Our experience with the internal mammary artery (IMA) for coronary bypass grafting in the past 3 years includes 323 grafts in 253 patients. After an initial group of IMA to left anterior descending (LAD) coronary artery grafts, we began using the IMA to bypass circumflex and small right coronary arteries (RCA). This report describes our experience with IMA bypass of coronary vessels other than the LAD. A total of 96 patients have had an IMA graft to the circumflex or RCA. Most of these patients had two or more bypasses. The mortality rate for this group has been 7 per cent, 7 of 96 patients. Postoperative angiography in 82 of 89 survivors has shown a patency rate of 98 per cent in 83 of 85 grafts studied. We conclude that the IMA is the vessel of choice for coronary artery bypass and that it can be used to bypass any of the main coronary arteries.
我们在过去3年中使用乳内动脉（IMA）进行冠状动脉旁路移植术的经验包括为253例患者进行了323次移植。在最初一组将IMA移植至左前降支（LAD）冠状动脉后，我们开始使用IMA来绕过回旋支和右冠状动脉小分支（RCA）。本报告描述了我们使用IMA绕过LAD以外冠状动脉血管的经验。共有96例患者接受了IMA移植至回旋支或RCA。这些患者中的大多数进行了两次或更多次旁路移植。该组的死亡率为7%，即96例患者中有7例死亡。89例幸存者中的82例术后血管造影显示，在研究的85根移植血管中的83根通畅率为98%。我们得出结论，IMA是冠状动脉旁路移植的首选血管，并且它可用于绕过任何主要冠状动脉。
