Progression of extracranial @entity66 is considered to be significant independent predictor in the evaluation of individual cerebrovascular prognosis. Doppler ultrasonography is a useful screening method in the diagnosis and evaluation of extracranial @entity66 . The aim of this study was to establish the most sensitive hemodynamic parameter of Doppler-ultrasonographic spectral analysis in clinical evaluation of extracranial @entity66 . Investigation included 90 @entity1 (of both sexes) in hospital and outpatient clinic care. Spectral analysis (M-scanning technique) was used for the evaluation of hemodynamic status of carotid sinus, including the following parameters: Pourcelot (A-D/A), Gosling (A/B), and Mol (A/D) resistance parameters. After statistical processing the results of the research affirmed hemodynamic parameters' values and correlation between Pourcelot hemodynamic parameter and the degree of @entity543 rho = 0.59 for all @entity1 , and rho = 0.58 for @entity1 with pathological values. Correlation between Mol parameter and the degree of @entity543 was rho = 0.50 for all @entity1 , and rho = 0.57 for @entity1 with pathological values. Gosling parameter was not significantly different in mean value and was present in all three groups. Functional relationship between the degree of @entity543 and each of hemodynamic parameters was established. It was concluded that Pourcelot and Mol parameters were significant indicators of asimptomatic @entity66 , but Pourcelot parameter was considered as a more sensitive indicator in the evaluation of extracranial @entity66 .
