Three commercial vessel dilators and a dilator of an improved design were tested during percutaneous catheterization in 16 mongrel dogs to evaluate arterial damage produced with their use. The results indicate that, although all dilators often produce arterial damage, the improved design produced much less damage. In addition, lesions were less severe overall. The dilator has been safely and successfully used in patients for percutaneous vessel catheterization for the past 30 years at the authors' institution.
在对16只杂种犬进行经皮导管插入术期间，测试了三种商用血管扩张器和一种改进设计的扩张器，以评估使用它们时产生的动脉损伤。结果表明，尽管所有扩张器通常都会造成动脉损伤，但改进后的设计造成的损伤要小得多。此外，总体病变也不那么严重。在作者所在机构，过去30年来，这种扩张器已安全、成功地用于患者的经皮血管导管插入术。
