Fibromuscular dysplasia
Fibromuscular Dysplasia (pronunciation: fy-bro-myoo-SKLER-uh-l dis-PLAY-zhuh) is a rare medical condition that causes abnormal growth or development of cells in the walls of blood vessels that can cause the vessels to narrow (stenosis), bulge (aneurysm), or tear (dissection). The term is derived from the Latin fibro meaning fiber, muscular referring to muscle, and dysplasia meaning abnormal growth or development.
Definition
Fibromuscular Dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease that primarily involves the renal and carotid arteries. It can also affect the arteries in the brain, abdomen, and extremities.
Symptoms
Symptoms of FMD can vary greatly depending on the arteries affected. They may include high blood pressure, headaches, pulsating noises in the ears, dizziness, blurred vision, neck pain, and TIA or stroke if the carotid or vertebral arteries are involved.
Causes
The exact cause of FMD is unknown. However, it is believed to be a combination of genetic, hormonal, and environmental factors. It is more common in women than in men, and it often runs in families.
Diagnosis
Diagnosis of FMD is typically made through imaging tests such as angiography, CT scan, or MRI. Blood tests may also be used to rule out other conditions.
Treatment
Treatment for FMD depends on the severity of the disease and the arteries involved. It may include medication to control blood pressure and prevent blood clots, angioplasty to widen narrowed arteries, or surgery in severe cases.
