Fibromuscular dysplasia (FMD) is a unique vascular condition that isn’t caused by atherosclerosis or inflammation. It mainly impacts medium-sized arteries, especially the renal and carotid ones. When the walls of these arteries grow abnormally, it can lead to issues like narrowing (stenosis), bulging (aneurysm), or even tearing (dissection). Patients might experience symptoms such as high blood pressure, headaches, or brief episodes of reduced blood flow (transient ischemic attacks), depending on which arteries are affected. Recognizing FMD early is crucial to avoid serious complications like strokes or kidney problems.
To diagnose FMD, doctors usually rely on imaging methods such as duplex ultrasound, CT angiography, MR angiography, or catheter-based angiography to spot the typical changes in the arteries. Treatment can involve procedures like percutaneous angioplasty, managing blood pressure with medication, and careful monitoring. With prompt treatment, patients can keep their vascular health in check, manage their symptoms, and lower the chances of severe vascular issues.
