Giant aneurysm of venous aorto-right renal artery bypass

This is a case of a young woman who was admitted to our department with a diagnosis of 'aneurysm of aorto-right renal artery venous bypass' performed for a diagnosis of Takayasu arteritis, left renal artery occlusion, right renal artery subocclusion and abdominal aorta coarctation. The patient had previously undergone extra-anatomical bypass between the descending thoracic aorta and the subrenal abdominal aorta and a venous bypass between abdominal aorta and right renal artery. A new bypass with an 8-mm-armed polytetrafluoroethylene graft was performed between the right renal artery and the right common iliac artery. The postoperative period was uneventful and the patient was then discharged. At 2-year follow-up, the angio-computed tomography (angio-CT) scan showed the patency of the bypass between the right common iliac artery and the right renal artery.
