Transcranial Doppler on detecting special structure of intracranial artery:three cases report
As an important method to detect intracranial arterial stenosis or occlusive disease,transcranial Doppler(TCD)has been widely used in clinical practice because of its low price and easy operation.The scope of application of TCD includes,but is not limited to,the diagnosis and collateral evaluation of intracranial artery stenosis or occlusive disease,intraoperative monitoring of carotid endarterectomy,assessment of brain death,etc.,but the characteristics of TCD blood flow changes of some special structures of intracranial arteries need to be improved.This paper presented 3 cases with special intracranial artery structures,and comprehensively analyzes the blood flow spectrum on TCD based on medical images,in order to improve clinicians'exploration experience on similar cases and the level of cerebrovascular ultrasound.
