[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 کاملThree-dimensional Volumetric Ultrasonography of Enlarged Adrenal Gland in Dog
Objective: Detection and evaluation of adrenal glands are complex problems in conventional ultrasonography in dogs. Using three-dimensional (3D) ultrasonography (US) in adrenal gland volume evaluation can add new potential for further adrenal studies. Design: Descriptive study Animals: a total of 10 mix breed dogs Procedures: The dogs underwent two dimensional (2D) and 3D US of the adrenal g...
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 کاملThree-dimensional ultrasonography for the evaluation of atherosclerotic stenoses of the carotid trunk.
Three-dimensional ultrasonography is a significant novelty in neurosonology as it offers the possibility of an even more successful evaluation of atherosclerotic stenoses of the carotid trunk than previous ultrasonographic investigations. In 37 patients with signs of transitory ischemic attack and in 5 patients with reversible ischemic neurologic deficit we compared the findings of three-dimens...
