title: A case of right renal artery originating from the thoracic aorta.
abstract: The renal arteries normally originate from the abdominal aorta between the first and second lumbar vertebrae. The main renal artery arising from the thoracic aorta is an uncommon anomaly. Here we report a rare case of a right renal artery originating above the celiac axis. A 38-year-old male underwent computed tomographic angiography in preparation for being a renal donor, and two right renal arteries were observed. A main renal artery arose from the thoracic aorta at the 11th thoracic vertebral level, and an accessory renal artery originated from the abdominal aorta at the renal hilum.
