[A case of ruptured descending thoracic aortic aneurysm due to Salmonella infection]

Rupture of infectious aneurysm of the thoracic aorta into the lung after radical esophageal cancer surgery

A 60-year-old male underwent radical operation for esophageal cancer 45 days prior to complaining of several incidents of hemoptysis. The hemoptysis was found to be caused by infectious aneurysm of the descending thoracic aorta penetrating the lung. The aneurysm was resected and the aortic wall was sutured directly under percutaneous circulatory pulmonary support system. The sutured thoracic aorta was wrapped with the pedicle of an intercostal muscle flap to prevent reinfection. Forty-eight days after the aortic wall suture operation, however, the patient experienced massive hemoptysis and went into shock. Angiography was reveal no arterial lesions, so emergency left lower lobectomy was performed on suspicion of lung vessel rupture. Immediately after the lower lobectomy, recurrence of the aortic wall rupture caused uncontrollable bleeding. The patient died intraoperatively.
