초록

배경: 최근의 약물 용출 스텐트의 발전으로 급성 관동맥 증후군의 치료에 있어서 외과의 영역이 축소되어 가고 있다. 이에 저자들은 급성 관동맥 증후군 환자들의 수술적 치료에 대한 결과를 알아보고자 하였다. 대상 및 방법: 2001년 1월부터 2005년 8월까지 416명의 환자가 수술 전 ST분절의 상승을 동반하지 않은 급성 관동맥 증후군으로 진단되어 관상동맥 우회로 조성술을 시행 받았다. 평균 연령은 $61.8{\pm}9.0$세였고 남자가 276명(66.3%), 여자가 140명(33.7%)이었다. 심장혈관 조영술에서 삼혈관 질환이 324예(77.9%)였고 좌주 관상동맥 질환은 92예(22.1%)였다. 관상동맥 질환의 위험 인자로는 고혈압이 236예(56.7%), 당뇨가 174예(41.8%)에서 있었다. 종래의 심폐기하 관상동맥 우회로 조성술은 194예 (46.6%), 무인공심폐기하 관상동맥 우회로 조성술은 222예(53.4%)에서 시행되었다. 사용된 도관은 좌내흉동맥이 396예(95.2%), 우내흉동맥 85예(20.4%), 요골동맥 278예(66.8%), 복재정맥 316예(76.0%) 등으로 대동맥 조작 없이 동맥 도관만을 사용한 경우는 97예(23.3%)였다. 총 원위부 문합 수는 1,306개였고 환자 한 명당 평균 원위부 문합수는 $3.21{\pm}1.71$개였다. 결과: 수술 사망은 4예(1.0%), 수술 후 합병증은 65예(15.6%)에서 발생하였다. 152예에서 관상동맥 우회로 조성술 후 1개월에서 36개월 사이에 다중검출 전산화 단층촬영기(multi-directional computed tomography)로 각 이식편의 개존율을 추적 관찰 결과, 좌내흉동맥 95.3%(141/148), 우내흉동맥 98.1% (51/52), 요골동맥 92.2% (106/115), 복재정맥 89.0% (89/100)등의 개존율을 보였다. 결론: 급성 관동맥 증후군의 수술적 치료는 비교적 낮은 수술사망률과 우수한 이식편의 개존율을 보여주었다. 향후 약물 용출 스텐트를 이용한 내과적 치료와 장기 성적에 대한 비교 연구가 필요하다.

Background: Surgical role for acute coronary syndrome has been reduced in recent years due to development of drug eluting stent. We evaluated the surgical results of acute coronary syndrome in our hospital. Material and Method: Between January 2001 and August 2005, 416 patients underwent coronary artery bypass grafting (CABG) under diagnosis of non-ST-elevation acute coronary syndrome (NSTE ACS). Mean age was $61.8{\pm}9.0$ years and 276 (66.3%) patients were male. 324 (77.9%) patients had triple vessel disease and 92 (22.1%) had left main disease at angiographic study. 236 (56.7%) patients had hypertension and 174 (41.8%) had diabetes mellitus. Conventional on-pump CABG was performed in 194 patients (46.6%) and off-pump CABG in 222 (53.4%). Total arterial revascularization with no touch technique was done in 97 patients (23.3%). The number of total distal anastomosis was 1,306 and the number per patient was $3.21{\pm}1.71$. Result: Surgical mortality rate was 1.0% (4 patients) and postoperative complication rate was 15.6% (65 patients). Graft patency was checked at mean $3.7{\pm}7.6$ months (from 1 to 37 months) postoperatively with multi-directional computed tomography in 152 patients. Left internal mammary artery was patent in 95.3%, right internal mammary artery in 98.1%, radial artery in 92.2% and saphenous vein in 89.0%. Conclusion: The surgical treatment of NSTE ACS showed relatively low mortality rate and good graft patency rate. Further study is needed to compare the long term results with drug eluting stent.
