A 75-year-old woman required re-coronary artery bypass grafting due to flow insufficiency of the right internal thoracic artery (RITA). After the first operation, coronary angiography revealed a narrowed RITA. Myocardial ischemia occurred when the native coronary artery was occluded by the catheter. A stringlike internal thoracic artery is probably unable to increase blood supply immediately in response to the demand created by acute obstruction of the recipient native coronary artery.
一名75岁女性因右胸廓内动脉（RITA）血流不足需要再次进行冠状动脉搭桥手术。首次手术后，冠状动脉造影显示RITA狭窄。当导管阻塞自身冠状动脉时发生了心肌缺血。条索状的胸廓内动脉可能无法立即根据受者自身冠状动脉急性阻塞所产生的需求增加血液供应。
