Factors Associated with Nontraumatic Spontaneous Subdural Hematomas in Pediatric Patients

Abstract

Abstract Objective In our study, we aimed to summarize the etiology of subdural hematoma that was not traumatic and required operation in pediatric patients. The subdural hematoma characteristics, possible etiologies, and treatment, as well as the patient outcomes, were analyzed. Methods A retrospective examination was made of pediatric patients with subdural hematoma who were operated on at Ümraniye Training and Research Hospital. Patients with a history of trauma were excluded. Data on patient sex, age, bleeding location, type of hematoma based on computed tomography imaging, surgical treatment, presenting symptoms, presence of comorbidities, Glasgow Coma Scale, thrombocyte counts, and international normalized ratio values were recorded. Results Of the 19 patients included in the study, 4 were female and 15 were male. Their ages ranged between 0 and 15 (mean = 5.84) years. In 57.8% of the patients, comorbidities, including acute myeloid leukemia, a history of shunt operation, epilepsy, mucopolysaccharidosis, known subdural effusion, autism, coagulopathy, ventricular septal defect/tetralogy of Fallot, cerebrospinal fluid leakage after baclofen pump administration, Marfan's syndrome, and late neonatal sepsis were present, while 21% had arachnoid cysts and 21% had no reported comorbidities. Conclusion This study suggests that, in pediatric patients with subdural hematoma with an amount of bleeding requiring surgical management, any underlying comorbidities should be investigated regardless of the presence of a history of trauma. While investigating systemic diseases, special attention should be paid to the presence of arachnoid cysts or disruption in cerebrospinal fluid dynamics along with a history of hematologic diseases.
