Fibromuscular dysplasia (FMD) is a disorder that affects the walls of blood vessels. It's non-atherosclerotic and non-inflammatory, meaning fatty buildup in the vessels or inflammation cause it.
Abnormal growth, called fibroplasia, forms in the artery walls, causing them to narrow or look beaded.
At the UPMC Division of Vascular Surgery, we take a team approach to diagnosing FMD quickly and correctly. Then, we design a treatment plan tailored to your unique needs.
