BACKGROUND AND PURPOSE Predictors of clinical outcome in aneurysmal subarachnoid hemorrhage (SAH) vary in reliability. Measurement of cerebral venous hemodynamics by transcranial color-coded duplexsonography (TCCS) has become of increasing interest lately, and correlation with intracranial pressure (ICP) seems to be high. The aim of the presented study was(More)
OBJECTIVES To evaluate in a prospective multicentre setting the feasibility of transcranial colour coded duplex sonography (TCCS) for examination of the middle cerebral artery (MCA) in patients with acute hemispheric stroke, and to assess the validity of sonographic findings in a subgroup of patients who also had a correlative angiographic examination.

OBJECTIVE Superficial siderosis of the central nervous system (CNS) is a rare chronic progressive disorder caused by chronic subarachnoid hemorrhage. We present four patients with superficial siderosis of the CNS to describe the characteristic symptoms, and to discuss the pathogenetic heterogeneity and possible new therapeutic approaches. RESULTS The(More)
BACKGROUND AND PURPOSE It remains uncertain whether the annual stroke risk of 7% to 8% in middle cerebral artery (MCA) stenosis is of embolic or hemodynamic origin. Preliminary reports provide evidence of emboli exiting from acute MCA stenoses, detected by transcranial Doppler (TCD) sonography. With multirange monitoring before and after the stenosis, TCD(More)
Atherosclerotic stenoses of the intracranial vessels are less frequent than those of the extracranial vessels, but they are associated with a considerable annual stroke rate. The aim of the present study was to investigate the usefulness of frequency-based transcranial color-coded sonography (TCCS), transcranial Doppler sonography (TCD) and digital(More)
BACKGROUND AND PURPOSE Cerebral emboli can be recognized by typical "high-intensity transient signals" (HITS) in the transcranial Doppler (TCD) spectral curves. Patients with potential cardiac sources of embolism are at higher risk for stroke. METHODS We examined the frequency of HITS in the left middle cerebral artery (MCA) with TCD over periods of 30(More)
BACKGROUND AND PURPOSE Carotid artery stent placement (CAS) may be associated with clinically silent cerebral lesions. We prospectively evaluated the association of the number of solid cerebral microemboli during unprotected CAS with the frequency of silent cerebral lesions as detected by diffusion-weighted MR imaging (DWI). METHODS We performed(More)
BACKGROUND We aimed to analyse the course of early recanalization and corresponding functional outcome in patients with an acute occlusion of the carotid T who were treated conservatively or underwent intravenous thrombolysis. METHODS Forty-two patients with an acute occlusion of the carotid T within 6 h were recruited from consecutive admissions to a(More)
OBJECTIVE Alerted by the number of patients with transient global amnesia (TGA) in whom Valsalvalike activities immediately preceded the onset of TGA, we have investigated the frequency of patent foramen ovale (PFO) as the prerequisite for paradoxical embolism. DESIGN Case series with comparison to a control group. SETTING Hospitalized and ambulatory(More)
Fifty patients with multiple sclerosis were treated either by corticosteroids given systemically or by intrathecal injection of a steroid crystal suspension. Before and 3 weeks after the beginning of the treatment we examined the patients according to the Expanded Disability Status Scale (EDSS). Four patients had to be excluded from evaluation. In 23(More)
