title: Sequential coil embolization of bilateral internal iliac artery aneurysms prior to endovascular abdominal aortic aneurysm repair.
abstract: OBJECTIVE
  To report the endovascular repair of concomitant aneurysms of the abdominal aorta and both internal iliac arteries.
  
  
  METHODS
  A 72-year-old man with a 5.5-cm abdominal aortic aneurysm (AAA) extending to the right common iliac artery also presented with separate aneurysms of both internal iliac arteries. The patient refused conventional surgery, so an endovascular strategy was devised. Initially, the iliac aneurysms were sequentially coil embolized, allowing several weeks to elapse between the embolization sessions to encourage collateral development. A bifurcated Talent endograft was inserted successfully 8 months after the initial intervention; no evidence of endoleaks or mesenteric ischemia has been seen over a 1-year follow-up.
  
  
  CONCLUSIONS
  This case illustrates the feasibility of inducing collateralization prior to endovascular AAA repair that would jeopardize internal iliac artery circulation bilaterally. Sequential embolization of the internal iliac arteries over several months initiates this response, paving the way for eventual endovascular repair of the primary aortic aneurysm.
