Anaya Taboada M, Cabellero-Tovar D, Patiño Jaramillo N, Garcia Lopez A, Girón Luque F. Graft transcatheter embolization in patients with renal graft intolerance syndrome: 3 case reports in a transplant group. Rev. Colomb. Nefrol. [Internet]. 2022 Jul. 7 [cited 2024 Jul. 16];9(2). Available from:


Background: The renal graft intolerance syndrome is an inflammatory process that occurs in one third of the kidney transplant patients with graft loss. If medical treatment for intolerance graft syndrome is not effective, there is an indication of graft nephrectomy. However, graft nephrectomy has higher morbidity and mortality compared to non-invasive techniques. Due to a high fragility in kidney transplant patients, the renal arterial embolization has become a useful minimally invasive therapeutic option for intolerance graft syndrome.

Objective: We aim to describe the use of renal arterial embolization for renal graft intolerance syndrome.

Case presentation: We report three clinical cases who were admitted to the emergency department for a history of twenty days of graft pain and swelling. These patients had fever, hyporexia, weight loss and macroscopic hematuria. None of the cases had clinical improvement with immunosuppression adjustment and a diagnosis of renal graft intolerance syndrome was made dismissing infection. Patients were treated with renal arterial embolization and its procedure success were determined as the symptom’s resolution.

Discussion and conclusion: After 24- and 48-hours post-embolization, patients were successfully recovered and discharged in the hospital. Renal graft arterial embolization is a safe and non-invasive alternative to graft nephrectomy to treat renal intolerance syndrome.
