Abstract
BACKGROUND: The optimal management of nonacute subdural fluid collections in infantile abusive head trauma (AHT) remains controversial. OBJECTIVE: To review the outcomes and costs of the various treatments for symptomatic subdural fluid collections in children with AHT at a single center. METHODS: Our AHT database was queried to identify children requiring any intervention for hematohygromas. Demographic, hospital course, radiologic, cost, readmission, and follow-up information were collected. RESULTS: From January 2009 to March 2018, the authors identified 318 children with AHT, of whom 210 (66%) had a subdural collection of any type (blood or cerebrospinal fluid). A total of 50 required some form of intervention specifically for chronic hematohygromas. The initial management consisted of transfontanelle percutaneous aspiration (n = 31), burr holes with (n = 12) or without (n = 3) external subdural drainage, and mini-craniotomy (n = 4). Of those who were initially managed with 1 or more needle aspiration, 23 (74%) required further intervention-12 subduroperitoneal shunts and 11 nonshunt procedures. No patient who underwent burr holes/external drainage required further intervention (n = 16). Overall, the average number of interventions needed in these 50 children for definitive treatment was 1.8 (range, 1-4). A total of 15 children ultimately required a subduroperitoneal shunt. Complications (infectious, hemorrhagic, and thrombotic) were significant and occurred in all treatment groups except burr holes without drainage (n = 3). The average hospital charge for the entire cohort was $166 300.25 (range, $19 126-$739 248). CONCLUSION: Based on our experience to date, burr hole with controlled external subdural drainage is an effective and preferred treatment for traumatic hematohygromas; complications and need for additional intervention is low.
