Fibromuscular dysplasia is a condition that causes narrowing (stenosis) and enlargement (aneurysm) of the medium-sized arteries in your body. Reduced blood flow from narrowed arteries to the organs can affect the function of the organs.
Fibromuscular dysplasia appears most commonly in the arteries leading to the kidneys. Fibromuscular dysplasia can also affect the arteries leading to your brain, heart, abdomen, arms and legs.
Fibromuscular dysplasia can cause a number of complications, such as high blood pressure or tears of the artery (arterial dissection), if left untreated. Arterial dissection, or spontaneous coronary artery dissection (SCAD), can limit blood flow to the organ supplied by the injured artery.
While there isn't a cure for fibromuscular dysplasia, it can be treated effectively.
