Cost Utility of Splenic Artery Angioembolization for High-Grade Splenic Injury

Abstract Background: Management of blunt spleen injuries has evolved from mandatory splenectomy to non-operative man-agement (NOM) allowing for splenic salvage, Splenic artery embolization (SAE) has been shown to be an effective treat-ment for hemodynamically stable patients with high-grade blunt splenic injury. However, there are no local estimates of how much treatment costs. Aim of Study: The aim of this study was to evaluate the cost of providing SAE to patients in the setting of blunt abdominal trauma with splenic injury and to determine if the costs of an added, preventative procedure (SAE) early in management of blunt splenic injury would be offset by added utility by avoiding splenectomy. Patients and Methods: This study was a retrospective cohort study from a tertiary institution (50 patients in King Khaled Hospital Trauma Center, Hail, KSA and 9 patients in Al Hussein University Hospital, Cairo, Egypt). A total of 59 patients were treated with embolization in this period for blunt trauma, and however 39 cases were excluded given the presence of multiple concomitant injuries. Isolated splenic injury treated with SAE were identified in 20 patients and included for final analysis. Of these 10 patients, none required subsequent splenectomy following SAE. Results: The mean total angiography costs were 1837.94±  405.368 $, the costs of post-procedure management of patients including all hospital costs prior to discharge with associated length of stay. Conclusion: Splenic embolization is a low-cost procedure for management of blunt splenic injury. The cost to provide SAE at our center was much lower than previously modelled data from overseas studies. Further research is advised to directly compare the cost of SAE and splenectomy in other countries.
