Abstract

Background: Recently, percutaneous cardiopulmonary support (PCPS) has been widely used to rescue patients in cardiogenic shock or cardiac arrest. However, patients with cardiopulmonary bypass (CPB) weaning failure during open heart surgery still have very poor outcomes after PCPS. We investigated clinical results and prognostic factors for patients who underwent PCPS during open heart surgery. Material and Method: From January 2005 to December 2008, 10 patients with CPB weaning failure during open heart surgery underwent PCPS using the CAPIOX emergency bypass system ($EBS^{(R)}$, Terumo Inc, Tokyo, Japan). We retrospectively reviewed the medical records of those 10 patients. Result: The average age of the patients was $60.2{\pm}16.5$ years (range, $19{\sim}77$ years). The mean supporting time was $48.7{\pm}64.7$ hours (range, $4{\sim}210$ hours). Of the 10 patients, 6(60%) were successfully weaned from the PCPS While 5 (50%) were able to be discharged from the hospital. Complications were noted in 5 patients (50%). In univariate analysis, long aortic cross clamp time during surgery, mediastinal bleeding during PCPS and high level of Troponin-I before PCPS were significant risk factors. All of the discharged patients are still surviving $34{\pm}8.6$ months (range, $23{\sim}48$ months) post-operatively. Conclusion: The use of PCPS for CPB weaning failure during open heart surgery can improve the prognosis. More experience and additional clinical studies are necessary to improve survival and decrease complications.

배경: 최근 경피적 심폐순환 보조장치는 여러 원인의 심인성 쇼크나 심정지의 치료에 매우 활발하게 적용되고 있다. 하지만 개심술 후 체외순환 이탈에 실패한 경우 적용하는 경피적 순환보조는 아직 예후가 매우 불량하다고 알려져 있다. 본 연구는 개심술 후 체외순환 이탈에 실패하여 경피적 심폐순환 보조장치를 적용한 환자들의 임상성적을 알아보고, 이들의 예후에 영향을 미치는 요인들에는 어떠한 것들이 있는지 알아 보고자 시행하였다. 대상 및 방법: 2005년 1월부터 2008년 12월까지 개심술 후 심폐기 이탈에 실패하여 경피적 순환 보조장치(CAPIOX emergent bypass system, $EBS^{(R)}$, Terumo Inc, Tokyo, Japan)를 적용한 10명의 환자들의 의무기록을 후향적으로 분석하였다. 결과: 평균 연령은 $60.2{\pm}16.5$세($19{\sim}77$세)였고, 평균 체외순환보조기간은 $48.7{\pm}64.7$시간($4{\sim}210$시간)이었다. 순환 보조 장치를 이탈할 수 있었던 경우는 6예(장치 이탈율 60%), 생존퇴원은 5예(생존율 50%)였다. 합병증은 5명(50%)에서 발생하였다. 단변량 분석에서 수술 중 대동맥 겸자시간이 길었던 경우, 순환 보조기간 중 종격동 출혈이 있었던 경우, 순환 보조장치 삽입전의 Troponin-I 수치가 높았던 경우가 사망에 영향을 미치는 인자로 조사되었다. 퇴원한 환자는 모두 생존하여 평균 $34{\pm}8.6$개월($23{\sim}48$개월)간 추적 관찰 중이다. 결론: 개심술 후 체외순환 이탈에 실패하게 되는 경우 매우 높은 사망률을 보이는 바 이들 환자에 대하여 적극적인 경피적 순환 보조장치의 적용으로 향상된 생존율을 기대할 수 있었다. 앞으로 지속적인 생존을 향상 및 합병증 감소를 위한 보다 많은 경험 및 임상연구가 필요할 것으로 생각된다.
