title: Endovascular Repair of Renal Artery Anastomotic Pseudoaneurysm Following Living Donor Kidney Transplant.
abstract: Renal artery anastomotic pseudoaneurysms, an uncommon complication of transplantation, may result in aneurysm rupture and loss of allograft. We report the case of 50-year-old female with back pain 3 weeks post renal transplantation. CT scan revealed transplant renal artery anastomotic pseudoaneurysm arising from anastomosis of two renal arteries joined together to form a single renal artery that was joined to the aorta. Successful endovascular treatment was achieved with covered stents, resulting in preserved renal function. Follow-up ultrasound at one-day post procedure and CT at 2 months revealed satisfactory renal perfusion with no pseudoaneurysm. Endovascular treatment of transplant renal artery pseudoaneurysms with covered stent and ostial flare balloon technology may be preferred in patients with extensive prior pelvic surgery, as illustrated in this case.
