Of the 83 patients with acute type A aortic dissection, 47 received surgery during acute stage, 10 received it in the chronic stage, and 26 received nonsurgical therapy.
Of the 77 patients with acute type B aortic dissection, 27 received surgery during acute stage, 22 received it in the chronic stage, and 28 received nonsurgical therapy.
Ten-year survival rates for patients receiving surgery during the acute stage were 62% for type A and 64% for type B dissection. This survival rate for type A patients was significantly higher than that for type A patients not receiving surgery, but the corresponding difference for type B patients was not significant.
Present data indicate that immediate surgical intervention is indicated in patients with acute type A dissection, and elective operation in the subacute stage in patient with uncomplicated type B dissection following medical therapy in the acute stage.
