Calcification of the ascending thoracic aorta may make aortic cross-clamping dangerous and aorta-coronary artery bypass grafting impossible. A patient with a severely calcified ascending aorta owing to syphilitic aortitis presented such a problem. Sequential saphenous vein grafting was done to three coronary arteries, the proximal anastomosis being made to the noncalcified innominate artery. This technique may offer a practical solution to this problem.
胸段升主动脉钙化可能会使主动脉交叉钳夹术变得危险，且无法进行主动脉冠状动脉旁路移植术。一名因梅毒性主动脉炎导致胸段升主动脉严重钙化的患者就出现了这样的问题。对三条冠状动脉进行了序贯大隐静脉移植，近端吻合口位于未钙化的无名动脉。该技术可能为这一问题提供一个切实可行的解决方案。
