CHAPTER 93: Donor Evaluation

Magnetic resonance images showing a retro-aortic left renal vein. The left renal vein traverses behind the aorta in approximately 1–2% of cases. This variant occurs when the dorsal (rather than the ventral) arch of the aortic collar remains patent.

A common trunk is shown with a green arrow. The anterior branch is shown with a yellow arrow. Circumaortic renal veins have an incidence of ~3%, and represent remnants of paired supracardinal veins.
