Peroneal artery entrapment syndrome (PRAES): a rare cause of ischaemic toes

A 75-year-old man presenting with intermittent discolouration of his left toes was referred to vascular surgery with suspicion of embolic vascular disease. A contrast-enhanced MR angiogram was performed which revealed bilateral dominant peroneal arteries (PRAs). There was evidence of short atherosclerotic stenosis directly at the point where the left PRA passes through the tibiofibular interosseous membrane which we postulate to be the source of the emboli. We present what is believed to be the first reported case of PRA entrapment complicated by distal toe emboli.
