Abstract

Increasing interest in the use of arterial conduits is based on the better patency of left internal thoracic artery (LITA) than that of saphenous vein (SV) graft and radial artery (RA) is emerging as one of them. We compared the early result of coronary artery bypass grafting (CABG) using UTA and RA (RA group) with CABG using UTA and SV only (SV group). Material and Method: We compared the early operative results of 45 cases in RA group with 45 cases in SV group selected from 165 cases who had CABG between January 2000 and December 2002. The two groups had similar profiles of age, sex, NYHA functional class, left ventricular ejection fraction and coronary angiographic anatomy. We analysed each group on the preoperative risk factors and operative results. Result: There were no statically signigicant difference between groups in operative mortality and each morbidities (stroke, IABP insertion, perioperative MI), respectively. However, the overall incidence of mortality and morbidities was lower in RA group compared to SV group (p < 0.05). RA group (2.93$\pm$0.62 days) had shorter duration of ICU stay than SV group (3.55$\pm$0.95 days) (p<0.001). The patency on postoperative coronary angiography at 7∼14 days after operation in RA group patients were 100% of LITA and RA and 94.9% of SV. Conclusion: We had better early operative results in RA group compared with SV group.

관상동맥우회술 시 내흉동맥의 장기개통률이 복재정맥의 경우보다 높은 것으로 보고되면서 동맥이식편에 대한 관심과 사용이 증가되고 있으며 그중의 하나로 요골동맥의 사용이 증가하고 있다. 이에 저자들은 좌내흉동맥과 요골동맥을 사용하여 시행한 관상동맥우회술의 성적을 좌내흉동맥과 복재정맥만을 사용한 경우와 비교하여 그 조기결과를 분석하였다. ,대상 뜻 방법: 2000년 1월부터 2002년 12월까지 시행한 관상동맥우회술 165예 중 요골동맥군 45예와 나이, 성별, NYHA, 좌심실박출계수, 수술 전 관상동맥조영술 소견이 유사한 복재정맥군을 수술 전 위험인자와 수술결과에 대해 비교분석하였다. 결과: 수술 사망률과 합병증(중풍, IABP삽입, 수술 중 심근경색) 각각의 발생률은 두군 간에 통계학적 차이가 없었으나 이들의 총발생률은 요골동맥군에서 복재정맥군보다 적었으며(p<0.05), 중환자실 재원기간은 요골동맥군이 2.93$\pm$0.62일로 복재정맥군의 3.55$\pm$0.95일에 비해 더 짧았다(p<0.001). 수술 후 7∼14일 사이에 요골동맥군에서 시행한 관상동맥조영술상 좌내흉동맥과 요골동맥의 개통률은 100%, 복재정맥은 94.9%였다. 걸론: 관상동맥우회술 시 내흉동맥과 요골동맥을 사용한 군에서 내흉동맥과 복재정맥만을 사용한 군보다 우수한 조기 수술 성적을 얻었다.
