Simultaneous resection of the pulmonary lobe and descending thoracic aorta aneurysm is a rarely performed surgical procedure. As such, it is associated with increased risk of death and perioperative complications. In this study, the patient was subjected to excision of the left lower lobe and suturing of a dacron patch into the descending aorta without the use of cardiopulmonary bypass. The perioperative period proved uneventful. The patient was discharged from the hospital 10 days after the operation.
