[Late results of emergency operation in acute type A dissection].
77 cases of acute type A dissection underwent emergency operation during 5 years were studied. There were 37 men and 40 women, and 58 cases in type I, 19 cases in type II on DeBakey type. The grafting for the aorta including the tear was basically performed under selective brain perfusion and deep hypothermic circulatory arrest. The overall hospital mortality rate was 24.7%. However, it was 14% after using GRF glue. The overall actuarial survival rate for 58 patients who survived operation was 87% at 5 years after surgery. Late remnant false lumen-related complications were recognized in four patients (6.9%). For two of them, subsequent operations were performed. Another two patients died of rupture of remnant false lumen during observation. Aortic valve regurgitation was recognized preoperatively in 13 patients. None of them required subsequent operation in late phase. Results and countermeasure for late remnant false lumen-related and aortic valve-related complications were investigated.
