We performed 300 consecutive coronary arteriographies with 2 different kinds of catheters: polyurethane catheters and polyethylene catheters. The thromboembolic complication rate for investigations with each type of catheters is compared to the surface structure as seen with the scanning electron microscope (SEM). The complication rate was 21.4% for polyurethane catheters and 0.3% for polyethylene catheters. The inner surface of polyurethane catheters was irregular, while the inner surface of polyethylene catheters appeared smooth. The outer surface of polyurethane catheters was slight irregular, while the outer surface of polyethylene catheters was smooth. These results are compared to other investigations of the surface structure of coronary catheters and to reports on the thromboembolic complication rate at coronary arteriography. It is concluded that the 2 types of catheters have different thrombogenic properties and that the surface structure is of major importance for this difference.
我们使用两种不同类型的导管——聚氨酯导管和聚乙烯导管，连续进行了300例冠状动脉造影。将每种类型导管检查的血栓栓塞并发症发生率与扫描电子显微镜（SEM）观察到的表面结构进行比较。聚氨酯导管的并发症发生率为21.4%，聚乙烯导管为0.3%。聚氨酯导管的内表面不规则，而聚乙烯导管的内表面看起来光滑。聚氨酯导管的外表面略有不规则，而聚乙烯导管的外表面光滑。将这些结果与其他关于冠状动脉导管表面结构的研究以及冠状动脉造影时血栓栓塞并发症发生率的报告进行比较。得出的结论是，这两种类型的导管具有不同的血栓形成特性，并且表面结构对这种差异至关重要。
