title: Ectopic origin of main renal artery.
abstract: Two cases with an unusually high origin of a single main left renal artery, angiographically investigated, are presented. In the first case the artery originates as the most cephalad branch of the abdominal aorta above the celiac artery. In the second case its origin is from the celiac axis. Embryologic as well as some practical aspects are mentioned.
