Abstract:
Objective:To provide references for the diagnosis and aeromedical evaluation by analyzing the data of the flying personnel with cerebral arterial stenosis.Methods:The clinic and aeromedical evaluation data of the flying personnel, who were diagnosed as cerebral arterial stenosis when they hospitalized in Air Force Medical Center from September of 2009 to September of 2019, were reviewed.Results:Eight male flying personnel, aged 32-53 years old, were diagnosed as cerebral arterial stenosis. Five out of 8 flying personnel had the history of hypertension or smoking, and 2 suffered from arteritis. Among 3 neurological impairment cases, 1 was left carotid artery stenosis and 2 was middle cerebral artery stenosis or occlusion. Those 3 flying personnel were disqualified by aeromedical evaluation. The other 5 flying personnel without neurological impairment included 1 case of left subclavian artery stenosis with left renal artery stenosis, 1 case of intracranial stenosis of the left internal carotid artery, 2 cases of middle cerebral artery stenosis or occlusion, and 1 case of left anterior cerebral artery stenosis. Among them, 4 cases were diagnosed as silent brain infarction. The cerebral perfusion evaluation of those 4 cases indicated normal perfusion of the diseased vessels blood supply. Aeromedical waiver was decided upon the diagnosis as well as the considerations on the aircraft type they flied and their flight duty.Conclusion:The cerebral artery stenosis is living in flying personnel and atherosclerosis would be the main cause. Such clinical features as ischemic stroke or no neurological impairment may occur. The waiver should be considered according to the situations of cerebral perfusion and neurological impairment.
