Resumen

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease that most commonly affects the renal, carotid, and vertebral arteries. We present the case of a 40-year-old male patient with a history of recurrent transient ischemic attack (TIA). Supra-aortic computed tomography (CT) angiography revealed >80% luminal stenosis of the left carotid bifurcation and left internal carotid artery (LICA). The affected arterial segment was resected and replaced with a PTFE graft. The surgery was uneventful, achieving adequate flow restoration between the reconstructed vessels. The patient was followed in the Vascular Surgery Unit with antiplatelet agents and ultrasound (US) monitoring every six months, demonstrating adequate flow in the interposed polytetrafluoroethylene (PTFE) graft. This case highlights the value of surgical repair in symptomatic carotid FMD when endovascular treatment is unsuitable.
