Renal Fibromuscular Dysplasia: A Not So Common Entity of Secondary Hypertension

Abstract

Fibromuscular dysplasia is a rare noninflammatory vascular disease characterized by nonatheroslerotic stenosis predominantly seen in young women, whereas the majority of cases involve the renal arteries causing secondary hypertension. Most noninvasive screening tests are not quite sensitive or reproducible to rule out renal artery stenosis, but renal angiography usually confirms the diagnosis. Percutaneous renal artery angioplasty is the treatment of choice; however, it may not result in normalization of blood pressure if diagnosis is delayed. Continued follow-up is necessary since stenosis reoccurs.
