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: Median follow-up time was 4.6 years (range, 1.9–7.8 years). The longest follow-up available in TEVAR group was 7.5 years. Loss to follow-up for long-term reintervention for the overall cohort was 22%. Sensitivity analysis for long-term reintervention among patients with incomplete follow-up demonstrated a 4.7% increase in possible reinterventions across the board in the most extreme case (all noncontacted patients assumed failed), but with minimal (<3.5% change) to the survival standard error (P=0.50). Intervention-free survival differed significantly between uncomplicated (84.8% and 62.7% at 1 and 5 years, respectively) and complicated (66.6% and 44.3% at 1 and 5 years, respectively) presentations (P<0.0001; Figure 2). Some variation among the treatment groups in the complicated subjects was evident, with TEVAR approaching a lower reintervention-free survival (P≈0.07; Tables 3 and 4).
