BackgroundThe incidence of abdominal aortic aneurysms (AAAs) and their rupture has been reported to be decreasing. The aim was to evaluate trends in ruptured AAA (rAAA) incidence in the hospital district of Helsinki and Uusimaa (HUS) in southern Finland. This was a population-based retrospective review of all patients with rAAA in this well defined geographical area during 2003-2013.MethodsData for all patients treated for rAAA at Helsinki University Hospital, the only vascular surgery centre in an area of 1·5 million inhabitants, were collected from local vascular registry. All deaths attributed to rAAA were obtained from the cause of death registry of Statistics Finland.ResultsThe mean(s.d.) age of the 712 patients with rAAA was 76·5(9·6) years; 76·7 per cent of them were men. Only 330 patients (46·3 per cent of those with rAAA) arrived alive at Helsinki University Hospital. The turn-down rate for surgical treatment was 10·3 per cent. Of the 296 patients operated on, 199 (67·2 per cent) were alive at 30 days. Only 27·9 per cent of all patients were alive 30 days after rupture of the AAA. The incidence of rAAA was 4·3 per 100 000 inhabitants and the mortality rate was 3·2 per 100 000 inhabitants. A decreasing trend was seen in incidence and mortality during the 11-year study interval.ConclusionThe incidence of rAAA is decreasing in the HUS district. Mortality from rAAA remains very high, because half of the patients die before reaching the hospital.© 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.
