[Anesthetic management in a patient with acute dissection of the ascending aorta with difficult weaning from cardiopulmonary bypass due to acute myocardial infarction].

We report a case of acute dissection of the ascending aorta with difficult weaning from cardiopulmonary bypass (CPB) due to acute myocardial infarction (MI). Difficult separation from CPB was thought to be due to global coronary artery malperfusion, caused by diffuse left coronary artery sclerosis and the obstructed origin of the right coronary artery arising from the left sinus of Valsalva, resulting in intraoperative MI. In this case, supplemental coronary artery bypass grafting was effective for the separation of the patient from CPB.
