The causes and treatment of acute encephalocele during craniotomy on head-injured patients

to uncover the causes,clinical features, early diagnosis and treatment of acute encephalocele during craniotomy on head-injured patients. Methods The causes of encephalocele were analyzed according to the expanding velocity and the character of the injured brain, the hit sites of the head and cranial CT scans. Results 25 cases of encephalocele were treated, 11 died, the mortality was 44%. Conclusion It should be awared to and prepare for the encephalocele caused by delayed hematoma before craniotomy. The time of brain oppression by contralateral hematoma should be shortened to the minimum during operationo As for the encephalocele due to vessel paralysis,the emphasis should be put on preventing anoxia before craniotomy, decompression must be sufficiento Lumbar puncture promptly and correctly after craniotomy would be helpful to improve the prognosis.
