Potential risks of bilateral internal iliac occlusion

Bilateral internal iliac occlusion due to a stent graft can result in some potential complications:

  1. Gluteal claudication and necrosis in severe cases
  2. Erectile dysfunction
  3. Bowel ischemia
  4. Bladder ischemia
  5. Spinal cord ischemia

Coil embolisation of internal iliacs is resorted to for preventing type II endoleak when the aortic stent grafts needs to be extended into the external iliac arteries.
