Operation for Type A Aortic Dissection with a Sutureless Ringed Intraluminal Graft

Abstract

Between 1984 and 1994, 58 patients underwent operations for type A aortic dissection. A sutureless ringed intraluminal graft was used in 9 of the 58 cases. The patients ranged from 47 to 74 years old (mean, 60.4 years). Six patients were discharged from the hospital and three patients died. The operative mortality rate for the 9 patients was 33.3% and for the other 49 patients it was 20.4%. Post-operative aortograms revealed a remaining false lumen in 5 of the 6 discharged patients. The result of the operation with the sutureless ringed intraluminal graft was not satisfactory. Therefore, we prefer to resect and replace the dissected aorta using the prosthetic graft rather than repair with the sutureless ringed intraluminal graft.
