External iliac artery endofibrosis is an uncommon, nonatherosclerotic disease seen in endurance cyclists. It is poorly identified by providers. These otherwise healthy patients usually present with symptoms of arterial insufficiency, such as thigh or buttock pain, loss of power, or weakness occurring during strenuous exercises. These symptoms subside rapidly with rest. As these patients lack traditional risk factors of peripheral artery disease, their symptoms are often overlooked or are attributed to other etiologies, resulting in mismanagement and delayed treatment. In this case study, we report our experience with the successful management of a 48-year-old male who is a longstanding, avid cyclist. He self-referred to our institution after extensive research of providers familiar with his problem and at the recommendation of other cyclists with similar experiences. The patient underwent a successful left external iliac to common femoral artery endarterectomy and patch angioplasty. Three months after operation, he returned to cycling and, for the most part, has remained without symptoms.
