IPAs following kidney transplantation are most often mycotic in etiology, but have been sporadically reported to result from Pseudomonas aeruginosa infection. These IPAs occur at various anatomic sites, most commonly at the vascular anastomosis or iliac artery, and very rarely in the transplanted renal artery or hilum. Here we report the occurrence of single donor-derived P aeruginosa IPAs in two kidney transplant recipients with divergent allograft outcomes. Both recipients manifested Pseudomonas infections and early, hemodynamically relevant postoperative hemorrhage as a result of pseudoaneurysm rupture. One recipient required allograft nephrectomy during emergent operative exploration due to rupture of a pseudoaneurysm at the vascular anastomosis. Conversely, the other recipient's allograft was salvaged by endovascular stenting of a pseudoaneurysm unusually located in the main donor renal artery. To the best of our knowledge, this is the first case of a ruptured IPA occurring in the transplanted renal artery with successful allograft salvage via endovascular technique. In this report, we discuss details of the two cases, relevant literature, and possible clinical implications.1 aBerger, MF1 aBadell, IR  uhttps://www.notifylibrary.org/reference/4788
