Stroke secondary to FMD
Alternative namesFibromuscular dysplasia - stroke secondary to
DefinitionDamage to brain tissue caused by fibromuscular dysplasia, an inherited disorder that leads to the destruction of arterial blood vessels which can cause bleeding in the brain.
Causes, incidence, and risk factors
Stroke secondary to fibromuscular dysplasia (FMD) primarily affects women, especially those older than 50.
The disease may affect the neck arteries that supply blood to the brain (carotid) or the arteries within the brain (cerebral) and cause stroke. It may also affect the following arteries:
Secondary symptoms include high blood pressure , leg pain , heart attack , kidney failure , and other disorders.
Risks include a personal or family history of FMD.
Signs and testsThe exact location and extent of the stroke , and changes in the arteries indicating FMD including berry aneurysms (small ballooned-out areas of the artery), may be seen on:
An arteriography/ angiography of the head may show blood vessel changes such as narrowing of the arteries.
An artery biopsy confirms the diagnosis of FMD (this is not performed on cranial blood vessels).
TreatmentThere is no known treatment for fibromuscular dysplasia.
Evaluation and treatment of hypertension ( high blood pressure ) associated with kidney disorders may be appropriate in some people with stroke secondary to FMD.
See Stroke .
Expectations (prognosis)The outcome is often poor regardless of the extent of the stroke . FMD is associated with early death.
ComplicationsSee Stroke .
Calling your health care providerGo to the emergency room or call the local emergency number (such as 911) if symptoms occur.
PreventionAwareness of personal or family history of FMD can allow earlier diagnosis of the cause of stroke and can avoid damage caused by inappropriate treatment.
