Infectious arterial aneurysm in a rare condition with a high mortality because of rapid aneurysmal growth and subsequent rupture. We encountered 3 cases of arterial aneurysm due to Salmonella infection. We evaluated there 3 cases and an additional 14 cases reported in the Japanese literature. Eleven patients with Salmonella infection had bacteremia. The incidence of bacteremia in patients with Salmonella infection was more frequent than that in patients with other bacillary infections. The location of the aneurysm was the abdominal aorta in 14. Rupture or impending rupture of the aneurysm was identified in 12. Fifteen patients underwent operation including in situ reconstruction in 9 and extra-anatomic bypass in 6. Among 15 patients who underwent an operation, 14 survived. These data suggest that accurate preoperative diagnosis, long-term antibiotic therapy, and immediate surgical intervention are essential for effective treatment of arterial aneurysm due to Salmonella infection.
