Summary
Fibromuscular dysplasia is a condition affecting arteries, often the renal and carotid. Treatment focuses on symptomatic lesions, with catheter intervention for simple cases and surgery for complex ones, yielding long-term results.
Area of Science:
- Vascular Medicine
- Arterial Diseases
Background:
- Fibromuscular dysplasia (FMD) is a multifactorial arteriopathy affecting small and medium-sized arteries.
- Commonly impacts the renal and internal carotid arteries.
- Pathological classification depends on the arterial wall layer affected.
Purpose of the Study:
- To summarize the understanding of fibromuscular dysplasia, including its pathology, clinical presentation, and treatment outcomes.
Main Methods:
- Review of existing literature on fibromuscular dysplasia.
- Classification based on arterial wall layer involvement.
- Analysis of treatment strategies for symptomatic lesions.
Main Results:
- The natural history and incidence of asymptomatic fibromuscular dysplasia remain unknown.
- Symptomatic lesions commonly manifest as high-grade stenosis causing renovascular hypertension or cerebral embolism.
- Catheter-based intervention is effective for simple lesions, while surgery is indicated for complex cases.
Conclusions:
- Treatment is reserved for symptomatic fibromuscular dysplasia lesions.
- Both interventional and surgical approaches offer durable, long-term results for affected patients.
