Role of interventions in renal artery fibromuscular dysplasia: Where we are

Fibromuscular dysplasia is a rare noninflammatory vascular disease predominantly affecting the renal arteries. It is a rare cause of hypertension accounting for 10% of cases of renovascular hypertension. The classical angiographic appearance of 'string of beads' seen in medial fibroplasia type which is most common. There are various imaging modalities for diagnosis but conventional angiography is still considered as gold standard. The various treatment option includes medical therapy, interventional revascularization of renal arteries and rarely surgical. Percutaneous angioplasty is the treatment of choice in patients of renal artery fibromuscular dysplasia with hypertension. Various studies concludes 40-50% cure rate of hypertension by percutaneous angioplasty. Early diagnosis and treatment is important to achieve good long-term results.
