Surgical Strategy for Thoracic Aortic Pseudoaneurysm with Sternal Adherence

抄録

A thoracic aortic pseudoaneurysm is a life-threatening complication following thoracic aortic surgery. We describe a surgical strategy for this pseudoaneurysm with a high risk for rupture during median sternotomy. The pseudoaneurysm was distended and widely adherent to the posterior sternum. Elective cardiopulmonary bypass and moderate hypothermia were established, and sternotomy was performed without left ventricle distention or brain ischemia. Total arch replacement was successful and the patient was discharged on post operative day (POD) 18. A key surgical strategy was to avoid ventricular fibrillation before sternotomy. Appropriate sternotomy timing and perfusion strategy are crucial for successful treatment.
