Splenic artery embolization improves outcomes and decreases the length of stay in hemodynamically stable blunt splenic injuries – A level 1 Australian Trauma centre experience

•A 13-year retrospective cohort study of hemodynamincally stable adult blunt splenic injury (BSI) patients from a level 1 trauma centre in Adelaide, South Australia, Australia.•208 out of 365 patients met the inclusion criteria, with 26% undergoing splenic artery angioembolisation (ASE) within 24 h and 45% non-operative management (NOM) only.•There was no difference in the overall success rates for each modality of primary management, though patients managed with ASE were older with higher grade of splenic injury and increased rates of haemo-peritoneum and contrast blush.•Grade III splenic injury patients managed with ASE had no failures compared to the NOM group with a significant reduction in length of hospital stay (LOS).•Overall, the ASE group had a significantly shorter LOS than the NOM group (10.0 vs 16.0 days, p
