Abstract
We reviewed 24 cases of patchplasty for true thoracic aortic aneurysm performed in our hospital up to July 2001. The size of the aneurysm in the ascending aorta was 6.0cm (1 case), and the mean size in the aortic arch was 2.5±0.5cm (4 cases), that in the distal arch was 4.7±1.7cm (11 cases), and that in the descending aorta was 3.7±0.5cm (8 cases). The hospital mortality rate was 12.5% (3 patients out of 24). The causes of death were multiple organ failure, cerebral bleeding and sepsis. In the long-term results, 2 patients had recurrence, but there were no late deaths in relation to the aneurysmal recurrence. We performed open stent operations for severe adhesion and pulmonary dysfunction in the aneurysmal recurrence cases. The postoperative course of these cases was uneventful. The open stent was useful for the treatment of the aneurysmal recurrence in the distal arch.
