Peripheral embolization complicating bilateral renal infarction with gelfoam

Selective arterial embolization is a technique with wide therapeutic applicability. However, regardless of the nature of the embolic particles, reflux into the aorta with peripheral embolization is a serious potential complication. A case is described in which this complication occurred. We recommend that all such embolizations be performed with a balloon catheter occluding the target artery.
