The impact of splenic artery embolization on the management of splenic trauma: an 8-year review

BACKGROUND: Splenic artery embolization (SAE) is an adjunct to nonoperative management (NOM) of splenic injuries. We reviewed our experience with SAE to identify its impact on splenic operations. METHODS: Patients admitted with splenic injuries over an 8-year period were identified and the initial method of management noted (simple observation, SAE, or splenic surgery). The first 4 years (period 1) during which SAE was introduced was compared with the latter 4 years (period 2) when it was used frequently. RESULTS: There were 304 patients in period I and 416 in period 2. NOM was initial management in 59.9% in period 1% and 60.1% in period 2 (P = 1.0) and failure rates were 5.3% versus 2.9%, respectively (P = .12). More SAE procedures were performed in period 2-13.7% versus 4.9% (P <= .001)-and there was a reduction in the proportion of splenic operations-35.2% versus 26.2% (P <.01). CONCLUSIONS: SAE is associated with a reduction in splenic operations, although it did not alter the failure rate of NOM. (C) 2009 Published by Elsevier Inc.
