Abstract: Objective To explore the clinical features,treatment and prognosis of traumatic subdural effusion (TSE) in infants.Methods Data of 51 cases of traumatic subdural effusion in infants admitted to the single center of Dalian Women and Children Medical Center (Group) from February 2013 to February 2020 were retrospectively analyzed,and their clinical manifestations,imaging features,treatment methods and prognosis were summarized and analyzed.Results Fifty-one cases (26 males and 25 females),ranging in age from 1 month to 3 years old of traumatic subdural effusion in infants were reviewed in our hospital,all cases were confirmed by Computed Tomography (CT) examination.31 cases were treated conservatively,29 cases were cured,and 2 cases were treated surgically due to poor conservative treatment.Surgical treatment was performed in 22 cases (including 2 cases who received surgical treatment due to poor conservative treatment).One patient underwent puncture and continuous drainage at the lateral Angle of the anterior fontanelle and was cured.Twenty-one cases underwent cranial drilling,subdural space catheterization for external drainage,and 17 cases (80.95%,17/21) were cured at one time.There were 4 cases (19.05%,4/21) of recurrence after external drainage with catheterization.Two cases were cured by external drainage with Ommaya capsule insertion and intermittent aspiration and fluid drainage.It was changed to subdural peritoneal shunt surgery,and 2 cases were cured after the operation.There was no surgical infection or death in all the children in the group.The median follow-up time ranged from 3 months to 60 months,and the conditions were all stable.Conclusion Traumatic subdural effusion is a common complication after craniocerebral injury in infants and young children.Due to its lack of self-expression,the hidden condition is often ignored.Moreover,the brain tissue of infants and young children is in the growth and development stage,which will affect the development of brain tissue after its onset.
