The Transcranial Doppler Appearance of Acute Carotid Artery Occlusion Ann Neurol 31:101-103, Giller,G.A.,et al, 1992 See this aricle in Pubmed Article Abstract Transcranial Doppler ultrasound is a noninvasive technique of cerebral blood velocity measurement that is being increasingly used to detect untoward hemodynamic changes.In this report,we describe striking transcranial Doppler ultrasound changes occurring in 2 patients after cervical carotid artery occlusion that led to cerebral infarction.These changes consist of the sudden appearance of a Doppler signal of extremely low pulsatility and moderately high velocity in the middle cerebral artery distribution.In 1 patient this signal was the first sign of carotid occlusion.We suggest that these transcranial Doppler ultrasound changes can provide an early warning of carotid artery compromise.
