Fibromuscular dysplasia synonyms

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disease of the blood vessels that is most commonly referred to by its modern name, though it has historically been known as "fibromuscular hyperplasia." While medical literature occasionally references older terms like "medial fibroplasia," the term Fibromuscular dysplasia is the standardized nomenclature used by clinical experts and international health organizations today to ensure diagnostic consistency.

Why does Fibromuscular dysplasia have multiple names?

The naming of Fibromuscular dysplasia has evolved alongside our understanding of its pathology. Historically, because the disease involves the abnormal growth of cells in the arterial wall, it was frequently categorized under broader terms related to "hyperplasia" (an increase in cell number). As imaging technology improved—specifically the ability to visualize the "string-of-beads" appearance in the renal and carotid arteries—researchers realized the condition was more complex than simple tissue overgrowth. This led to a transition toward the term "dysplasia," which better describes the abnormal development or structural disorganization of the arterial wall. Today, the medical community avoids older, ambiguous terms to prevent confusion with other vascular inflammatory conditions like vasculitis.

What are the official medical classifications for Fibromuscular dysplasia?

To ensure accuracy in electronic health records and international research, Fibromuscular dysplasia is categorized using several standardized coding systems. These identifiers are crucial for patients searching medical literature or verifying their diagnosis:

• Orphanet: Classified under ORPHA:333 (Fibromuscular dysplasia of arteries).


• OMIM (Online Mendelian Inheritance in Man): Referenced as #135580.


• ICD-10-CM: Identified by code I77.3.


• ICD-11: Categorized under code BC60.0.

Are there different subtypes or historical terms used in clinical literature?

While Fibromuscular dysplasia is the umbrella term, you may encounter specific descriptive names in older medical journals or specialized vascular reports. These names often describe the specific layer of the artery affected or the visual appearance of the vessel:

1. Medial Fibroplasia: The most common form, accounting for approximately 80% to 90% of cases, often presenting with the classic "string-of-beads" appearance.


2. Intimal Fibroplasia: A rarer form that often appears as a focal, tubular stenosis, more commonly seen in younger patients.


3. Adventitial Fibroplasia: The rarest form, involving the outermost layer of the artery.


4. Fibromuscular Hyperplasia: An archaic term that is no longer recommended but may still appear in older pathology reports.

Which term should patients use when communicating with doctors?

When speaking with your healthcare team, it is best to use the term Fibromuscular dysplasia. This is the preferred terminology recognized by the Society for Vascular Medicine and the American Heart Association. Using the current, standardized name ensures that your medical records are accurately indexed and that your care team is referencing the most up-to-date clinical guidelines. With 132 members currently in the DiseaseMaps community living with this condition, using consistent terminology helps patients share experiences and access relevant support resources more effectively.

Next steps

• Confirm your diagnosis by requesting a copy of your vascular imaging report, which should explicitly state "Fibromuscular dysplasia."


• Consult with a vascular specialist or a cardiologist who has specific experience treating FMD.


• Join the DiseaseMaps community to connect with others who are managing the same diagnosis.


• Visit the NIH GARD website to stay updated on current research and patient advocacy efforts.
