Spontaneous resolution of acute traumatic subdural hematoma: a report of 12 cases and literature review

Abstract

Objective To analyze the clinical data and treatment of spontaneous resolution of acute traumatic subdural hematoma, and review the relative literatures to improve the knowledge of the disease. Methods The clinical manifestation, images, treatment and prognosis of 12 patients with spontaneous resolution of acute traumatic subdural hematoma, admitted to our hospital from June 2005 to June 2014, were concluded and analyzed. Results Non-surgical treatment was adopted in all the patients; complete obliteration of hematoma within 24 h of injury was noted in 4 and obvious decrease was noted in 8; complete obliteration of hematoma in all patients was achieved within 72 h of injury. Average days of hospitalization was 18. All patients enjoyed good prognosis and no system function defects were noted at discharge. Conclusion Patients with acute traumatic subdural hematoma of sane, middle shift<5 mm, hematoma thickness<10 mm and no cisterna apparent oppression or disappearance may need conservation management with close clinical observation and dynamic CT images. Whose possible mechanisms of spontaneous resolutionmay might be associated with the dilution of cerebrospinal fluid and the fracture of skull.
