Angiogram demonstrated no aortic coarctation but a tight ostial stenosis of the left renal artery (Figure 1) suggestive of possible unifocal FMD.
Plain balloon angioplasty failing to relieve the stenosis.

The stenosis was crossed and angioplastied with both 2 and 3 mm conventional balloons (Sterling, Boston Scientific, Massachusetts, United States), but there was failure to relieve the stenosis (Figure 2) despite high inflation pressures.
Cutting balloon angioplasty successfully relieving the stenosis.

Using a 6Fr sheath, an over-the-wire 3 mm x 15 mm cutting balloon (Boston Scientific) was used over a 0.014 wire (Figure 3) to relieve the stenosis.
