RESUMO
Objective To investigate the mechanism and clinical characteristics of rapid spontaneous resolution of acute subdural hematoma in children. Methods The clinical data of 9 children with rapid spontaneous resolution of acute subdural hematoma were retrospective analyzed. Results Subdural hematoma of three cases were completely dissolved within 8 h, while those of the other 6 cases were significantly reduced which were completely dissolved in 48-72 h. Conclusions Rapid spontaneous resolution of acute subdural hematoma in children is rare in clinical practice. The redistribution and dilution of hematoma and the anatomical characteristics of the children patient determine the possibility of hematoma dissipation. The conservative treatment can get a good prognosis.
