Pediatric splenic injuries with a contrast blush: successful nonoperative management without angiography and embolization

Abstract

Background The presence of a contrast blush on computed tomography (CT) in adult splenic trauma is a risk factor for failure of nonoperative management. Arterial embolization is believed to reduce this failure rate. The significance of a blush in pediatric trauma is unknown. The authors evaluated the outcome of children with blunt splenic trauma and contrast extravasation. Methods The trauma registry was queried for all pediatric patients with blunt splenic injuries. Admission CT was reviewed for injury grade and presence of an arterial blush by a radiologist blinded to patient outcome. Hospital and office charts were reviewed for success of nonoperative management, late splenic rupture, and other complications. Results One hundred seven children with blunt splenic trauma were identified over a 6-year period. Mean injury grade was 2.9. Six patients required emergency splenectomy. An additional 7 patients met hemodynamic criteria for surgical intervention (3 splenectomies, 4 splenorrhaphies). Admission CT was available in 63 patients. An arterial blush was identified in 5 (9.7%). Four remained stable and were treated conservatively. One underwent splenectomy for hemodynamic instability. There were no cases of delayed splenic rupture, failed nonoperative treatment, or long-term complications. Conclusions Contrast blush in children with blunt splenic trauma is rare, and its presence alone does not appear to predict delayed rupture or failure of nonoperative treatment. Based on this limited series, splenic artery embolization does not have a place in the management of splenic injuries in children.
