External Iliac Artery Endofibrosis
External iliac artery endofibrosis (EIAE) usually occurs in cyclists. Typical symptoms are leg pain and weakness caused by damage to the arteries of the pelvis, groin or lower leg. This damage appears to cause the arteries to stretch, narrow or kink in such a way that during high-intensity exercise the athlete experiences decreased blood flow due to the constriction or obstruction of the artery in the affected leg. This lack of blood flow causes pain, burning, weakness, and powerlessness during exercise. Ultrasound used in conjunction with exercise pressure testing can reveal whether or not there is any narrowing of the external iliac artery and drop in ankle brachial indices confirming arterial insufficiency.
The patient will need to bring a bicycle and wind trainer. Testing takes approximately 30 minutes.
