Transcranial Doppler (TCD) is an easy, noninvasive, relatively cheap tool to investigate the reactivity of
cerebral
microvessels to vasodilative stimuli (
cerebral
vasoreactivity
), and thus it is able to assess the compensatory vasodilation of
cerebral
arterioles [1, 3, 10, 20, 23].
Transcranial Doppler (TCD) is an easy, noninvasive, relatively cheap tool to investigate the reactivity of cerebral microvessels to vasodilative stimuli (cerebral vasoreactivity), and thus it is able to assess the compensatory vasodilation of cerebral arterioles [1, 3, 10, 20, 23].
It should be mentioned that flow velocity is monitored in the main intracranial arteries (mostly in the middle cerebral artery), while the vasodilative stimuli change the diameter of the small resistance vessels (Fig. 1). TCD is an excellent method to detect cerebral microemboli as well [9, 11]. Unilateral presence of microembolic signals in the middle cerebral artery (MCA) indicates artery-to-artery embolisms from unstable carotid plaque. In addition, carotid ultrasound may also help differentiate high-risk and low-risk plaques in the internal carotid artery. Carotid plaques with irregular surface, intraplaque haemorrhage, decreased echogenicity and without echogenic cap belong to high-risk plaques.
