Mycotic aneurysm of the renal transplant artery

A case of mycotic aneurysm secondary to septicemia is reported. A 59-year-old man with end-stage renal failure underwent renal transplantation from a living donor. On the fifteenth postoperative day, he was febrile and his arm around an entry wound of the drip infusion had infectious signs. Cultures of the blood and pus discharge grew Methicillin-resistant Staphylococcus aureus. Vancomycin was administered intravenously for 30 days. Then the existence of a mycotic aneurysm on the transplant artery was not suspected by computed tomography. After his infectious signs disappeared, examinations revealed a pseudoaneurysm measuring 4 cm in diameter at the site of anastomosis between the renal transplant and external iliac arteries by computed tomography. He has been carefully followed up with a conservative management. This is the first case of a mycotic aneurysm treated conservatively and displaying an uneventful course without rupture.
