Abstract:
Objective To analyze the clinical characteristics and the positions of asymptomatic cerebral infarction (ACI) in flying personnel,and to explore its risk factors.Methods The clinical data of flying personnel in our hospital who had been diagnosed as ACI by brain magnetic resonance imaging (MRI) were reviewed.The cases were divided into multiple group and single group by the number of infarctions.Statistical analysis was performed to assess the risk factors between two groups.Results Thirty-five cases of aircrew with ACI were analyzed,among which 28 cases (80.0％) had diagnosed risk factors of cerebrovascular diseases,and 12 (34.3％) had single risk,16 (45.7％) had more than one risk factors.The main risk factors included cerebral atherosclerosis,hypertension and smoking habit.We also found that the ischemic lesions were mainly located at the basal ganglia and subcortical white matter.Single group and multiple group respectively contained 14 and 21 cases.The average flight time was statistically significant between the two groups (P＜0.05).Conclusions The main risk factors of ACI in flying personnel including hypertension and cerebral atherosclerosis.The positions of ACI are mainly located at the subcortical white matter and basal ganglia.
