During the 3 years through December 1992, 118 cases of coronary bypass graft were performed at Department of Cardiothoracic Surgery, Asan Medical Center. They consisted of 80 males and 38 females with the mean age of 59. History of myocardial infarction was noted in 23 cases[20%], congestive heart failure in 11[10%], left ventricular aneurysm in 6, postinfarct VSD in 2, and mitral regurgitation in 1. The angina was stable in 13 cases, and unstable in 104 cases[89%]. Left main stem disease were 41 cases[35%], triple vessel 36[31%], double vessel 30[26%] and single vessel involvement[LAD] in 10. We performed 335 distal bypasses out of 117 cases, with single bypass in 9, double 29, triple 52, quadruple 23, and quintuple 4. Myocardial protections were cardioplegia in 29 and intermittent aortic occlusion 79 and continuous aortic perfusion 7. The ischemic time per graft was 13 minutes[intermittent aortic occlusion group] and 20 minutes [cardioplegia group] respectively, and the mean number of graft per patient is 2.85. Early mortality was 6.8% [8/117]. If we exclude the patients with LV aneurysm, the surgical mortality could be downed to 4.5% [5/111]. The causes of deaths were cardiogenic shock[6], aortic dissection[1], and neurologic complication[1]. We conclude that noncardioplegic myocardial protection may be equally beneficial or sometimes advantageous to cardioplegic technique in aortocoronary bypass graft surgery.

Background: Early patency of the coronary artery bypass grafting is determined mainly by surgical technique and status of coronary artery. We analyzed the early result, focusing on the relationship between postoperative angiographic findings and the patency rate. Material and method: During the period of July 1997- August 1999, 86 cases of CABG were performed and the postoperative coronary artery angiography was done in 76 cases on postoperative day 7 to assess the graft patency. Result: Overall graft patency was 90.2% on the angiographic finding. Factors influencing the early graft occlusion were the surgeon's experience, small coronary artery size less than 1.5mm in diameter, coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site(p<0.001). Operative mortailty was 2.3%. Early recurrence of the symptom was 19.8% during the follow up period. Conclusion: We examined the postoperative coronary angiography and found that the surgeon's experience, small coronary artery size less than 1.5mm in diameter, bypass surgery on the coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site were the factors for the graft occlusion.

Between March, 1989, and August, 1993, 10 patients underwent aortocoronary bypass surgery concomittant with cardiac valve replacement. They were 6 men and 4 women, the age ranging from 47 to 64. 7 patients underwent single valve replacement and 2 patients underwent double valve replacement, Another one patient underwent only CABG one year after valve replacement and he had no evidence of prosthetic valve failure. Total number of graft vessels were.15,14 were saphenous venous grafts and 1 was internal mammary artery graft. Dyspnea on exertion was frequent symptom and was found in all patients. 8 patients presented stable angina, only 1 patient presented postinfarct angina and another 1 patient presented no angina symptom. The graft was placed prior to valve replacement and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout operation. Postoperative course was uneventful and there was no hospital mortality, as was supported by many reports, it is our opinion that simultaneous valve replacement and aortotomy bypass graft does not increase the risk of cardiac valve replacement substantially.

This study was to compare the functional status. complication and readmission rates. and client satisfaction with nursing care of home-based care and hospital-based care for clients with Coronary Artery Bypass Graft. Raw data were collected by interviewing and reviewing charts of 41 clients with Coronary Artery Bypass Graft between June 2001 and July 2002 at an university hospital located in Seoul. Korea. Out of 41 clients. 15 were in home care group and 26 were in hospitalization group. The baseline characteristics of the groups were almost identical. Mean age was 61.7 and 75.6% of clients being male. For home care group. the data collection was made at discharge and at termination of home care. and for hospitalization group. at discharge and at the first visit of outpatient department. Complication and readmission rates were investigated at one month after operation. Collected data were then analysed by conducting Chi-square test. Wilcoxon rank sum test. and Wilcoxon signed ranks test with SPSS program. The level of significance was .05. The results of the study are summarized as follows: 1. Postoperative length of stay of the home care group was shorter than that of hospitalization group by 1. 14 days(8.45 days vs. 9.59 days). On average. 1.8 home visits per client were observed. 2. The functional status (Barthel Index) at the termination of home care was significantly increased from that at discharge. For hospitalization group. a significant increase was observed between the functional status at the discharge and that at the first visit of outpatient department. The differencies in incremental of the scores. between the groups. were however not significant. 3. Complication and readmission rates; no statistically significant difference between the groups was observed. 4. The client satisfaction with nursing care (CSS) at termination of home care was significantly higher than that at hospital discharge. In conclusion. the outcomes of the analysis suggest that the home care benefits clients with Coronary Artery Bypass Graft. Client satisfaction with nursing care rises at termination of home care as compare to that measured at hospital discharge. Meanwhile. there was no significant differences in functional status. and complication and readmission rates. Further. home care reduced the length of stay in hospital.

Different suture techniques have been used for anastomosis in coronary artery bypass graft surgery. Bypass surgery may be difficult for patients who have small coronary arteries or marked size discrepancies between target coronary arteries and grafts. For proximal and distal anastomoses, three continuous stitches are first placed in the heel and toe of the small coronary arteries; for sequential anastomosis, an interrupted eight-stitch technique is used. We applied these anastomotic suture techniques in patients requiring coronary artery bypass graft surgery, achieving an early angiographic patency rate of 100%.

Objective : The aim of the study is to determine the efficacy of indocyanine green (ICG) videoangiography for confirmation of vascular anastomosis patency in both extracranial-intracranial and intracranial-intracranial bypasses. Methods : Intraoperative ICG videoangiography was used as a surgical adjunct for 56 bypasses in 47 patients to assay the patency of intracranial vascular anastomosis. These patients underwent a bypass for cerebral ischemia in 31 instances and as an adjunct to intracranial aneurysm surgery in 25. After completion of the bypass, ICG was administered to assess the patency of the graft. The findings on ICG videoangiography were then compared to intraoperative and/or postoperative imaging. Results : ICG provided an excellent visualization of all cerebral arteries and grafts at the time of surgery. Four grafts were determined to be suboptimal and were revised at the time of surgery. Findings on ICG videoangiography correlated with intraoperative and/or postoperative imaging. Conclusion : ICG videoangiography is rapid, effective, and reliable in determining the intraoperative patency of bypass grafts. It provides intraoperative information allowing revision to reduce the incidence of technical errors that may lead to early graft thrombosis.

1994년 7월부터 1995년 8월까지 서울대학교병원 흉부외과에서 시행한 관상동맥 우회술 78례 중 49례 (62,8%)에서 수술 1년 후 관상동맥 조영술을 시행하여 이식 혈관의 개존성을 조사하였으며, 수술 전,후 및 수술과 관련된 여러 위험 요소들이 개존성에 미치는 영향에 대하여 분석하였다. 관상동맥 우회술 후 평균 13.4$\pm$2.1개월 째에 관상동맥 조영술을 시행하였다. 내유동맥으로 문함을 시행한 60개소 중 3개소에서 string sign을 보였으나, 폐쇄 없이 전례에서 개존성이 유지되었으며, 요골동맥으로 문합을 시행한 4개소는 모두 개존성이 유지되었다. 복제정맥으로 문합을 시행한 81개소 중 69개소(85.2%)에서 개존성이 유지되었으며, 12개 소(14.8%)에서 폐쇄되었다. 개존성에 미치는 위험요소로 수술 전,수술 중 그리고 합병증 등의 수술 후 요소로 나누어 일원적 및 다원적으로 분석하였으며, 내유동맥의 협착 과 복재정맥의 개존성, 폐쇄에 미치는 요소들을 분석하였다. 내유동맥은 환자의 연령(60세 이상),수술 후 대동맥 내 풍선펌프의 삽입,수술 후 출혈, 및 급성신부전 등 합병증이 이식 혈관의 협착과 관련된 위험 인자였으며, 복제정맥은 우회술을 시\ulcorner 받은 관상동맥의 직경이 1.5mm 이하인 경우가 이식 혈관의 폐쇄 위험성과 관련된 위험 인자로 분석되었다(p<0.05). 관상동맥 우회술 1년 후 이식 혈관의 개존성은 내유동맥이 복재정맥보다 우수함을 보였으며 환자 연령 수술 후 대동맥 내 풍선펌프의 삽입여부, 출혈, 급성 신부전 등의 합병증 및 문합된 관상 동맥의 직경 등이 개존에 관련된 요소로 분석되었다. 이러한 결과를 토대로 수술 후 이식혈관의 폐쇄 여부에 대한 11측과 수술 방법이나 수술 후 환자의 추적 관찰에 도움을 줄 수 있으리라 생각된다.

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.
