Reliability and agreement of point-of-care carotid artery examinations by experts using hand-held ultrasound devices in patients with ischaemic stroke or transitory ischaemic attack.

ABSTRACT: To investigate the reliability and agreement of hand-held ultrasound devices (HUDs) compared with conventional duplex ultrasound (HIGH) in examination for carotid stenosis in patients with suspected transitory ischaemic attack (TIA) or ischaemic stroke. Cardiologists, experienced in carotid ultrasound, examined patients admitted to a community hospital with suspected stroke or TIA. Patients were first examined by an HUD and second by HIGH as per usual care. Different operators performed HUD and HIGH blinded to each other. On clinical discretion, CT angiography (CTA) was performed, and analysed by a radiologist blinded to the results from the ultrasound. Of 80 patients included, 9 (11%) were found to have >50% internal carotid artery (ICA) stenosis on reference examination. Agreement for cl
