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.

Although the foregoing review of embryologic development and congenital anomalies of the spine in infants and children is necessarily brief, the most commonly encountered abnormalities have been reviewed, and when possible, an attempt has been made to cite the stage of embryologic development at which the various abnormalities originate. As noted, congenital abnormalities of the spine are relatively uncommon but may be of profound clinical significance. During the past decade, the most significant developments in the diagnosis and treatment of these abnormalities have been ultrasonography, CT scanning, and MR imaging. In the neonate, the spinal cord and neural outflow can be evaluated by ultrasonography until the osseous elements begin to fuse. Thereafter, MR imaging is the procedure of choice because it permits evaluation of the spine and spinal cord in all planes of imaging and provides detailed evaluation of the effect of osseous abnormalities on neural structures. Finally, plain radiographs of the spine for evaluation of neonates who have any of a spectrum of sacral dimples are rarely helpful, and in the presence of significant cutaneous or subcutaneous abnormalities, ultrasonography is the preferred modality for evaluation.
