Objective
Clinical outcomes in acute type B aortic dissection patients with partial thrombosis of the false lumen have not been clearly elucidated. The purpose of this study was to investigate long-term mortality and incidence of surgical treatment by focusing on the status of the false lumen including partial thrombosis.Methods
One hundred three patients (69 males, mean age 67聽卤 13聽years) with acute type B aortic dissection were enrolled. Patients were divided into three groups according to the status of the false lumen on enhanced computed tomography image (complete thrombosis, n聽= 55; partial thrombosis, n聽= 25; patent, n聽= 23).
Results
Requirement of surgical (open or endovascular) treatment during initial hospitalization was significantly less frequent in patients with complete thrombosis (0% in complete thrombosis, 16% in partial thrombosis, and 26% in patent). The long-term mortality (mean follow-up term, 1143聽卤 933聽days) did not differ among the three groups. Long-term surgical treatment-free rate was significantly lower in patients with patent false lumen. Cox regression analysis revealed that age (P聽< .01) and male sex (P聽= .013) were significant predictive factors of long-term mortality.
Conclusions
In acute type B aortic dissection, the incidence of surgical treatment was higher in patients with patent false lumen during long-term follow-up, whereas status of the false lumen did not influence long-term mortality.
