Treatment of abdominal aortic aneurysm (AAA) has changed over time, with endovascular repair (EVAR) being the main technical revolution. This study assessed the effect of this change on outcome on a national basis over a 17-year interval.
Primary infrarenal AAA repairs in Swedish residents aged 50 years and older, in the Swedish Vascular Registry (Swedvasc) 1994-2010, were analysed. The rate per 100,000 population, patient characteristics, operative technique and outcome were assessed for the intervals 1994-1999, 2000-2005 and 2006-2010.
Some 11,336 intact aneurysm repairs were performed. The overall rate per 100,000 increased (18.4 in 1994-1999, 19.4 in 2000-2005 and 24.0 in 2006-2010; P
