Evaluation of carotid artery stenosis using three-dimensional ultrasonography

Three-dimensional color Doppler sonography in carotid artery stenosis.

BACKGROUND AND PURPOSE Color Doppler sonography (CDS) suffers from such disadvantages as high interobserver variability and problems with data presentation and storage. We therefore performed a prospective trial to assess the role of three-dimensional CDS (3D-CDS) in the evaluation of internal carotid artery stenosis (ICAS). METHODS We included 32 consecutive patients with sonographically ver...

Ultrasonography of carotid stenosis

The classification of internal carotid artery stenosis is of great impact. The degree of stenosis is the main criterion for the decision between an invasive or non-invasive treatment of extracranial internal carotid artery (ICA) stenoses. By now the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria have been internationally approved for radiological grading. According to...

Evaluation and Treatment of Carotid Artery Stenosis

Carotid artery stenosis grading using CT angiography: Evaluation Based on Carotid Area Stenosis Index

Evaluation of distal extracranial internal carotid artery by transoral carotid ultrasonography in patients with severe carotid stenosis.

BACKGROUND AND PURPOSE Conventional ultrasonography techniques do not allow visualization of the distal cervical segment of the internal carotid artery (ICA). In a study of patients with severe ICA stenosis, we performed transoral carotid ultrasonography (TOCU) to assess its ability to image this segment of the artery. METHODS The study participants consisted of 20 consecutive patients who ha...
