Clinical characteristics and related risk factors of Infarction secondary to severe traumatic brain injury

Objective To investigate the clinical characteristics and related risk factors of infarction secondary to severe traumatic brain injury.Methods 480 traumatic brain injury patients were chosen.Depending on the occurrence of cerebral infarction,patients were divided into TCI groups and non-TCI group,clinical symptoms and signs of TCI group were observed,and its related risk factors was analyzed.Results In 480 cases patients,there were 30 cases of patients with traumatic brain injury secondary to cerebral infarction,the rate was 6.25%.Clinical manifestations included unilateral limb motor and sensory dysfunction,visual dysfunction,language dysfunction,dizziness,headache.10 cases Prognosis were good,6 cases were mild disability,3 cases were severe disability,1 case was plant survival,10 patients died.Univariate analysis showed that the rates of aged ≥50 years,GCS score ＜ 8 points,hernia,hypotension,subarachnoid hemorrhage,large doses of non-dehydrating agent in the TCI group were higher than those of non-TCI group,the differences were statistically significant (x2 =12.311 3,14.725 4,19.867 8,5.296 9,9.242 6,11.713 6,all P ＜ 0.05).Logistic multivariate analysis showed that age ≥50 years,GCS score ＜ 8 points,hernia,cerebral hypotension were important risk factors.Conclusion Brain injury patients with cerebral infarction secondary to clinical manifestations have some characteristics.Age ≥50 years,GCS score ＜ 8 points,hernia,hypotension are important risk factors.
