Angiography of the radial artery via distal radial sheath revealed a significant stenosis and dissection at the previous puncture site of the radial artery (Fig. 1A, Suppl. Because of her small radial artery (about 2-3 mm in diameter), a 0.014 system was chosen and the angioplasty was performed with a peripheral balloon (SLEEK  OTW0.014" percutaneous transluminal angioplasty catheter, 2.0 x 150 mm, Cordis, USA) without a guiding catheter (Fig. 1B). After percutaneous transluminal angioplasty, a final angiography revealed acceptable results (Fig. 1C). And then, right snuffbox puncture site sheath was removed and hemostasis was successful (Fig. 1D, E).
