Occlusion of the Popliteal Artery in Hereditary Multiple Exostosis Syndrome

AbstractIntroductionHereditary multiple exostosis syndrome is a rare condition which can occasionally cause arterial occlusion.Case reportA 50-year-old man was treated for acute leg ischaemia but no cause found. Two years later, acute ischaemia recurred and attempts at limb salvage failed. Hereditary multiple exostosis syndrome was then recognised as the cause due to a femoral exostosis compressing the popliteal artery.DiscussionThe case highlights a rare cause of acute limb ischaemia and emphasises the importance of arterial imaging when no embolic source is found
