The length of aortic cross clamp time and the difficult control of bleeding sites can represent two major problems during the Ross operation. Dissection of the pulmonary root before aortic cross clamping as well as reconstruction of the right ventricular outflow tract only after completion of the aortic anastomosis and removal of the cross clamp appear to facilitate accurate hemostasis, reducing in addition the time of myocardial ischemia.
主动脉阻断时间长以及出血部位难以控制是Ross手术中的两个主要问题。在主动脉阻断前解剖肺动脉根部,以及仅在完成主动脉吻合和移除阻断钳后再重建右心室流出道,似乎有助于精确止血,此外还能减少心肌缺血时间。
