Answer

Conventional aortography produces excellent radiographic images of the renal artery, but it requires an arterial puncture, carries the risk of cholesterol emboli, and uses a moderate amount of contrast material with the risk of contrast-induced acute tubular necrosis (ATN). Low osmolar contrast material can limit the risk of this complication. Complication rates for renal angiography are 6-10% in most series.
