title: Infected descending aortic fistula.
abstract: Two patients, each with an infected descending thoracic aortic fistula, are described. The first patient had a postpneumonitic empyema. Thoracostomy tube drainage resulted in obliteration of the empyema cavity. Upon slight withdrawal of the tube, 49 days after its insertion, massive pulsating bleeding occurred through the sinus tract. The bleeding was controlled with manual pressure at the entry site of the chest tube, and the patient was operated upon immediately. A descending aortic defect, 3 cm long X 1.5 cm wide, at the site of the thoracostomy tube was primarily closed. Ten months after the surgical procedure, the patient has had no difficulty referable to her aortic erosion. In the second patient, 9 months after removal of the T-10 vertebra (which had a large cell tumor) and replacement of the vertebra with Dunn's metallic device, hemoptysis and left lower lobe consolidation developed. Aortography demonstrated a lobulated false aneurysm, 4 cm wide X 6 cm long, at the site of Dunn's device. A 16-mm graft was sutured end to side to the descending aorta just distal to the left subclavian artery and to the abdominal aorta below the renal arteries. The false aneurysm was then removed, the two ends of the aorta were sutured, and the stumps were covered with omental graft. Nine months after the repair the patient has had no difficulty referable to the aortic surgery.
