Impedance methods for investigation of cerebral circulation.

摘要: Publisher Summary A number of problems pertaining to the theory and practical application methods for measuring pulsatile fluctuations cephalic impedance total changes are still unsolved. Recent studies suggest that capable providing qualitative information on regional cerebral blood flow. Thus, their importance in study circulation is expected grow. Impedance techniques great value diagnosis vascular diseases, detection circulatory disturbances brain tumors, craniocerebral trauma, so on. These methods, especially combined with different tests, may gain early atherosclerosis running an asymptomatic course or manifested by scanty non-specific psychopathologic disturbances. This, turn, will contribute prevention grave lesions brain. be used extensively effects a variety drugs circulation, thus making possible prescription well-motivated treatment patients disorders control its effectiveness. This has acute period stroke, when additional deterioration hemodynamics unfavorable even fatal consequences.
