Abstract

Background: It has been known that internal thoracic artery grafting has a better patency rate compare to other graft conduits in coronary revascularization. Better patency rates can be expected in more coronary arteries with the use of bilateral internal thoracic artery. However, there were some debates on the complications after the use of bilateral internal thoracic artery. The purpose of our study was to reveal the results of bilateral internal thoracic artery. Material and Method: The 26 coronary artery bypass operations with bilateral internal thoracic artery were performed from July 2001 to May 2002. We compared the results of 8 diabetic patients to those of 18 non-diabetic patients. We compared the results of BITA (bilateral internal thoracic artery) group to those of SITA (single internal thoracic artery) group that were 20 patients and performed during same period. Result: There was no mortality. There was one wound complication in the diabetic group and one in the non-diabetic group. There were no significant differences in operation time, duration of mechanical ventilation, amount of bleeding, infusing duration of cardiotonics, and complication between two groups. There were no significant differences in results between the BITA group and the SITA group. Conclusion: There were no significant differences in early results between the BITA group and the SITA group, and there were no significant differences in results between the diabetic group and the non-diabetic group. We think coronary artery bypass grafting with the use of bilateral internal thoracic artery is considered in diabetic patients.

배경: 관상동맥우회술 시 이용하는 내흉동맥은 그 장기 개통률이 다른 도판보다 우수하다고 알려져 있다. 또한 양측 내흉동맥을 이용하면 좋은 개통률로 보다 많은 관상동맥에 접근할 수 있다. 그러나 양측 내흥동맥의 박리로 수술조기 합병증이 증가할 것이라는 관점이 있어 보고자가 경험한 수술 조기결과를 보고하고자 한다. 대상 및 방법: 2001년 7월부터 2002년 5월까지 양측 내흉동맥을 이용하여 관상동맥우회술을 시행한 26예를 대상으로 하였다. 대상환자 중 당뇨병을 가진 8예와 당뇨병이 없는 18예를 비교하여 수술결과를 분석하였다. 또한 같은 기간에 단측 내흉맥을 이용하여 수술한 20예를 대상 환자군과 비교하여 그 수술결과를 분석하였다. 결과: 수술사망은 없었다. 수술 후 합병증은 창상감염으로 당뇨군과 정상군 각각 1예가 있었다. 당뇨군과 정상군 간에는 수술시간, 기관삽관시간, 출혈량, 강심제투여시간, 그리고 합병증 발생에서는 서로 차이가 없었다. 단측 내흉동맥군과 수술결과에 있어 차이가 없었다. 결론: 양측 내흉동맥을 이용한 관상동맥우회술의 수술 조기결과는 단측 내흉동맥을 이용한 수술결과와 차이가 없었고 양측 내흉동맥을 이용한 환자 중 당뇨병이 있는 경우에도 정상군과 수술결과의 차이는 없었다. 당뇨병 환자에 있어 양측 내흉동맥의 이용은 고려할 만하다고 생각한다.
