Calcification of the ascending aorta may render aortic cross-clamping dangerous and aorta-coronary artery bypass grafting impossible. Coronary artery bypass grafting in a 72-year-old woman with drug resistant unstable angina and severely calcified ascending aorta owing to aortitis was successfully performed with aortic no touch technique which consisted of utilization of the left internal thoracic artery, fibrillatory arrest without aortic cross-clamping, left ventricular venting, and femoral artery perfusion. Her postoperative course was uneventful, and she is relieved of angina.
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搭桥术。对于一名72岁患有药物抵抗性不稳定型心绞痛且因大动脉炎导致升主动脉严重钙化的女性患者，采用了主动脉无接触技术成功进行了冠状动脉搭桥术，该技术包括使用左胸廓内动脉、在不进行主动脉交叉钳夹的情况下进行纤维颤动停搏、左心室排气以及股动脉灌注。她术后恢复顺利，心绞痛症状得到缓解。
