Background: Pseudoaneurysm formation sometimes complicates transplant nephrectomy. We report a case of bleeding from a pseudoaneurysm after transplantation nephrectomy that resulted in shock and emergency endovascular treatment.
Case presentation: A 56-year-old man underwent transplant nephrectomy 3 years and 9 months following transplantation for pyelonephritis-related infection control. On postoperative day 7, he developed sudden pain in the lower abdomen and subsequently went into shock. A pseudoaneurysm at the anastomosis was detected, and urgent endovascular treatment was performed to stem the bleeding.
Conclusion: Vascular complications, including pseudoaneurysms, following transplant nephrectomy can be life-threatening, and comprehensive awareness is needed in careful postoperative management.
Keywords: kidney transplant nephrectomy; pseudoaneurysm; transplant kidney infection; vascular complication; vascular reconstruction.
