Four incidents of catheter separation in three patients during left heart catheterization and coronary angiography are presented. In two cases the catheters had been used before. After the second incident, we decided to use angiography catheters once only. All catheter fragments were removed under local anesthesia, and no further complications arose. In all incidents the point of catheter fracture was near the bond between the body of the catheter and its tip. We believe that catheter separation is related to polymer aging. The catheters in the third and fourth incidents were unused, but there was no expiration date on their packages. We recommend that expiration dates be clearly stated on every catheter package, catheter manufactures issue warnings not to use catheters after expiration date, and unused angiography catheters with no expiration date not be used. We also suggest that consideration be given to using catheters once only.
本文介绍了3例患者在左心导管插入术和冠状动脉造影过程中发生的4起导管分离事件。其中2例使用的是用过的导管。在第二起事件后，我们决定导管仅使用一次。所有导管碎片均在局部麻醉下取出，未出现进一步并发症。在所有事件中，导管断裂点均靠近导管主体与其尖端的连接处。我们认为导管分离与聚合物老化有关。第三起和第四起事件中的导管未使用过，但包装上没有有效期。我们建议在每个导管包装上明确标明有效期，导管制造商发布警告，禁止在有效期后使用导管，并且不使用没有有效期的未用过的血管造影导管。我们还建议考虑导管仅使用一次。
