Abstract

Intracavitary coronary artery is variant anomalous entrance to right ventricular cavity of left anterior descending artery. Since the disease is extremely rare, there has not been any report of it in Korea and is only found in $0.2\~0.3\%$ of all CABG patients. It is very difficult to be diagnosed by preoperative coronary arteriography (CAG) and secure suture is needed for right ventriculotomy after CABG due to bleeding from right ventricle. Horizontal mattress suture with pledget has been recommended but, it could compress the myocardium surrounding ventriculotomy and result in disturbed flow of left anterior descending artery branch and perforating artery. So we used simple interrupted suture and the patient was recovered as other CABG patients without complications.

심강내관상동맥은 전체 관상동맥우회술 환자 중 약 $0.2\~0.3\%$에서 발견되며, 국내에서는 아직 보고된 바 없는 극히 드문 관상동맥기형의 일종이다. 수술 전 관상동맥조영술을 통하여 진단하기 어렵고, 관상동맥우회술 후에 우심실로부터의 출혈이 발생할 수 있으므로 우심실절개 부위의 견고한 봉합이 필요하다. 기존의 증례 보고에 따르면 외과용거즈(pledget)를 이용한 수평매트리스봉합(horizontal mattress suture)이 추천되기는 하나 주위의 심근을 압박하여 관상동맥가지 및 관통동맥의 협착을 유발할 수 있어, 단순단속봉합(simple interrupted suture)을 이용하고도 수술 후 별다른 합병증 얼이 호전된 예를 경험하였기에 보고하는 바이다.
