From January 1991 to January 1995, 11 patients with aortic diseases underwent various surgical repairs. The age at operation ranged from 26 years to 63 years[ mean=50.9 years . The disease entities included 8 aortic dissections[ type I in 4, type II in 2 and type III in 2 cases , 2 Marfan`s syndrome with annuloaortic ectasia and 1 desecending thoracic aortic aneurysm The operative procedures we tried were 3 Bentall`s operation, 5 graft replacement of ascending aorta, and 3 graft interposition in descending thoracic aorta.Overall hospital mortality rate is 36.3%[4/11 . And causes of death are pump weaning failure in 2 cases and multiorgan failure in 2 cases. It was that 2 sternal dehiscence & mediastinitis, 1 acute renal failure, 2 hypoxic brain damages and 2 postoperative psychosis were complicated. Recently we tried surgical repair of aortic dissection five out of 6 cases using total circulatory arrest with deep hypothermia at 14$^{\circ}C$. Total circulatory arrest time ranged from 18 to 26 minutes[ mean 22.2 minutes , and mean aortic cross-clamping time was 48.2 minutes. One of 5 patient died on the 7th postoperative day due to multiorgan failure. Mortality of patients with TCA was 20%[1/5 , and it of remainders was 50%[3/6 . Our result for surgical repair using total circulatory arrest with deep hypothermia is satisfactory on the basis of our clinical data.
