Grafting with the internal mammary artery: correlation between preoperative angiography and intraoperative findings.
No data exist on the relation between angiography of the internal mammary artery and intraoperative findings during bypass surgery. We studied 47 consecutive patients and found no atherosclerotic changes. Intraoperatively, however, 4 left internal mammary arteries were judged unsuitable for grafting. No relation could be found to the diameter of the vessel as judged angiographically. Possible causes of unsuitability are discussed.
