Chimney technique for solitary pelvic kidney

Abstract

The combination of solitary pelvic kidney and abdominal aortic aneurysm is extremely rare. In this report, we present chimney graft implantation in a patient with solitary pelvic kidney. A 63-year-old man had the diagnosis of infrarenal abdominal aortic aneurysm made incidentally. Preoperative computed tomography illustrated a fusiform abdominal aortic aneurysm accompanying a solitary ectopic kidney in the pelvis with aberrant renal artery. A bifurcated endograft was implanted, and a covered stent graft was placed into the renal artery by use of the chimney technique. Good patency of the chimney graft was documented with early postoperative and first month scans. To the best of our knowledge, this is the first report of the chimney technique used in a solitary pelvic kidney.
