English abstract<\/strong><\/p>\n

Injuries involving major arteries and the thorax are major causes of mortality and morbidity worldwide. As studies on the epidemiology of vascular trauma are scarce, it is vital to better understand factors that predict mortality in trauma patients who reach hospitals alive. The aim of this doctoral thesis was to evaluate outcomes and prognostic factors associated with 30-day and long-term survival in this patient group in two well-defined Nordic patient cohorts in Iceland and Bergen in West Norway.<\/p>\n

The thesis consists of five scientific articles that included patients with major vascular injuries in traffic accidents in Iceland in the years 2000-2011, individuals who underwent emergency thoracotomy for cardiovascular trauma in the years 2005-2010 together with patients that were hospitalized for stabbing injury in 2000-2015 in Iceland. Furthermore, all patients that were admitted with vascular or thoracic injuries to Haukeland University Hospital in Bergen, from 2009\u20132018 were studied.<\/p>\n

The studies show that serious vascular injury is not a common cause of death in both Iceland and Western Norway. In both regions, they were most often caused by traffic accidents, in contrast to the US and UK where gunshot and knife injuries are a more common cause of vascular trauma. The 30-day mortality rate of patients is high after aortic injuries, particularly those that occur in rural areas. For the period 2000-2015, the incidence of serious stab injuries requiring hospitalization remained relatively stable in Iceland. \u00a0Emergency thoracotomy is a rarely performed procedure in Iceland; however, with a survival rate that is non-inferior to that reported in other Nordic countries. In-hospital mortality following severe vascular trauma was shown to be higher among females and patients with underlying comorbidities and those who suffered in-hospital complications. In Iceland and Norway, transport of trauma patients is often difficult for geographical reasons and weather, and although most trauma centres in these countries have low patient volumes, outcomes are in line to larger tertiary care trauma centres in N-Europe and N-America.<\/p>\n
