Transcranial color-coded duplex sonography for detection of distal internal carotid artery stenosis.
BACKGROUND AND PURPOSE Gradation of high-grade intracranial internal carotid artery (ICA) stenosis poses a challenge to noninvasive neurovascular imaging, which seems critical for angioplasty in the ICA segments C1 and C5. We investigated cutoff values of intracranial ICA stenosis for transcranial color-coded sonography (TCCS) and compared this method with the "gold standard," digital subtracti...
متن کاملReduced Internal Carotid Artery Flow in Color-coded Carotid Duplex Sonography.
PURPOSE Reduced flow in the internal carotid artery (ICA) is related to cerebral ischemia. We established a classification of reduced ICA flow through color-coded carotid duplex (CCD) sonography. METHODS We retrospectively reviewed 25,000 CCD images in sonography laboratory. RESULTS Reduced ICA flow [flow volume (FV) less than 100 mL/min] was found in 1.2% of all studies, and 270 patients w...
متن کاملTranscranial color-coded duplex sonography in unilateral flow-restrictive extracranial carotid artery disease.
PURPOSE To provide transcranial color-coded duplex flow-velocity data for the basal cerebral arteries in patients with unilateral flow-restrictive extracranial carotid artery disease, and to compare these data with the flow velocities obtained in healthy control subjects. METHODS Transcranial color-coded duplex sonography was performed in 78 patients with different patterns of cross flow thro...
متن کاملCoiled distal internal carotid artery (ICA) aneurysm in transcranial sonography
Figure 1. A. Axial brain computed tomography (CT)angiography showing a giant left (Lt) distal internal carotid artery (ICA) aneurysm. B. Axial transcranial sonogram (mesencephalic level): Butterfly-shaped midbrain was encircled for better visualization (solid lines). Arrows indicate the coiled distal ICA aneurysm. He was monitored via daily transcranial sonography (TCS) for the potential develo...
متن کاملCarotid and transcranial color-coded duplex sonography in different types of carotid-cavernous fistula.
BACKGROUND AND PURPOSE Patients with carotid-cavernous fistula (CCF) may undergo direct or indirect shunting. Ultrasonography has value that is complementary to angiography in the assessment and follow-up of these patients. The aim of this study was to characterize findings provided by carotid duplex sonography (CDS) and transcranial color-coded duplex sonography (TCCD) in patients with differe...
