Revascularization of a giant right renal artery aneurysm near the hilum.

This article describes a case of a giant right renal artery aneurysm near the hilum treated with surgical excision, ex vivo renal artery reconstruction, and orthotopic autotransplantation with successful outcome. The giant right renal artery aneurysm is rare, and the successful outcome in our case report proved the safety and effectiveness of the ex vivo reconstruction in treatment of complex renal artery lesions. A 57-year-old male smoker with a history of recurrent abdominal pain was diagnosed with a 5.1-cm right renal artery aneurysm near the hilum. We chose surgical excision, ex vivo reconstruction, and orthotopic renal autotransplantation to treat this patient according to the preoperative computed tomography angiography and glomerular filtration rate. The operation was successful and the patient recovered uneventfully.
