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 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.
- Aneurysms. When your arteries are narrowed, the blood flow can weaken the wall 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.
