Screening for fibromuscular dysplasia (FMD). Screening for fibromuscular dysplasia (FMD). (A) Duplex ultrasonography of the right renal artery in a patient who presented with a dissection of the obtuse marginal branch of the circumflex coronary artery demonstrates severe stenosis of the mid-section consistent with FMD. (B) Duplex ultrasonography of the distal segment of the left internal carotid artery in the same patient demonstrates mild FMD. Lucy McGrath-Cadell et al.
