Influencing factors for posttraumatic hydrocephalus in patients suffering from severe traumatic brain injuries

Objective:To detect the influencing factors for posttraumatic hydrocephalus in patients with severe traumatic brain injuries and provide theoretical reference for clinical treatment. Methods:Retrospective study was made on 139 patients with severe traumatic brain injuries in our hospital.The patients were divided into two groups:hydrocephalus group and non-hydrocephalus group.Single factor analysis and multiple factor analysis were used to determine the related factors and hydrocephalus.Multiple factor analysis was conducted with logistic regression. Results:Posttraumatic hydrocephalus was found in 19.42% of patients.Age(OR=1.050,95% CI:1.012- 1.090),decompressive craniectomy(OR=4.312,95 % CI: 1.127-16.503),subarachnoid hemorrhage(OR=43.421, 95% CI:7.835-240.652)and continuous lumbar drainage of cerebrospinal fluid(OR=0.045,95 % CI:0.011-0.175) were screened out from nine factors as the influencing factors for posttraumatic hydrocephalus. Conclusions:Risk factors for PTH are as follows:age, decompressive craniectomy and subarachnoid hemorrhage (SAH).Continuous lumbar drainage of cerebrospinal fluid can greatly reduce posttraumatic hydrocephalus.
