Thromboembolic complications following pediatric spinal fusion surgery are rare (21 per 10,000) but are more strongly associated with older age and specific diagnoses like congenital or syndromic scoliosis.
The incidence of thromboembolic complications in children was approximately 21 events per 10,000 spinal fusions. A higher incidence of VTE in children was associated with older age and certain diagnoses (congenital scoliosis, syndromic scoliosis/kyphoscoliosis, and thoracolumbar fractures). PE in children was rare and not associated with fatality.
Jain et al. (Tue,) studied this question.
