BACKGROUND: Pseudoaneurysm is a rare vascular complication in pancreas transplantation. This complication develops from a disruption of the arterial continuity, usually related to trauma, infection, vasculitis, or complications in vascular procedures.

CASE REPORT: A 43-year-old man underwent simultaneous pancreas and kidney transplantation for end-stage renal disease. He subsequently developed acute pancreatitis and acute kidney cellular rejection as late complications, thus returning to hemodialysis. A new, uneventful kidney transplantectomy and living donor kidney transplant was performed. One year after the last transplant, the patient presented with moderate abdominal pain, fever, and a pulsatile tumor located in the right iliac fossa. A pseudoaneurysm located in the pancreatic Y graft was observed. The patient was treated using an endovascular and surgical approach.

CONCLUSIONS: A combined procedure using an endovascular and surgical approach promoted a good vascular control with a lower risk of bleeding in a rare case of pseudoaneurysm in a transplant patient.
