开颅术后张力性气颅

报告１９８８年１２月～１９９２年１２月开颅术后张力性气颅５例，男４，女１．５例中３例治愈，２例死亡。开颅术后张力性气颅产生的主要原因是颅内占位性病变切除后，脑脊液丢失，使颅内压降低，甚至呈负压状态，外界的气体从切口进入颅内的腔隙，ＣＴ扫描或颅骨Ｘ线平片可以确定诊断，钻孔置管排气是活疗张力性气颅的有效方法，作者探讨了预防此种并发症发生的措施。

Tention Pneumocephalus After Craniotomy

This paper reports 5 cases,one male and four females,of tension pneumocephalus after craniotomy from Dec 1988 to Dec 1992,4 maks and 1 female.3 of 5 cases were cured,and 2 died.An analysis is made of main causes producing tension pneumocephalus after surgery,ie.resection of intracranial space-occupying lession,lost cerebrospinal fluid,the formation of intracranial pressure fall and even of negative pressure.Thus extraneous air gets into intracranial space,The CT scan or plain skull may suggest the correct diagnosis Frontal twistdrill holes and a pipe into subdural space is a good air-exhaustion method for the treatment of tension pneumocephalus. The preventive measures are developed for this complication.
