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

Abstract

The dynamics of cerebral blood flow in acute ischemic strokewas studied with allowance for a pathogenic classification ofstroke. Analysis of the ultrasound parameters demonstrated thatparticular attention should be given to quantitative, rather thanqualitative, parameters of blood flow. The dynamics of cerebralblood flow in different etiologies of cerebral stroke is reflectedin specific changes in the linear velocities, which relates a strokesubtype to the factors determining the need for extended monitoring.Clinical and instrumental assessment of the developmentof hemodynamic disorders during reperfusion after stroke bymeans of Doppler ultrasound demonstrated that, depending onthe etiology of ischemic stroke, recovery of the intracerebral hemodynamicsparameters to normal values occurs differently andhas its features that, if timely detected, may affect correction ofthe strategy and tactics of treatment. Based on these data, we suggesta differentiated algorithm of extended Doppler monitoringof cerebral blood flow in acute ischemic stroke.
