The clinical and MRI features of top of the basilar artery syndrome in elderly population

Objective To explore the clinical and MRI features of top of the basilar artery syndrome (TOBS) in elderly population.Methods Twenty-eight TOBS patients who were above 65 years old were selected,TOAST classification and NIHSS were adopted to investigate their clinical and MRI features.Results The clinical manifestations were diversified.Vertigo and consciousness disorder were the most common features,ocular motility disorders,hemianopsia and ataxia were also frequent characteristics.As for the distributions of MRI lesions,midbrain infarction accounted for 64%,pons,thalamus,occipital lobe and cerebellar hemisphere accounted for 36%,43%,39%and 68%,respectively.These features were different from those in ordinary population. Conclusion TOBS among elderly population has its unique characteristics,mastering these characteristics is conducive to the correct understanding of such disease and the further diagnosis and therapy.
