A 66-year-old woman was operated on aortic valve replacement, mitral valve replacement, and tricuspid annuloplasty. Retrieval of remaining Swan-Ganz Thermodilution catheter in the superior vena cava and the right atrium for 15 years was also made. Fortunately, contamination and embolism have not occurred for 15 years. Extracted catheter showed to be stiff due to the degradation. It was suggested that the cause of remaining was the thread for closing the left atrium on the previous operation. The explanation to patient and one's recognition are most important. We recommend that retrieval of remaining catheter for a long time and/or after open heart surgery should be made under extracorporeal circulation because that remaining catheter may be involved with the intima, and preventing from bleeding.
一名66岁女性接受了主动脉瓣置换术、二尖瓣置换术和三尖瓣环成形术。还取出了留在上腔静脉和右心房长达15年的Swan-Ganz热稀释导管。幸运的是，15年来未发生感染和栓塞。取出的导管因降解而变硬。推测残留的原因是上次手术时用于关闭左心房的缝线。向患者解释并取得其认可最为重要。我们建议，长时间留存的导管和/或心脏直视手术后残留的导管应在体外循环下取出，因为残留导管可能与内膜粘连，并存在出血风险。
