Fibromuscular dysplasia (FMD) is a medical condition characterized by abnormal growth and development of the walls of certain arteries in the body. It primarily affects the medium-sized arteries, particularly those supplying blood to the kidneys, brain, and other vital organs. FMD can lead to various complications, including high blood pressure, aneurysms, and arterial dissections.
Synonyms for fibromuscular dysplasia include:
Medial fibroplasia refers to the abnormal thickening and fibrous tissue formation in the middle layer (media) of the arterial walls. This can cause narrowing or constriction of the affected arteries, leading to reduced blood flow to the organs they supply.
Arterial dysplasia is a general term used to describe the abnormal development or structure of arteries. In the case of fibromuscular dysplasia, the dysplastic changes primarily affect the arterial walls.
Segmental arterial mediolysis (SAM) is a rare condition that shares some similarities with fibromuscular dysplasia. It involves the destruction and thinning of the arterial walls, leading to the formation of aneurysms or dissections.
Perimedial dysplasia and periarterial dysplasia both refer to the abnormal growth and changes occurring around the media of the arterial walls.
String of beads syndrome is a descriptive term used to illustrate the appearance of affected arteries in fibromuscular dysplasia. The alternating areas of narrowing and dilation give the arteries a beaded or string-like appearance when visualized through imaging techniques.
These synonyms are often used interchangeably to describe the same underlying condition of fibromuscular dysplasia, which involves abnormal growth and structural changes in the arterial walls.
