Figure 1 (Top) Schematic representation of intravascular ultrasound (IVUS) analysis of the radial artery. Ten cross sections at 5-mm intervals were measured along 50 mm. (Bottom) Schematic representation of IVUS analysis of a radial artery cross-sectional image. IMcsa = intima-media cross-sectional area; IMT = intima-media thickness.

Figure 2 Case M.A. is a 59-year-old man. The intima-media thickness at 10 to 20 mm from the puncture site was significantly greater than that at the 40-mm segment. Case S.T. is a 73-year-old man. The 10- to 20-mm segment had a plaque-like appearance. TRI = transradial intervention.
