Assessment of >/=50% and <50% intracranial stenoses by transcranial color-coded duplex sonography.
BACKGROUND AND PURPOSE A favorable risk-benefit ratio for warfarin compared with aspirin has been reported for the prevention of major vascular events in symptomatic >/=50% intracranial stenoses. Transcranial color-coded duplex sonography (TCCS) criteria providing an accurate detection of >/=50% and <50% stenoses of the anterior, middle, and posterior cerebral arteries and basilar and vertebral...
متن کاملContrast-enhanced three-dimensional transcranial color-coded sonography of intracranial stenoses.
BACKGROUND AND PURPOSE Intracranial stenoses are associated with a considerable number of strokes each year. The clinical value of a workstation-based three-dimensional (3D) reconstruction system for transcranial color-coded sonography was evaluated in patients with intracranial stenosis or occlusion. METHODS Twenty-six patients (13 men, 13 women; mean age, 57 years +/- 12 [SD]) with 36 intra...
متن کاملTranscranial color-coded duplex sonography of intracerebral hematomas in adults.
BACKGROUND AND PURPOSE It is well established from pediatric experience and animal experiments that intracerebral blood can be demonstrated by B-mode real-time duplex scanning. This has recently become feasible in adults as well. The present study investigated the changes in the sonographic appearance of intracerebral hematomas over the course of time. METHODS Starting in May 1991, 23 consecu...
متن کاملTranscranial Color-Coded Duplex Sonography of Intracranial Veins and Sinuses in Adults
Background and Purpose—Transcranial color-coded duplex sonography (TCCS) of intracranial veins and sinuses in adults is a new, emerging application of ultrasonographic imaging. This study reports a standardized examination protocol for venous TCCS and provides reference data for clinical application. Methods—In 130 healthy volunteers (mean age, 45.9616.9 years; range, 14 to 77 years) the intrac...
متن کاملTranscranial color-coded duplex sonography in cerebral aneurysms.
BACKGROUND AND PURPOSE Diagnosis and successful therapy before rupture of cerebral aneurysms would be most desirable in view of the high mortality and morbidity rates of aneurysmal subarachnoid hemorrhage. Using transcranial color-coded duplex sonography, we studied radiologically proven cerebral aneurysms to define ultrasonographic criteria and sensitivity for their diagnosis and detection. ...
