Your Question

My husband is 38-years-old, and we just found out he has fibromuscular dysplasia (FMD). He had a stroke 6 months ago. My question is, how long before he has another stroke? Can this take his life?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is the recurrence risk for stroke in fibromuscular dysplasia (FMD)?

Specific recurrence risks for stroke in FMD are not available. Case reports suggest that treatment with medicines and angioplasty can reduce the risk of recurrent stroke.[1]

Can fibromuscular dysplasia (FMD) be life-threatening?

In rare cases, FMD-related aneurysms can burst and bleed into the brain, causing stroke, permanent nerve damage, or death.[1] Certain treatment can help reduce the risk of life-threatening complications of FMD. Patients with minimal narrowing of blood vessels may take a daily aspirin or an anticoagulant to thin the blood and reduce the chances that a clot might form. Patients with arterial disease who smoke should be encouraged to quit as smoking worsens the disease. Further treatment may include angioplasty, in which a small balloon is inserted through a catheter and inflated to open the artery. Small tubes called stents may be inserted to keep arteries open. Surgery may be needed to treat aneurysms that have the potential to rupture and cause bleeding within the brain.[1]
