External iliac artery endofibrosis (EIAE)
Rare. Narrowing of lumen of external iliac artery. Pain mimics many musculoskeletal conditions delay in diagnosis of non-diagnosis.
Described in young athletes
The endofribotic changes are rarely sufficient to cause symptoms when demand for blood is not high. When demand high ‘claudication’ symptoms
Vague lower limb pains; numbness; loss of muscle power; normal ABI at rest
Taylor & George (2001) compared the ankle-brachial pressure index (ABI) in normal subjects and cyclists complaining of exercise induced leg pain (EILP) of unknown origin before and after exercise on a cycle ergometer to exhaustion. They concluded that in those with EILP that in the first minute after exercise that an ABI less than 0.5 or unilateral difference in ABI of 0.18 or is a useful diagnostic criterion that warrants further investigation.
