[Transoral carotid ultrasonography].
BACKGROUND AND PURPOSE We attempted ultrasonographic evaluation of the distal extracranial internal carotid artery (ICA) using the transoral method (transoral carotid ultrasonography [TOCU]). METHODS The subjects consisted of five healthy volunteers and seven stroke patients. Examinations were performed with a color Doppler flow imaging system equipped with convex array transducers (7 or 9.5 ...
متن کاملPoststenotic flow and intracranial hemodynamics in patients with carotid stenosis: transoral carotid ultrasonography study.
BACKGROUND AND PURPOSE In severe carotid stenosis, blood supply via the poststenotic internal carotid artery (ICA) and collateral pathways determine cerebral perfusion. We investigated whether poststenotic flow on transoral carotid ultrasonography (TOCU) is predictive of cerebral hemodynamics. METHODS Eighty-eight patients with unilateral carotid stenosis underwent TOCU to analyze blood flow ...
متن کاملEvaluation 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...
متن کاملContrast‐enhanced transoral carotid ultrasonography for the evaluation of a long stenotic lesion in the internal carotid artery
Contrast-enhanced transoral carotid ultrasonography (CETOCU) is a novel modality for imaging the distal extracranial internal carotid artery, which is not possible with conventional carotid ultrasonography. We present a representative case that demonstrates the usefulness of CETOCU.
متن کاملUltrasonography 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...
