INTRODUCTION Splenic artery embolisation (SAE) has been shown to be an effective treatment for haemodynamically stable patients with high-grade blunt splenic injury. However, there are no local estimates of how much treatment costs. The purpose of this study was to evaluate the cost of providing SAE to patients in the setting of blunt abdominal trauma at an Australian level 1 trauma centre. METHODS This was a single-centre retrospective review of 10 patients who underwent splenic embolisation from December 2017 to December 2018 for the treatment of isolated blunt splenic injury, including cost of procedure and the entire admission. Costs included angiography costs including equipment, machine, staff, and post-procedural costs including pharmacy, general ward costs, orderlies, ward nursing, allied health, and further imaging. RESULTS During the study period, patients remained an inpatient for a mean of 4.8 days and the rate of splenic salvage was 100%. The mean total cost of splenic embolisation at our centre was AUD$10,523 and median cost AUD$9959.6 (range of $4826-$16,836). The use of a plug as embolic material was associated with increased cost than for coils. Overall cost of patients requiring ICU was mean AUD$11,894 and median AUD$11,435.8. Overall cost for those not requiring ICU was mean AUD$7325 and median AUD$8309.8. CONCLUSION Splenic embolisation is a low-cost procedure for management of blunt splenic injury. The cost to provide SAE at our centre was much lower than previously modelled data from overseas studies. From a cost perspective, the use of ICU for monitoring after the procedure significantly increased cost and necessity may be considered on a case-by-case basis. Further research is advised to directly compare the cost of SAE and splenectomy in an Australian setting.
