近年来，乳内动脉在冠状动脉血运重建中的应用已经扩大。在250例连续冠状动脉血运重建术中，222例患者（89%）至少有1例乳房内冠状动脉吻合术，77例患者（31%）进行了多次乳房内冠状动脉吻合术。在血运重建手术期间，4例患有内乳冠状动脉闭塞的患者无法脱离体外循环。这4例患者出现左心室衰竭体征，并对左前降支冠状动脉（已通过左乳内动脉进行血运重建）进行了额外的隐静脉旁路术。4例患者中有3例可以脱离体外循环。因此，在一些患者（1.2%）中，内乳冠状动脉闭塞为心肌提供的营养支持不足。
The use of the internal mammary artery for revascularization of the coronary arteries has expanded over the last years. In a series of 250 consecutive coronary artery revascularizations, there was at least 1 internal mammary-coronary artery anastomosis in 222 patients (89%) and multiple internal mammary-coronary artery anastomoses were performed in 77 patients (31%). During the revascularization procedure, weaning from cardiopulmonary bypass was not possible in 4 patients with internal mammary-coronary artery anastomoses. These 4 patients showed signs of left ventricular failure, and additional saphenous vein bypass to the left anterior descending coronary artery, already revascularized by the left internal mammary artery, was performed. Weaning from cardiopulmonary bypass was then possible in 3 out of 4 patients. Thus, in some patients (1.2%), internal mammary-coronary artery anastomoses provide inadequate nutritional support for the myocardium.
