ABSTRACT
A 71-year-old woman who had Takayasu's disease underwent Y-grafting, bypass grafting between the abdominal aorta and left renal artery with 8mm ePTFE graft and right nephrectomy for infrarenal abdominal aortic aneurysm and renovascular hypertension (RVH). Four years after the first operation, the bypass graft became occluded and hypertension was exacerbated. Magnetic resonance angiography revealed that the left renal artery was supplied by the collateral arteries. We performed replacement of the thoracoabdominal aorta and reconstruction of the left renal artery using the saphenous vein. Postoperatively serum creatinine level decreased and hypertension was controllable. She was discharged from the hospital and has been well for three years.
ABSTRACT
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 <i>Salmonella</i> infection. We evaluated there 3 cases and an additional 14 cases reported in the Japanese literature. Eleven patients with <i>Salmonella</i> infection had bacteremia. The incidence of bacteremia in patients with <i>Salmonella</i> 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 <i>in situ</i> 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 <i>Salmonella</i> infection.
