title: Endovascular treatment of renal aneurysms: a series of 18 cases.
abstract: OBJECTIVE
  To retrospectively analyze the results and complications of the endovascular treatment of 18 renal aneurysms.
  
  
  METHODS
  From 2002 to 2011, 15 patients (aged 31-76), with 18 renal aneurysms, were admitted in our institution for treatment by embolization. Except one, all were wide-necked aneurysms. One aneurysm was treated by occluding the parent artery considering its distal location; a small-necked aneurysm was treated by simple coiling, and the remaining 16 were embolized utilizing adjunctive techniques to protect the parent artery. We analyzed the rates of technical success, complication and clinical consequence, post-operative occlusion and recurrence.
  
  
  RESULTS
  There was a 100% technical success rate. 15 aneurysms showed a total occlusion on the post-treatment angiogram. 2 aneurysms demonstrated neck remnants, and one had an intrasaccular residual in-flow. Two minor post-operative complications were encountered but resolved over time. No delayed clinical complications were observed and the long-term angiographic follow-up demonstrated stability of the occlusion of the target renal aneurysm with no major recurrence.
  
  
  CONCLUSIONS
  Complications of the embolization of renal aneurysms are rare. Endovascular treatment should therefore be considered at first for the treatment of renal aneurysms.
