Abstract

Background: The bidirectional cavopulmonary shunt (BCPS) is one of the primary palliative procedures for complex congenital heart disease. It has many advantages, but it is known to have high risks in young infants. Material and Method: From 1995 to 2003, 48 infants under the age of one year underwent BCPS. All the patients were Fontan candidates due to functional univentricular heart physiology. There were no significant differences in preoperative variables, except in mean age (67.58$\pm$3.78 vs. 212.91$\pm$13.44 days), and mean body weight (4.51$\pm$0.29 vs. 6.62$\pm$0.27 kg), between group A (<3 months, n=12) and group B ($\ge$3 months, n=36). Result: In group A, the arterial oxygen saturations serially measured were significantly lower. Hospital mortality was $25\%$, and $19\%$, respectively. During follow up, there were 2 late mortalities in group A, and 5 in group B. Conclusion: This study showed that operative risk in young infants was comparable to that of older patients, and BCPS could be a good option as a primary palliative procedure, and may eliminate other repeated palliative procedures which could be the risk factors for Fontan candidates. However, in high-risk patients accompanying pulmonary hypertension, or heterotaxia syndrome, other palliative procedures should be considered.

배경: 양방향성 상대정맥-폐동맥 단락술은 복잡심기형의 일차적 고식수술 중 하나로, 여러가지 장점이 있으나 유아 환아들에서는 수술 후 위험성이 높은 것으로 알려져 있다. 대상 및 방법: 1995년부터 2003년까지 48명의 1세 이하 환아들이 연세대학교 심장혈관병원에서 양방향성 상대정맥-폐동맥 단락술을 시행 받았다. 모든 환아들은 단심실로 인한 폰탄수술의 대상자였다. 환아들은 수술당시의 나이에 따라 두 군으로 분류되었다 A군(<3개월, 12명)과 B군(3${\~}$12개월, 36명) 간에 평균 나이(67.58$\pm$3.78 vs. 212.91 $\pm$ 13.44일)와 평균 몸무게(4.51 $\pm$0.29 vs. 6.62 $\pm$0.27 kg)를 제외한 술 전 변수들은 차이가 없었다. 결과: A군에서 연속적으로 측정한 동맥혈 산소 포화도가 통계학적으로 유의하게 낮게 나타났다. 병원 내 사망률은 각각 $25\%$$19\%$였다. 추적관찰 기간동안 A군에서 2명, B군에서 5명의 만기 사망이 있었다. 결론: 본 연구에서는 유아기의 환아들에서도, 수술 위험성이 나이가 든 환아들과 비교하여 비슷하여 양방향성 상대정맥-폐동맥 단락술이 후에 시행될 폰탄수술의 위험성을 높일 수 있는 반복적인 고식적 수술을 피할 수 있는 수술방법이라고 생각한다. 하지만, 폐동맥고혈압이나 Heterotaxia 증후군 등이 동반된 고위험군 환아에서는 다른 고식적 수술을 고려하는 것이 좋을 것으로 생각한다.
