Arterial cluster formation wierdness! Just when we think we've heard it all!....................
By Mayo Clinic staff
Fibromuscular dysplasia is a condition in which at least one of your arteries has an abnormal cluster of cells growing in the artery wall. This cluster causes the artery to narrow, which can cause damage to the organs that receive blood through the narrowed artery. Fibromuscular dysplasia can cause a number of complications, such as high blood pressure and a bulging area of the artery (aneurysm), if left untreated.
Fibromuscular dysplasia appears most commonly in the arteries leading to the kidneys. Fibromuscular dysplasia can also affect the arteries leading to your brain, abdomen, arms and legs. While there isn't a cure for fibromuscular dysplasia, it can be treated effectively.
