"True" mycotic aneurysm of the anastomotic site of the renal allograft artery.

The incidence of vascular complications after renal transplant as reported varies from 3.5% to 14%. Pseudoaneurysm formation at the site of the anastomosis is a rare complication, and only a few cases have been reported. There also were only a few reports of "true" mycotic aneurysms of the renal allograft artery. We present 2 patients with true mycotic aneurysmal formation of the renal allograft artery after a renal transplant. Both patients presented with fever and increasing serum creatinine levels. Cultures from aneurysm tissue samples have grown Aspergillus flavus. Both patients were subjected to an allograft nephrectomy, and amphotericin was given.
