BACKGROUND A small proportion of strokes are caused by cerebral arteriovenous malformations (AVM). Treatment to prevent intracranial haemorrhage itself carries risks, and untreated AVM may in many cases have a good prognosis. We investigated the risk of subsequent symptomatic bleeding in the clinical course of AVM in patients with and without an initial(More)
BACKGROUND AND PURPOSE Similar to digital subtraction angiography, dynamic spin labeling angiography (DSLA) provides time-resolved measurements of the influx of blood into the cerebral vascular tree. We determined whether DSLA may help in assessing the degree of stenosis and whether it provides information about intracerebral collateralization and allows us(More)
BACKGROUND Early medical complications are potentially modifiable factors influencing in-hospital outcome. We investigated the influence of acute complications on mortality and poor outcome 3 months after ischemic stroke. METHODS Data were obtained from patients admitted to one of 13 stroke units of the Berlin Stroke Registry (BSR) who participated in a(More)
OBJECTIVE To assess the potential role of cerebral microbleeds (CMB) in intracerebral hemorrhage (ICH), as indicators of cerebral small-vessel disease, and their possible implications for antithrombotic treatment. METHODS The author reviewed literature published through July 2005 from electronic MEDLINE, PubMed, and hand searches. CMB prevalence analyses(More)
PURPOSE The purpose of this study was to define the influence of feeding mean arterial pressure (FMAP) in conjunction with other morphological or clinical risk factors in determining the probability of hemorrhagic presentation in patients with cerebral arteriovenous malformations (AVMs). METHODS Clinical and angiographic data from 340 patients with(More)
BACKGROUND Ipsilateral mydriasis is known to accompany signs of cerebral ischemia in unilaterally compromised carotid blood flow. Mydriasis as the presenting sign of common carotid artery (CCA) dissection has not been reported thus far. CASE DESCRIPTION We report the case of a patient who presented with a mydriatic pupil after intraoperative injury of the(More)
OBJECTIVE To determine the extent that demographics, clinical characteristics, comorbidities, and complications contribute to the risk of in-hospital mortality and morbidity in acute stroke. METHODS Data of consecutive patients admitted to 14 stroke units cooperating within the Berlin Stroke Register were analyzed. The association of demographics,(More)
BACKGROUND AND PURPOSE Compliance with pharmacological therapy is essential for the efficiency of secondary prevention of ischemic stroke. Few data exist regarding patient compliance with antithrombotic and risk factor treatment outside of controlled clinical trials. The aim of the present study was to assess the rate of and predictors for compliance with(More)
BACKGROUND AND PURPOSE Poststroke pneumonia is a potentially preventable complication after stroke associated with poor outcome. We developed and externally validated a prognostic score for predicting risk of pneumonia after ischemic stroke. METHODS The prognostic score was developed based on clinical data routinely collected after admission from the(More)
High-intensity transient signals on transcranial Doppler sonography (TCD) are associated with atherosclerotic stenosis of the internal carotid artery. Few data exist regarding the detection of high-intensity transient signals in dissected carotid arteries. In the present study, 6 patients with spontaneous carotid dissection, defined by magnetic resonance(More)
