Intravascular ultrasound, performed using a 0.018 in guide wire with a 30 MHz ultrasound transducer, allows to study the acute recoil of Palmaz-Schatz stent. This case showed that the acute recoil of the Palmaz-Schatz stent occurs immediately after stent implantation. The analysis of diameter and lumen cross-sectional area at the stent site was performed at different levels of dilatation. A 20% reduction of cross-sectional area was found immediately after stent expansion and balloon deflation.
血管内超声检查采用带有30MHz超声换能器的0.018英寸导丝进行，可用于研究Palmaz-Schatz支架的急性回缩情况。该病例显示，Palmaz-Schatz支架的急性回缩在支架植入后即刻发生。在不同扩张水平下对支架部位的直径和管腔横截面积进行了分析。在支架扩张和球囊放气后即刻发现横截面积减少了20%。
