Abstract

Between 2001 and 2006, 3 neonates that had multilevel left ventricular outflow tract obstruction and a ventricular septal defect underwent the Norwood-Rastelli procedure. The body weights ranged from 2.9 to 3.1 kg. The patients had a near normal sized mitral valve and left ventricle. We simultaneously performed a modified Norwood procedure with native tissues-to-tissue anastomosis without circulatory arrest, and a Rastelli type procedure using a non-valved conduit from the right ventricle to the pulmonary artery and intracardiac patch baffling from the left ventricle to the pulmonary valve via the ventricular septal defect. The postoperative courses were uneventful. During follow-up, there was one late mortality caused by a cardiac catheterization related complication at 7 months after surgery, One patient required a Rastelli conduit change. Two patients are doing well during a follow-up period of 1 and 5 years, respectively.

2001년부터 2006년까지 심실중격결손이 동반된 여러 부위의 좌심실유출로 협착 진단을 받은 3명의 신생아를 대상으로 하여 Norwood-Rastelli 술식을 시행하였다. 대상 신생아들의 체중은 $2.9{\sim}3.1 kg$ 이었으며 승모판막과 좌심실의 크기 및 형태는 정상이었다. 수술은 완전순환정지 없이 국소 관류하에서 자가 조직만을 이용하여 광범위하게 좌심실 유출로를 재건하는 수정된 Norwood 술식, 판막이 없는 우심막 도관을 이용하여 우심실과 폐동맥을 연결하는 Rastelli 형태의 술식 및 좌심실에서 폐동맥 판막으로 혈류가 가도록 연결하는 심실중격결손 폐쇄술을 시행하였다. 모두 수술 후 특별한 문제는 없었다. 추적 관찰 중 1명에서 수술 7개월 뒤 우심실유출로 도관의 협착으로 심도자술 도중 발생한 심정지와 이로 인한 합병증으로 사망하였다. 생존한 2명 중 1명은 우심실유출로 도관 협착으로 재수술을 받았으며 5년째 건강한 상태이며 나머지 환아도 1년째 건강한 상태로 외래 추적 중이다.
