Extended Doppler monitoring of cerebral blood flow in different subtypes of ischemic stroke

Abstract

The dynamics of cerebral blood flow in acute ischemic stroke was studied with allowance for a pathogenic classification of stroke. Analysis of the ultrasound parameters demonstrated that particular attention should be given to quantitative, rather than qualitative, parameters of blood flow. The dynamics of cerebral blood flow in different etiologies of cerebral stroke is reflected in specific changes in the linear velocities, which relates a stroke subtype to the factors determining the need for extended monitoring. Clinical and instrumental assessment of the development of hemodynamic disorders during reperfusion after stroke by means of Doppler ultrasound demonstrated that, depending on the etiology of ischemic stroke, recovery of the intracerebral hemodynamics parameters to normal values occurs differently and has its features that, if timely detected, may affect correction of the strategy and tactics of treatment. Based on these data, we suggest a differentiated algorithm of extended Doppler monitoring of cerebral blood flow in acute ischemic stroke.
