Overview
The definition of Fibromuscular Dysplasia(FMD) on the Medical Subject Headings is "an idiopathic, segmental, nonatheromatous disease of the musculature of arterial walls, leading to stenosis of small and medium-sized arteries. There is a true proliferation of smooth muscle cells and fibrous tissue formation. however, this systemic arteriopathy is a noninflammatory process and is therefore not associated with inflammatory biomarkers.
According to the definition, FMD is a condition which can involve every vascular bed in the body, therefore it can cause very heterogeneous and extensive spectrum of clinical manifestations from asymptomatic involvement to devastating consequences and morbidity and mortality.
Unlike routine conception that FMD is a rare disease of middle-aged female, current data from the French and US registries showed that the awareness about FMD must be raised, and every health provider at any level should be familiar with suggestive symptoms and signs of FMD which is more frequent and more often systematic than previously thought.
Historical Perspective
Fibromuscular dysplasia was first discovered by Leadbetter and Burkland, in 1938 following evaluation of severe hypertension in a 5-year-old boy. The first histopathological description of fibromuscular dysplasia and pathologic classification for this condition was proposed in 1958 and 1971 by McCormack and coworkers.
Fibromuscular dysplasia with involvement of extrarenal arteries has been considering in recent years. However numerous aspects of molecular biology and genetic etiology of this condition remain unanswered, and there are various top research priorities in the field of FMD to improve our understanding of this condition.
