Brachiocephalic Vessels Ultrasound Index of Arteriovenous Ratio (IAVR) and Headache as a Diagnostic Tool for Intracranial Venous Stasis in Arterial/Venous Ischemic Stroke’s Differentiation

Abstract

Identification of signs of intracranial venous stasis using ultrasound methods in combination with determination of headache intensity according to the visual-analogue scale allows us to suspect the venous genesis of ischemic stroke before using neuroimaging methods, which can contribute to the selection of adequate therapy and to improve the prognosis and long-term outcomes of the disease.
