To assess if the initial grade of splenic injury depicted at computed tomography (CT) in children could help predict rate of healing.
Thirty-seven children with splenic injury graded at emergent CT were prospectively followed up with non-enhanced and contrast material-enhanced CT performed 2 weeks to 11 months after injury.
In all 15 grade 1 and 2 splenic injuries, healing was seen at follow-up, including eight injuries that occurred in patients who underwent follow-up CT within 4 months. In 10 of 11 grade 3 splenic injuries, healing was seen within 6 months. In all 11 grade 4 injuries, residual lesions were seen within 4 months and healing took up to 11 months. Five of nine residual splenic injuries were more clearly visualized with contrast material enhancement. No splenic complications occurred.
CT grade of splenic injury is related to rate of healing. Grade 1 and 2 injuries typically heal within 4 months, whereas grade 3 injuries take up to 6 months to heal and grade 4 injuries take up to 11 months.
评估儿童计算机断层扫描（CT）显示的脾损伤初始分级是否有助于预测愈合速度。
对37例在急诊CT上分级的脾损伤儿童进行前瞻性随访，在损伤后2周至11个月进行非增强和对比剂增强CT检查。
在所有15例1级和2级脾损伤中，随访时可见愈合，包括8例在4个月内接受随访CT检查的患者的损伤。在11例3级脾损伤中的10例中，6个月内可见愈合。在所有11例4级损伤中，4个月内可见残留病变，愈合时间长达11个月。9例残留脾损伤中有5例在对比剂增强下更清晰可见。未发生脾并发症。
脾损伤的CT分级与愈合速度有关。1级和2级损伤通常在4个月内愈合，而3级损伤需要长达6个月愈合，4级损伤需要长达11个月愈合。
