Smedberg C, et al. - In patients undergoing thoracic endovascular aortic repair (TEVAR), early and late outcomes for acute or subacute non-traumatic type B aortic dissection (TBAD) were analyzed, with the particular aims of identifying prognostic morphological predictors, and to assess the magnitude of the impact of the timing of TEVAR. Researchers analyzed a retrospective, two centre, population based consecutive case series. Findings revealed that all the early deaths demonstrated a false lumen area >50% of the total aortic cross-sectional area at the level of the tracheal bifurcation. The markedly worse outcome was noted for patients needing urgent TEVAR.
