[Clinical analysis of 16 children with traumatic basal ganglia stroke]

Objective: To investigate the clinical characteristics and risk-factors of traumatic basal ganglia stroke (TBGS) in children. Methods: A retrospective case study was conducted to analyze the clinical and imaging data of 16 children with TBGS in the First Hospital of Jilin University from January 2014 to June 2017. A total of 16 TBGS cases (11 males, 5 females) were diagnosed and the age ranged from 0.5 to 13.0 years. The prognosis of children with TBGS at different ages (≥5 years and<5 years) and with different traumatic stroke (infarction and hemorrhage) were compared. Fisher 's test was used to compare the prognosis of different groups. Results: All cases had clear history of head trauma and varying degrees of limb paralysis after injury, including 4 cases of facial paralysis, 3 cases of consciousness disturbance and 1 case of seizures. Head CT scan of the 16 cases showed 11 cases of ischemic stroke and 5 cases of hemorrhagic stroke. Moreover, scattered calcification was observed in the bilateral basal ganglia point of 8 cases. Neurotrophic treatment, microcirculation improvement and nerve rehabilitations were given according to the clinical and imaging data. One patient was treated with craniotomy and hematoma clearance. Of the 16 cases, 11 cases were restored to normal, while 3 cases developed limb paralysis and 2 cases died. The prognosis of 11 cases of traumatic basal ganglia infarction (10 cases recovered and 1 case remained hemiplegic) was relatively better than that of 5 cases of hemorrhage (1 case recovered, 2 cases remained hemiplegic and 2 cases died) (χ(2)=8.045, P=0.013). In addition, the children younger than 5-year-old (all 8 cases recovered) had a better prognosis than the children older than 5-year-old (8 cases, 3 of whom recovered, 3 cases remained hemiplegia, 2 cases died)(χ(2)=12.121, P<0.01). Conclusions: The anatomical characteristics of basal ganglia and calcification of the lenticulostriate artery are risk-factors for TBGS in children. The prognosis of infarcted children and younger children is relatively better.
