Abstract

To understand the clinical results of aortic root replacement with either inclusion or open technique, we analysed 53 patients who underwent replacement of the aortic root with composite graft between October,1980, and May, 1995. Annuloaortic ectasia was the most common indication for operation(29 patients), follwed by aortic dissection(22 patients). Among 53 patients, 19(35%) had Marfan syndrome. Three patients died during hospitalization (Mortality: 5.5%). The follow up was possible in 48 patients(Follow-up rate; 94%,mean duration;37 months). The actuarial survival rate at 24 months was 95% in open technique group, and 87% in inclusion technique group. Late complications developed in 10 patients. Dissecting aneurysm in the remaining aorta was noted in 3 patients with inclusion technique, and a pseudoaneurysm from coronary artery anastomosis site developed in a patient with inclusion technique. In conclusion, there was no statistical differences in survival for 24 months between inclusion technique and open technique group. But late problems in the remaining aorta or death from unknown cause occurred with moderate frequency ; careful follow-up after aortic root replacement thought to be important for long term survival.
