초록

최근 들어 관상동맥 질환과 관상동맥 우회술은 점차 증가하고 수술성적은 점차 나아지고 있다. 국립의료원에서도 1985년 관상동맥 우회술을 시작한 이래 154예의 수술을 시행하였으며, 이에 대한 성적을 분석, 보고하는 바이다. 대상 및 방법: 1985년 1월부터 2004년 6월까지 관상동맥 우회술을 받은 148명을 대상으로 154예의 수술을 시행하였으며, 수술 전 진단, 관상동맥 질환 정도, 시행한 수술의 종류, 이식된 혈관의 종류, 원위부 문합수, 동반된 술식, 수술 후 심기능 보조를 위한 대동맥내 풍선펌프의 이용 추이, 수술 후 합병증 및 사망률 등을 비교, 분석하였다. 결과: 148명에서 성비는 남녀 각 84명$(56.8\%)$, 64명$(43.2\%)$이었으며, 평균연령은 $58.9\pm8.3$세였다. 수술 전 진단은 불안전성 협심증 97예$(63.0\%)$, 안정성 협심증 31예$(20.1\%)$, 급성 심근경색이 12예$(7.8\%)$, 심근경색 후 협심증이 14예$(19.1\%)$이였다. 수술 전 관상동맥 조영상 좌주 관상동맥질환 12예$(7.8\%)$, 삼혈관 질환 68예$(44.2\%)$, 이 혈관 질환 39예$(25.3\%)$, 일혈관 질환 55예$(22.7\%)$이었다. 총 154예 중 체외순환하 관상동맥 우회술이 78예$(50.6\%)$, 비체외순환하 수술이 76예$(49.4\%)$였고, 3예에서 비체외순환하 관상동맥 우회술에서 체외순환하 관상동맥 우회술로의 전환이 있었다. 원위부 문합수는 총 319개, 평균 $2.06\pm0.96$이었다. 관상동맥 우회술시 다른 수술이 동반되었던 경우가 총 10예$(6.5\%)$였다. 수술 후 대동맥내 풍선펌프는 21예$(13.6\%)$에서 이용하였으나, 비체외순환하 수술에서는 4예$(5.1\%)$로 줄었으며, 전체 사망환자는 12명$(7.9\%)$이었으나, 2001년 이후에는 111예 중 5명$(4.5\%)$으로 감소하였다. 수술합병증으로 수술 전후의 심근경색증 9예$(5.8\%)$, 저심박출증 17예$(11\%)$, 부정맥 30예$(19.5\%)$등이었다. 결론: 국립의료원 흉부외과에서는 관상동맥 우회술을 시작한 이래 수술경험의 축적, 비체외순환하 관상동맥 우회술의 도입, 내흉동맥 및 요골동맥으로의 이식편 이용 변화에 따라 수술성적이 향상되었음을 알 수 있으며, 향후 더 많은 임상경험의 축적 및 장기 추적 관찰이 필요하다고 사료된다.

Recently, coronary artery obstructive disease and coronary artery bypass graft surgery have increased, and the operative result has been improved. We reviewed 154 cases of coronary artery bypass graft surgery from Jan. 1985 to Jun. 2004. Material and Method: We reviewed 148 patients, 154 cases of coronary artery bypass surgery from Jan. 1985 to Jun. 2004. This investigation is designed to illustrate the preoperative diagnosis, severity of disease, operative method, the kind of used bypass graft used, number of distal anasomosis, associated surgery, and postoperative morbidity and mortality. Result: There were 84 males, 64 females and the average age was $58.9\pm8.3$ years old. Preoperative clinical diagnosis were unstable angina in 97 cases $(63.0\%)$, stable angina in 31 cases $(20.1\%)$, acute myocardial infarction in 12 cases $(7.8\%)$ and postinfartion angina in 14 cases $(9.1\%)$. Preoperative angiographic diagnosis were three-vessel disease in 68 $(44.2\%)$, two-vessel disease in 39 $(25.3\%)$, one-vessel disease in 35$(22.7\%)$, and left main disease in 12$(7.8\%)$ cases. There were 78 cases of on-pump coronary artery bypass graft surgery and 76 cases of off-pump coronary artery bypass graft surgery. The total distal anastomoses number was 319, mean number of anastomoses was $2.06\pm0.96$. There were 10 concomitant procedures. Postoperative intra-aortic balloon pump was used in 21$(13.6\%)$ cases, but only 4 cases were used at off-pump coronary artery bypass surgery. Total early mortality was $7.8\%$. The mortality was decreased as $4.5\%$ from Jan. 2001 to Jun. 2004. Post operative complication was perioperative yocardial infarction in 9cases$(5.8\%)$, low cardiac output syndrome in 17 cases$(11\%)$, and arrhythmia in 30 cases$(19.5\%)$ cases. Conclusion: Since 1985, The result of coronary artery bypass graft surgery has been improved because of more refined technique, use of off-pump coronary artery bypass surgery, use of internal thoracic artery and radial artery as bypass graft. We should study the long-term follow up more for better operative results.
