fibromuscular dysplasia
Also written as: FMD — Fibromuscular Dysplasia
Non-atherosclerotic arteriopathy causing stenosis, typically affecting renal and carotid arteries in young women.
Full Definition
Fibromuscular dysplasia (FMD) is a non-inflammatory, non-atherosclerotic arteriopathy that most commonly affects the renal and internal carotid arteries, though it can involve virtually any arterial bed. The condition predominantly affects women of reproductive age and is characterized by abnormal cellular proliferation within the arterial wall. The classic angiographic appearance shows alternating stenoses and dilations creating a 'string of beads' pattern, though focal stenoses can also occur. FMD can present with hypertension (renal artery involvement), stroke or TIA (carotid involvement), or be discovered incidentally on imaging.
Usage
Usage note: Commonly abbreviated as FMD in clinical documentation. Note the non-inflammatory nature when describing.
