Doppler sonography characteristics of vertebrobasilar circulation in patients with Parkinson's disease.

The objective of the study was to analyze the doppler sonography findings of vertebrobasilar circulation (VB) in patients with Parkinson's disease. 40 patients were analyzed (25 men's and 15 women) with Parkinson's disease, average age was 61.9 years (SD=11.43), treated at the Clinic for Neurology in Tuzla. Device for doppler sonography was Multidop x 4. Doppler sonography findings of VB circulation were analyzed in order to computerized tomography (CT) findings of the brain (with or without ischemic lacunar lesions) and in order to presence of postural disturbances as one of dominant Parkinson's disease symptoms during actual hospitalization. Our results suggest that vertebrobasilar insufficiency is more frequent in patients with Parkinson's disease (no matter of type) and postural disturbances as a dominant symptom comparing to group of Parkinson's disease patients without postural disturbances. These results implicate the importance of doppler sonography findings of vertebrobasilar circulation in patients with Parkinson's disease and possibility of considering role of vertebrobasilar insufficiency in development of postural disturbances.
