[Postoperative follow-up of acute aortic dissection and the result of second operations].
Between January 1990 and March 1998, surgical treatment was performed in 75 patients with acute aortic dissection at Omiya Medical Center. Seventy-three patients (97%) of them were classified type A aortic dissection. Thirteen of them died due to hemorrhage (5 cases), cardiac failure (3 cases), visceral ischemia (3 cases) and others (2 cases) after the operation. Hospital mortality rate was 17.3%. Sixty-two survivors were followed up to 8 years. During the follow up period, five patients died due to pneumonia, gastric cancer, cardiac failure, brain hemorrhage and unknown event. Five-year survival rate including hospital death was 77% evaluated by Kaplan-Meier method. Second operations for the enlargement of residual false lumen with the entry were performed in 4 patients (6.5%) of 62 survivors. Second operations were also performed in other 6 patients referred to us from other hospitals because of the enlargement of false lumen. Nine of them survived (90%) and returned to their daily life.
