title: Apical entry of single main renal artery.
abstract: Two cases of extrahilar entry of a single main renal artery are described. Selective renal angiography demonstrated arterial entry through the upper pole of the kidney and venous exit, adjacent to the arterial entry. Embryologic as well as some surgical aspects are presented. To our knowledge only one similar variation of arterial supply to the kidney has been reported previously.
