Transcranial 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. ...
متن کاملThree-dimensional transcranial color-coded sonography of cerebral aneurysms.
BACKGROUND AND PURPOSE The role of 2-dimensional transcranial color-coded sonography (2D-TCCS) as a diagnostic tool in cases of vascular alteration is unquestioned. The skill of the operator, however, may be responsible for some intertrial variability. The clinical value of a new, workstation-based, 3D reconstruction system for TCCS was evaluated in patients with intracranial aneurysms. METHO...
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 کاملFrontal bone windows for transcranial color-coded duplex sonography.
BACKGROUND AND PURPOSE The use of the conventional temporal bone window for transcranial color-coded duplex sonography (TCCS) often results in difficulties in obtaining angle-corrected flow velocity measurements of the A2 segment of the anterior cerebral artery, the posterior communicating artery, and the midline venous vasculature because of the unfavorable insonation angle. The same applies t...
متن کاملCerebral Circulatory Arrest Detected by Transcranial Color-Coded Duplex Sonography: A Feasible Diagnosis for Intensivists.
Brain death is clinically diagnosed by verification of the absence of brain stem reflexes, motor responses, and the ventilatory drive.1 In some circumstances, ancillary tests are necessary to confirm the diagnosis of brain death, especially when there is uncertainty about the reliability of parts of the neurologic examination or when an apnea test cannot be performed. Ancillary tests are also u...
