Risk Factors Related To Traumatic Hydrocephalus And Hydrocephalus After Decompression Craniectomy For Patients With Craniocerebral Trauma

Background:Traumatic hydrocephalus after craniocerebral injury is one of important reasons with severe disabilities and high mortality rate.if patients did not have effective treatments,they lead to searious consequences due to increased intracranial pressure.Currently,the diagnosis and classification standards did not confirmed.Hydrocephalus is defined as the creation and absorption of cerebrospinal fluid imbalance, with ventricular system expanded, the most importent classification method for communicative and obstructive hydrocephalus, rely on where the cerebrospinal fluid circulation path is blocked, if the part of the block is above arachnoid granulations, the ventricle above blockage is enlargement, called obstructive hydrocephalus; if the blockage in the arachnoid granulations level for communicative hydrocephalus, with all intraventricular and subarachnoid space enlargement, this kind of classification method is helpful to the choice of clinical treatment.The causes of the formation of water on the brain, such as bleeding, meningitis, craniocerebral injury, Risk of fators for hydrocephalus after brain trauma have not been studied systematically. Recently,Decompressive craniectomy has become the preferred treatment with patients after severe brain trauma.But the hydrocephalus after Decompressive craniectomy increas the patients suffering.So,exploring the factors related the post-decompressive craniectomy hydrocephalus is important.Objective: to find the risk factors related to traumatic hydrocephalus and hydrocephalus after decompression craniectomy for patients with craniocerebral trauma.Methods:This research contains760patients of traumatic brain Injure form June2008to2013including126cases of traumatic hydrocephalus. There are124cases by decompressive craniectomy in the706cases, which contain30cases of hydrocephalusendoscopicBy the method of systematic review,the research explore the risk factors of traumatic hydrocephalus, and the risk fators of post-decompressive craniectomy hydrocephalus.Results:In the760patients of traumatic brain njure,126cases of traumatic hydrocephalus, the ncidence of hydrocephalus is17.46%.Through The Logistic regression analysis, we conclud that:the occurrence of hydrocephalus is relevant to age, brain injury scope, a subdural hematoma, post-traumatic subarachnoid hemorrhage(tSAH), coma and so on; there were significant differences of the two Groups in whether underwent bilateral craniectomy (p<0.01),height of craniectomy (P<0.01),area of craniectomy(P<0.01), whether underwent reoperation (P<0.01)Conclusion:The degree of coma after injury, subarachnoid hemorrhage, intraventricular hemorrhage, subdural hemorrhage, bilateral decompressive craniectomy, height and area of bone window are risk fators for the development of post-traumatic hydrocephalus.
