Outcomes of Patients With Acute Type B (DeBakey III) Aortic Dissection: A 13-Year, Single-Center Experience.
Bottom Line: Outcomes were compared between the groups by use of Kaplan-Meier and descriptive statistics.Overall survival was significantly related primarily to complicated presentation.Although uATBAD was associated with favorable early survival, late complications still occurred, mandating radiographic surveillance and open or endovascular interventions.

Mentions: The overall survival was significantly related to complicated presentation (P<0.0001; Figure 3). Overall survival between treatment groups by complicated status at 1, 5, and 10 years was 91%, 76.6%, and 66.7% among uATBAD-medical; 70.6%, 58%, and 48.5% among cATBAD-medical; 76.9%, 62.7%, and 48.2% among cATBAD-open; and 78.4% and 58.8% among cATBAD-TEVAR, respectively (log-rank P=0.003). The longest follow-up available for cATBAD-TEVAR group was 7.5 years. Most of the heterogeneity described by the log-rank P value in these stratified survival figures (Figures 2 and 3) arises from the influence of complicated presentation rather than from treatment per se as evidenced by the Cox-regression estimates in Tables 3 and 4.
