Insights
Infantile acute subdural hematoma (aSDH) can lead to chronic subdural hematoma if not treated promptly. Early recognition and intervention are crucial for improving outcomes in infants with aSDH.
Area of Science:
- Pediatric Neurosurgery
- Trauma Surgery
- Neonatal Medicine
Background:
- Infantile acute subdural hematoma (aSDH) presents unique challenges compared to adults due to differing injury mechanisms and the frequent consideration of nonaccidental trauma.
- Understanding the specific clinical patterns and management of aSDH in infants is critical for appropriate care.
Purpose of the Study:
- To analyze the clinical characteristics of acute subdural hematoma in infants.
- To identify common patterns of trauma leading to infantile aSDH.
- To outline management principles for infantile aSDH.
Main Methods:
- Retrospective review of medical records and imaging (CT/MRI) for 21 infants diagnosed with aSDH.
- Analysis of patient demographics, injury cause, clinical presentation, surgical interventions, and outcomes.
- Comparison of outcomes based on treatment strategies (conservative vs. surgical) and injury severity (GCS scores).
Main Results:
- Shaken baby syndrome was the most frequent cause of aSDH in infants.
- Common presentations included seizures, retinal hemorrhages, and altered consciousness.
- Conservative management of smaller hematomas led to chronic subdural hematoma in 11 of 13 infants, necessitating surgical drainage.
- Overall good recovery was observed in 62% of patients, with outcomes correlating to initial Glasgow Coma Scale (GCS) scores.
Conclusions:
- Untreated or conservatively managed infantile aSDH is a significant precursor to infantile chronic subdural hematoma.
- Timely diagnosis and appropriate treatment are essential to mitigate severe morbidity and potential fatality.
- Prompt intervention can significantly improve the prognosis for infants with acute subdural hematoma.
Background:
Acute subdural hematoma in infants is distinct from that occurring in older children or adults because of differences in mechanism, injury thresholds, and the frequency with which the question of nonaccidental injury is encountered. The purpose of this study is to analyze the clinical characteristics of acute subdural hematoma in infancy, to discover the common patterns of this trauma, and to outline the management principles within this group.
Methods:
Medical records and films of 21 cases of infantile acute subdural hematoma were reviewed retrospectively. Diagnosis was made by computed tomography or magnetic resonance imaging. Medical records were reviewed for comparison of age, gender, cause of injury, clinical presentation, surgical management, and outcome.
Results:
Twenty-one infants (9 girls and 12 boys) were identified with acute subdural hematoma, with ages ranging from 6 days to 12 months. The most common cause of injury was shaken baby syndrome. The most common clinical presentations were seizure, retinal hemorrhage, and consciousness disturbance. Eight patients with large subdural hematomas underwent craniotomy and evacuation of the blood clot. None of these patients developed chronic subdural hematoma. Thirteen patients with smaller subdural hematomas were treated conservatively. Among these patients, 11 developed chronic subdural hematomas 15 to 80 days (mean = 28 days) after the acute subdural hematomas. All patients with chronic subdural hematomas underwent burr hole and external drainage of the subdural hematoma. At follow-up, 13 (62%) had good recovery, 4 (19%) had moderate disability, 3 (14%) had severe disability, and 1 (5%) died. Based on GCS on admission, one (5%) had mild (GCS 13-15), 12 (57%) had moderate (GCS 9-12), and 8 (38%) had severe (GCS 8 or under) head injury. Good recovery was found in 100% (1/1), 75% (8/12), and 50% (4/8) of the patients with mild, moderate, and severe head injury, respectively. Sixty-three percent (5/8) of those patients undergoing operation for acute subdural hematomas and 62% (8/13) of those patients treated conservatively had good outcomes.
Conclusions:
Infantile acute subdural hematoma if treated conservatively or neglected, is an important cause of infantile chronic subdural hematoma. Early recognition and suitable treatment may improve the outcome of this injury. If treatment is delayed or the condition is undiagnosed, acute subdural hematoma may cause severe morbidity or even fatality.
