INTRODUCTION: Acute @entity1188 (ARI) is an uncommon disease, whose real incidence is probably higher than expected. It is associated with poor prognosis in a high percentage of cases. OBJECTIVES: To describe the main clinical, biochemical and radiologic features and to determine which factors are associated with poor prognosis ( @entity204 or permanent @entity8 ). MATERIALS AND METHODS: The following is a retrospective, observational, single-hospital-based study. All @entity1 diagnosed with ARI by contrast-enhanced computed tomography (CT) over an 18-year period were included. @entity1 were classified according to the cardiac or non-cardiac origin of their disease. Clinical, biochemical and radiologic features were analysed, and multiple logistic regression model was used to determine factors associated with poor prognosis. RESULTS: A total of 62 @entity1 were included, 30 of which had a cardiac origin. Other 32 @entity1 with non-cardiac ARI were younger, had less comorbidity, and were less frequently treated with oral anticoagulants. CT scans estimated mean injury extension at 35%, with no differences observed between groups. A total of 38% of @entity1 had an unfavourable outcome, and the main determinants were: Initial renal function (OR=0.949; IC  95% 0.918-0.980; p=0.002), and previous treatment with oral anticoagulants (OR=0.135; IC 95% 0.032-0.565; p=0.006). CONCLUSIONS: ARI is a rare pathology with non-specific symptoms, and it is not associated with @entity66 or @entity943 in more than half of cases. A substantial proportion of @entity1 have unfavourable outcomes, and the initial renal function is one of the main prognostic factors.
