[A successful surgical treatment of impending rupture of the thoracoabdominal aneurysm in the aged].

In a case with impending rupture of the thoracoabdominal aneurysm of a 78-year-old aged who was admitted to our hospital as chief complaints of dysphagia, sense of pressure in the thoracic region and bloody sputum, resection of the aneurysm and patch graft aortoplasty were carried out with the aid of partial cardiopulmonary bypass. The maximum diameter of the aneurysm was 12 cm, and adhered partially with lung, and a very thin ejected region of the wall was noted. Enlargement of the saccular aneurysm in the false lumen of the dissecting aortic aneurysm accompanying with massive mural thrombus was noted. The patch graft aortoplasty was performed because back bleeding from four sets of intercostal arteries (Th 9-Th 12) was remarkably noted. The postoperative course was uncomplicated, and dysphagia was disappeared without paraplegia. This case is considered to be the oldest one who was undergone the the thoracoabdominal aneurysm in our country.
