Abstract

Background: This paper reviews our experience retrospectively to examine the clinical results and effectiveness of lateral tunnel (LT) and extracardiac conduit (ECC) Fontan procedures at a single institution. Material and Method: One hundred and sixty five Fontan procedures were performed (67 LT and 98 ECC) between January 1996 and December 2006. Preoperative and postoperative hemodynamic values, arrhythmia, hospital and intensive care unit stay, chest tube drain, morbidity and mortality were reviewed. Result: The overall operative mortality in the LT and ECC groups was 4.5% (3) and 2.0% (2), respectively. There was a significant difference in the immediate postoperative transpulmonary gradient (LT $8.5{\pm}2.5$ vs ECC $6.6{\pm}2.4$, p-value<0.001) and central venous pressure (LT $18.3{\pm}3.8$ vs ECC $15.6{\pm}2.4$, p-value=0.001) between the two groups. The mean follow-up in the LT and ECC groups was $74.1{\pm}31.5$ and $38.1{\pm}29.1$ months, respectively. There was one late death. The actuarial survival at 10 years in the LT and ECC groups was 92% and 89%, respectively. In arrhythmia, the ECC patients showed a slightly low incidence but the difference was not statistically significant. Conclusion: Both the LT and ECC Fontan procedures showed comparable early and mid-term outcomes in terms of the surgical morbidity and mortality, postoperative hemodynamics, and mid-term survival. The ECC Fontan procedure reduces the risk of arrhythmia in the follow up period.

배경: 저자들은 저자들의 센터에서 일정 기간 동안 시행한 폰탄 술식의 중장기 성적을 알아보고자 하였으며, 특히 심장외 도관을 사용한 폰탄 술식과 가측 터널 폰탄 술식의 성적을 비교하고자 하였다. 대상 및 방법: 1996년 1월부터 2006년 12월에 걸쳐 67명의 가측 터널 폰탄 술식, 98명의 심장외 도관 폰탄 술식을 시행하였다. 환자들의 나이, 성별, 체중, 수술 전 심도자 검사 결과, 방실 판막의 역류 정도, 술전 부정맥의 여부 등에 대하여 조사하였으며 수술 후 성적에 대해서 조사 분석하였다. 결과: 수술 사망률은 가측 터널 폰탄 술식에서 4.5%, 심장외 도관 폰탄 술식에서 2.0%를 보였다. 수술 직후의 혈역학적인 측면에서 경폐압력차이와 중심정맥압은 심장외 도관 폰탄 술식에서 통계학적으로 의미있게 낮게 측정되었으나, 병원 재원 기간, 중환자실 체류 기간, 흉관 삽관 일수 등은 양 술식에 따른 의미있는 차이를 보이지 않았다. 추적 관찰 기간은 가측 터널 폰탄 술식 환자는 74.1개월, 심장외 도관 폰탄 술식 환자는 38.1개월이었으며, 기간 중에 1명의 만기 사망이 있었다. 10년간의 생존율은 가측 터널 폰탄 술식 환자에서 92%, 심장외 도관 폰탄 술식 환자에서 89%를 보였으며, 추적관찰 기간중의 부정맥 발생의 측면에서 살펴볼 때, 심장외 도관 폰탄 술식 환자에서 다소 낮은 발생률을 보였다. 결론: 폰탄 술식은 과거 10여 년 동안 비교적 만족할 만한 수술 성적을 보이고 있으며, 특히 심장외 도관 폰탄 술식을 사용하는 경우 부정맥의 발병이 비교적 낮았다. 이에 대해서는 보다 장기적인 추적관찰이 필요할 것이다.
