Abstract

An adequate location of the reimplanted coronary arteries is one of the most important prognostic factors for an arterial switch operation for treating TGA (transposition of great arteries). We report here on a case of malposition of the reimplanted coronary artery in a 14-year-old boy who had undergone an arterial switch operation. He had chest pain and dyspnea on exertion. The imaging study showed that the ostium of the left main coronary artery, which was between the neo-pulmonary artery and the neo-aorta, was compressed by the great arteries. We excised the left main coronary artery with a button incision from the aorta and reimplanted it on the left lateral side of the aorta. The patency of the left main coronary artery os after the operation was good and it was not compressed by the surrounding arteries.

대혈관전위 환자에서 동맥치환술 시행 시 관상동맥의 위치는 수술의 성적 및 환자의 예후에 매우 중요한 요소이다. 본 증례는 과거 대혈관전위로 동맥치환술을 시행 받았던 환자에서 발생한 관상동맥 압박에 대한 보고이다. 14세 남자 환자로 운동 시 협심증을 주소로 내원하였고, 영상학적 검사 결과 좌관상동맥 기시부가 대동맥과 폐동맥 사이에 위치하여 눌리고 있는 양상이어서 수술적 치료를 결정하였다. 수술은 좌관상동맥 기시부를 대동맥에서 버튼 절제한 후 좌외측으로 재이식하여 폐동맥에 눌리지 않도록 하였다. 수술 후 관상동맥의 대혈관에 의한 압박 소견은 사라졌으며 환자는 현재까지 합병증이나 증상 재발 없이 추적 관찰 중이다.
