CO-RELATION BETWEEN TRANSCRANIAL DOPPLER SONOGRAPHY, CALORY TEST OF VESTIBULARIS AND ELECTRONISTAMOGRAPHY IN CASE OF VERTEBRO BALISAR INSUFFICIENCY

Introduction Transcranial Doppler Sonography is non-invasive, ultrasound diagnostic method, which provides insight into the status of hemodynamic of the frontal carotid and rear VB system, as well as such method of selection it diagnosis of VB insufficiency. This method is in use since 1982. For the purpose of confirmation of VB insufficiency diagnosis are used test o: calorie testing of vestibularis and electronystagmograyphy, as additional method in some cases. Materials Subjects and Methods During the work were made analyses of group of 50 individuals witl symptoms of VB Insufficiency, age of 40 - 60 years, and control group of 5( healthy individuals of the same age. From all individuals were taken history neurology examination, laboratory results (blood count, sugar in blood lypidogram and blood pressure), ophthalmologic examination, EKG anc cardiology examination, RTG of neck spine, transcranial Doppler (TCD) calorie test of vestibularis, test of electronystagmography, EEG and CT o brain. Work results After examination by transcranial Doppler using sonography, pathological (reduced) value of SBSK were found in investigative group with 30% o individuals AV right, in control group only 12%, but AV left was found with 54% in investigative group and only 10% in control group, in AB with 52% individuals in investigative group and with 8% in control group. Calorie test of vestibularis was pathological in investigative group with 78% o individuals, but in control group only with 14% of individuals: the majority findings were asymmetric and areflectic. 88% of individuals in investigative group had pathological test o electronystamography, but in control group only 16%. Statistic is significant among groups in all three mentioned groups. Conclusions: 1. Transcranial Doppler sonography is method of selection in establishment of diagnosis of VB insufficiency. 2. This is diagnostic method which gives the information on neurovascular disorder in case of VB insufficiency. 3. Additional diagnostic methods, application of calorie test o vestibularis and test of electronystagmography before all, provide objective diagnosis of VB insufficiency with 90% of individuals.
