Fibromuscular Dysplasia

Official Community

Fibromuscular dysplasia (FMD) is a disease of the artery wall, without atherosclerosis (cholesterol deposits) or inflammation present. Sometimes this can lead to an arterial stenosis (narrowing), a dilation (aneurysm) or a dissection (tear) of the affected artery. A stenosis or a dissection can be responsible for a reduction in arterial blood flow. The effect of this reduced blood flow depends on the location of the arteries involved.
