation was done. We found an aorto-jejunal fistula at the branching point of the renal artery. We directly sutured the aortic wall laceration and the jejunum wall in two layers. Then we resected infrarenal pseudoaneurysm as completely as possible, with replacement by a Dacron Y-shaped prosthesis. Culture of the aortic wall showed gram-positive cocci, but the species could not be identified. Gram stain of the aortic wall also showed infection by gram-positive cocci. The patient is alive and well 3 months after surgery.
