Aortoiliac Occlusive Disease (AIOD)

Aortoiliac occlusive disease (AIOD) is common in patients with PAD. AIOD is the blockage of the aorta, the main blood vessel in your body, or the iliac arteries. The aorta divides into the iliac arteries, which provide blood to the legs and organs in your pelvis. This blockage is typically caused by a buildup of plaque within the walls of the blood vessels.


Common AIOD symptoms include:

  • Persistent or intermittent leg/thigh/buttock pain (claudication) or cramping when walking
  • Numbness or loss of sensation in the affected limb
  • Sores that heal slowly or fail to heal
  • Differences between limbs in relation to color and/or warmth
  • Decreased rate of hair and nail growth on the impacted limb
  • Foot pain at rest
  • Erectile dysfunction
