|Other names: External iliac artery endofibrosis (EIAE)|
Iliac artery endofibrosis (IAE) is a type of endofibrosis (thickening of the inside) of the external iliac artery. Symptoms may include pain or weakness of the leg with heavy exercise. Complications may include acute limb ischemia.
Risk factors include sports that involve repeated movement of the hips such as cycling. Diagnosis may be supported by a decrease in the ankle brachial index to less than 0.66 after exercise and confirmed by ultrasound, CT angiogram, or a MR angiogram.
Treatment may involve stopping the sport that is causing the issue. Angioplasty and vascular stenting do not appear useful.
