Fracture of a left atrial catheter made of polyethylene and its subsequent embolization and entrapment in a Bjork-Shiley aortic valvular prosthesis is reported in a 62-year-old woman. The entrapped fragment of the catheter was retrieved by a transarterial approach using a homemade modified snare-loop device. Measures to prevent such a complication should be directed towards avoidance of force when removing such catheters. In addition, their length should be determined prior to insertion and again after removal, in order to detect their possible fracture and loss at once.
报道了一名62岁女性患者，其左心房聚乙烯导管发生断裂，随后导管碎片栓塞并嵌顿于Bjork-Shiley主动脉瓣膜假体中。通过经动脉途径使用自制改良圈套环装置取出了嵌顿的导管碎片。预防此类并发症的措施应针对在拔除此类导管时避免用力。此外，在插入导管前和拔除后均应测量其长度，以便立即发现导管可能发生的断裂和丢失。
