Reutersberg B, et al. - Researchers analyzed hospital incidence and mortality for surgically/interventionally treated aortic dissections [ADs, including type A ADs (TAADs) and type B ADs (TBADs)] in Germany between 2006 and 2014, via this secondary data analysis of the nationwide diagnosis-related group statistics, compiled by the German Federal Statistical Office. This is the first nationwide report on this topic. For surgically/interventionally treated AD, the standardized hospital incidence was 2.7/100 000 per year, including 2.0/100 000 per year for TAAD and 0.7/100 000 per year for TBAD. For TAAD and TBAD, the respective estimated in-hospital mortality was 19.5% and 9.3%. An over time increase in hospital incidence and mortality of TAAD and TBAD was reported. It was safer to perform TAAD in high-volume centers. A significant association of age and comorbidity with a higher mortality risk was reported for TAAD in a multilevel multivariable analysis.
