Report of 34 cases of diffuse axonal injury

Objective: To investigate the pathogenesis,diagnosis,treatment and prognosis of diffuse axonal injury(DAI).Methods: The clinical data of 34 cases of DAI were analyzed retrospectively.Results: Among the 34 cases of DAI,21 were due to traffic accidents,10 to crashing and 3 were caused by other accidents.According to Glasgowcoma score(GCS),the recovery was good in 16 cases,moderate disability was observed in 10 cases,severe disability in 3 cases,vegetative state in 3 cases,and mortality in 2 cases.Conclusions: The mechanism of DAI is quite complicated.Traffic accidents and crashing are the major causes.Conscious disturbance is the typical clinical manifestation.MRI is superior to CT in diagnosis of DAI.Comprehensive interventions should be applied in the treatment of DAI.The outcome is closely associated with GCS and coma time.
