Join the next generation of care in the treatment of aortoiliac occlusive disease

Aortoiliac occlusive disease (AIOD) – An increasingly complex condition

The incidence of AIOD is increasing,1 leaving more patients vulnerable to a disease that, untreated, can cause pain, tissue loss and amputation.

  • Roughly 10% of U.S. adults (over 60 years old) are affected by peripheral arterial disease (PAD).1,2
  • Roughly 33% of PAD cases involve the iliac arteries.3

Guidelines for treating AIOD

TASC II A and B lesions:

Guidelines recommend an endovascular approach.4

TASC II C and D lesions:

Guidelines recommend surgery, although multiple consensus and practice guidelines now generally endorse an endovascular-first strategy in experienced endovascular centers.4-7


Potential obstacles of endovascular treatment


  • Tortuous anatomies
  • Severe stenosis
  • Highly calcified occlusions


  • Perforation or rupture of the iliac arteries and aortic bifurcation occurs in nearly 4% of cases and can be a life-threatening complication.8-11
  • Rupture can be difficult to identify on the final angiogram, and may occur postoperatively, causing acute bleeding and hypotension.12, 13
