Successful treatment of renovascular hypertension due to fibromuscular dysplasia by intravascular ultrasound-guided atherectomy.
A 22-year-old man presented with renovascular hypertension, based on a stenosis of the distal portion of the right renal artery with a "string of beads"-like appearance. An intravascular ultrasound image at the renal artery lesion revealed irregularity of the vascular wall. Directional atherectomy was performed and histopathology of atherectomised tissues showed medial fibroplasia, a common type of fibromuscular dysplasia. After atherectomy his hypertension was markedly improved. We report here a case of renovascular hypertension due to fibromuscular dysplasia, successfully diagnosed and treated with IVUS-guided renal atherectomy.
