ComplicationsBy Mayo Clinic staff
Fibromuscular dysplasia can cause a number of complications. These include:
- High blood pressure. A common complication of fibromuscular dysplasia is high blood pressure. The narrowing of the arteries causes higher pressure on your artery walls, which can lead to further artery damage, heart disease or heart failure.
- Chronic kidney failure. If the artery to the kidney is narrowed by fibromuscular dysplasia, you may not get enough blood flow to your kidney, causing permanent kidney injury.
- Dissected artery. Fibromuscular dysplasia can cause tears in the walls of your arteries, causing blood to leak into the artery wall. This process, called arterial dissection or spontaneous coronary artery dissection (SCAD), can limit blood flow to the organ supplied by the injured artery.
- Aneurysms. Fibromuscular dysplasia can weaken the walls of your arteries, creating a bulge called an aneurysm. If an aneurysm ruptures, it can be a life-threatening emergency. An aneurysm can occur in any artery affected by fibromuscular dysplasia.
- Stroke. If you have a dissected artery leading to your brain or if an aneurysm in an artery to your brain ruptures, you can have a stroke. High blood pressure can also increase your risk of a stroke.
