Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
carotid duplex ultrasound
Single arm study. After detection of occluded vessels by vascular imaging using carotid duplex ultrasound, digital subtraction angiography is immediately performed before acute endovascular treatment.
After detection of occluded vessels by vascular imaging using carotid duplex ultrasound, digital subtraction angiography is immediately performed before acute endovascular treatment.
When the ratio of the end diastolic velocity in the common carotid arteries is greater than 1.4 or the diastolic flow in the internal carotid artery is not detected by vascular imaging using carotid duplex ultrasound, digital subtraction angiography is immediately performed before acute endovascular treatment. If vessel occlusion is not detected by carotid duplex ultrasound, additional vascular imaging including MR angiography or CT angiography is considered.
