A 72-year-old woman underwent replacement of the ascending aorta because of acute aortic dissection. During surgery, the right pulmonary artery was injured. Direct suture closure led to pulmonary artery stenosis with elevated central venous pressure and recurrent ventricular fibrillation. Extracorporeal membrane oxygenation stabilized her hemodynamic condition. She was weaned from the device 6 days later. Pulmonary angiography revealed severe obstruction of the right pulmonary artery but she had no respiratory symptoms thereafter.
