[Long-term results of total aortic arch replacement using selective cerebral perfusion]

From June 1994 to July 2001, 92 consecutive patients underwent total aortic arch replacement using hypothermic selective cerebral perfusion. Forty-four patients had nondissecting fusiform or saccular aneurysms (non-ruptured 34, ruptured 10), and 48 patients had dissection (acute 37, chronic 11). Hospital mortality rate was 6.8% in the nondissecting group and 6.3% in the dissecting group. No major operative cerebral complications were observed. There were 9 late deaths in the nondissecting group and 5 late deaths in the dissecting group. The actuarial survival rate was 61.6% after 100 months in the nondissecting group and 82.5% after 86 months in the dissecting group (p = 0.5128). In the postoperative aortic accidents, there were 2 cases of the descending aortic rupture and 2 cases of cholesterol crystal embolization in the nondissecting group and 3 cases of thoracoabdominal grafting, 2 cases of re-operation in the ascending aorta and 1 case of descending aortic rupture in the dissection group. The actuarial freedom from aortic accidents was 88% after 100 months in the nondissecting group and 80% after 86 months in the dissecting group (p = 0.6908). Our surgical outcome of total aortic arch replacement using hypothermic selective cerebral perfusion are satisfactory.
