Logistic Regression Analysis of Relationship between Changes of Cerebrospinal Fluid and Communicating Hydrocephalus after Decompressive Craniectomy in Craniocerebral Injury under Computed Tomography Images

Abstract

This paper aimed to explore the application value of CT imaging in the correlation analysis of communicating hydrocephalus (CH) after decompressive craniectomy (DC) of craniocerebral injury (CI). 410 patients with craniocerebral trauma who were admitted to the hospital from October 2015 to October 2019 were taken as subjects, among which 130 patients suffered from CH. All patients underwent craniocerebral CT examination, and logistic regression was applied to analyze the risk factors of hydrocephalus in CI and hydrocephalus after DC surgery. The results showed that the coma time (OR = 5.1283, $P=0.001$ ), subarachnoid hemorrhage (SAH) (OR = 7.6543, $P=0.020$ ), Glasgow Coma Scale (GCS) score no more than 8 points (OR = 3.5480, $P=0.001$ ), intraventricular hemorrhage (OR = 2.2653, $P=0.003$ ), cerebral contusion and laceration (OR = 1.036, $P=0.002$ ), and subdural hemorrhage (OR = 2.4376, $P=0.001$ ) were independent risk factors for CH. Bilateral DC (OR = 15.342, $P=0.023$ ), second surgery (OR = 7.021, $P=0.004$ ), bone window height (OR = 6.543, $P=0.041$ ), and bone window area (OR = 1.035, $P=0.012$ ) were independent risk factors for CH after DC surgery. It suggested that CT imaging technology could be utilized in the diagnosis of CI. The risk factors of CH included coma time, SAH, GCS score no more than 8, intraventricular hemorrhage, brain contusion, subdural hematoma, bilateral DC, bone window height, bone window area, and second surgery.
