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)
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)
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 We aimed to analyze the association between patient socioeconomic status and functional impairment 3 months after ischemic stroke and to identify factors that influence this association. METHODS Data were obtained from the Berlin Stroke Register, a network of 14 stroke units in Berlin. Ischemic stroke patients consecutively admitted(More)
OBJECTIVE Neurovascular compression of the rostral ventrolateral medulla (RVLM) has been implicated in the pathogenesis of essential hypertension. Although MRI has been widely used to evaluate the morphologic relation of structures in this region, spatial resolution of the previously used techniques was limited. This article describes the use of a new MRI(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)
BACKGROUND AND PURPOSE Safety and efficacy concerns toward thrombolysis for ischemic stroke prevail among many neurologists because of the risks of hemorrhage and the small proportion of suitable patients. We therefore prospectively assessed feasibility, safety, efficacy, and team performance in a single center to prove whether thrombolytic treatment is(More)
