Clinical and imaging features of top of the basilar artery syndrome / 临床神经病学杂志

ABSTRACT

Objective To discuss the clinical manifestation of top of the basilar artery syndrome (TOBS) and its features of magnetic resonance imaging (MRI)/cerebral digital subtraction angiography (DSA). Method The clinical data of 30 cases with TOBS admitted during past four years were analyzed. Results The clinical manifestation of TOBS comprised the sudden vertigo and unconsciousness with the ophthalmoplegia and the abnormality of the pupils,as well as the paralysis,partial blindness or cortical blindness and ataxia and memory impairment. MRI showed the local infarction in thalami, cerebellum, midbrain, lobus occipitals , pons, temporal inner surface and splenium of corpus callosum. The features of DSA are occlusion and stenosis in basilar artery and vertebral artery. Conclusions The diagnose of TOBS depends mainly on the clinical manifestation and MRI. The DSA application in TOBS can offer the possible location of vascular lesion, and instruct treatment and prevention for TOBS.
