ABSTRACT
Objective To investigate the clinical manifestation characteristics of imaging,increase the diagnosis and treatment level of top of the basilar artery syndrome(TOBS). Methods Retrospective analysis of 21 clinical data with TOBS was carried out. Results More of cases were acute or subacute onset, the most common initial symptoms of vertigo, the clinical manifestation comprised unconsciousness, dismovement of the eyeballs and abnormality of the pupils. Imaging showed the feature of the TOBS was infarction in both sides of the midbrain and thalamencephalon, and multiple lesions exist. Conclusion The clinical manifestation of.TOBS were diverse, and only by grasping the characteristics of the TOBS raising awareness ,early diagnosis,standardized treatment and improving prognosis would be possibe.
ABSTRACT
Objective To study the clinical and neuroimaging features of top of the basilar artery syndrome(TOBS).Methods The clinical and neuroimaging features of 63 cases with TOBS were analyzed retrospectively.Results Main causes of TOBS were atherosclerosis and embolisms.Vertigo and disturbance of consciousness and movement of the eye-ball,abnormality of pupils,partial blindness were the main clinical features.The most important imageologic feature of TOBS was infarction of thalami or midbrain,which was frequently complicating with infarction in other locations.Conclusion TOBS has simultaneously more than two infarction lesions,either superior or inferior tentorium of cerebellum with many complications and poor prognosis.MRI is more sensitive than CT.Early MRI examination,systemic and comprehansive treatment may improve the prognosis of the TOBS patients.
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.
