The implantation of intracoronary stents is increasingly employed in interventional cardiology. Even with high-resolution x-ray equipment the tiny struts of stainless steel stents can usually not be visualized. Coronary angiography is required to prove stent patency, and correct localization and deployment of the stent can only be assessed with intravascular ultrasound. In this setting a non-invasive diagnostic method would be of great advantage to document patency of the stented vessel segment. Herein we describe two patients with stent implantation in whom contrast-medium-enhanced electron beam tomographic scanning was applied to check for vessel patency. A pathological finding with reduced contrast enhancement could be distinguished from a normal finding, as was confirmed subsequently as a highly obstructed and a patent stented vessel segment by angiography. Thus, for the first time an alternative non-invasive diagnostic method may provide information on patency of stented vessel segments and may be useful for sequential follow-up investigations.
冠状动脉内支架植入术在介入心脏病学中的应用越来越广泛。即使使用高分辨率的X射线设备，不锈钢支架的微小支柱通常也无法可视化。需要进行冠状动脉造影来证明支架通畅，而支架的正确定位和展开只能通过血管内超声进行评估。在这种情况下，一种非侵入性诊断方法对于记录支架植入血管段的通畅情况将具有很大优势。在此，我们描述了两名接受支架植入的患者，应用对比剂增强电子束断层扫描来检查血管通畅情况。造影剂增强降低的病理表现可与正常表现相区分，随后血管造影证实分别为高度阻塞和通畅的支架植入血管段。因此，一种替代性的非侵入性诊断方法首次可能提供有关支架植入血管段通畅情况的信息，并可能有助于后续的连续随访研究。
