Successful stenting of bilateral renal artery stenosis due to fibromuscular dysplasia assessed by use of pressure guidewire technique: a case report.

An 18-year-old woman with renovascular hypertension had stenosis due to fibromuscular dysplasia (FMD) of the bilateral renal arteries, and this did not respond to conventional balloon angioplasty owing to marked elastic recoil. Implantation of Palmaz-Schatz stents resulted in successful dilation of the stenosis and remission of hypertension. Transstenotic pressure gradients were measured by use of a pressure-monitoring guidewire. It is suggested that stenting is a very useful adjunct to balloon angioplasty in the treatment of renal artery stenosis due to FMD.
