title: Endovascular treatment of bilateral common iliac artery aneurysms using bifurcated-unibody stent grafts.
abstract: BACKGROUND
  Endovascular treatment of bilateral common iliac artery aneurysms (CIAA) is a promising alternative to open surgical repair. However, endovascular treatment is challenging when the CIAAs have short proximal necks and internal iliac artery needs to be preserved.
  
  
  RESULTS
  We report a case of a 62-year-old man who presented with bilateral CIAA with short proximal necks, with the right-side aneurysm extended into the internal iliac artery. The aneurysms were successfully excluded by using a bifurcated-unibody stent graft on the left with preservation of its internal iliac artery; a conventional tubular covered stent was used on the right with occlusion of its internal iliac artery. In addition, an aorta-bi-iliac artery stent was used to provide extended proximal landing zones for the iliac stents.
  
  
  CONCLUSIONS
  Endovascular repair using an iliac bifurcated-unibody stent graft can be a useful approach for the treatment of CIAAs. An aorta-bi-iliac endograft may also be needed to provide a reliable landing zone when the proximal neck of the iliac aneurysm is short.
