BACKGROUND: Non-operative management (NOM) is the standard of care in hemodynamically stable @entity1 with blunt @entity130 after @entity130 . @entity1416 ( @entity1416 ) is reported to increase observation success rate. Studies demonstrating improved splenic salvage rates with @entity1416 primarily compared @entity1416 with historical controls. The aim of this study was to investigate whether @entity1416 improves success rate compared to observation alone in contemporaneous @entity1 with blunt @entity130 . METHODS: We included adult @entity1 with blunt @entity130 admitted to five Level 1 @entity130 Centers between January 2009 and December 2012 and selected for NOM. Successful treatment was defined as splenic salvage and no splenic re-intervention. We calculated propensity scores, expressing the probability of undergoing @entity1416 , using multivariable logistic regression and created five strata based on the quintiles of the propensity score distribution. A weighted relative risk (RR) was calculated across strata to express the chances of success with @entity1416 . RESULTS: Two hundred and six @entity1 were included in the study. Treatment was successful in 180 @entity1 : 134/146 (92  %) @entity1 treated with observation and 48/57 (84  %) @entity1 treated with @entity1416 . The weighted RR for success with @entity1416 was 1.17 (0.94-1.45); for complications, the weighted RR was 0.71 (0.41-1.22). The mean number of transfused blood products was 4.4 (SD 9.9) in the observation group versus 9.1 (SD 17.2) in the @entity1416 group. CONCLUSIONS: After correction for confounders with propensity score stratification technique, there was no significant difference between embolization and observation alone with regard to successful treatment in @entity1 with blunt @entity130 after @entity130 .
