title: Association of crossed renal ectopia and aortic aneurism. Case report.
abstract: OBJECTIVE
  Renal malformations are rare entities and rarely have clinical consequences. Crossed renal ectopia has an incidence of 1/2.000 autopsies. The association with aortic aneurysm is even more exceptional.
  
  
  METHODS
  We present our case and perform a bibliographic review.
  
  
  RESULTS
  To date and in our knowledge, seven cases of crossed renal ectopia associated with aortic aneurysm were described on the literature. This malformation makes the treatment of the aneurysm more complex. The possibility of renal function decrease caused by injuries to the renal arteries during the surgical procedure is always present. Because of this risk of injury of the kidney during surgery preoperative evaluation of the vascularization must include image technologies as the MRI, CT-angiography or conventional arteriography. During the aortic intervention vascular conservation must be performed and it is necessary to minimize the time of renal ischemia.
  
  
  CONCLUSIONS
  The association of crossed renal ectopia and aortic aneurysm is a rare event. The surgical intervention of the aorta does not have to necessarily originate a loss of renal function. Anyway the worsening of the renal clearance must be foreseen.
