Phase N/A Results N/A

Trial Description

The aim of this study is to address the usefulness of carotid duplex ultrasound as vascular imaging for selecting acute stroke patients for endovascular thrombectomy.

Conditions

Interventions

  • After detection of occluded vessels by vascular imaging using carotid duplex ultrasound, digital subtraction angiography is immediately performed before acute endovascular treatment. Procedure
    Intervention Desc: 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.
    ARM 1: Kind: Experimental
    Label: carotid duplex ultrasound
    Description: 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.
