Randomized Controlled Trial Multicenter StudyCiticoline in intracerebral haemorrhage: a double-blind, randomized, placebo-controlled, multi-centre pilot study.
In experimental models citicoline has shown beneficial effects in intracerebral haemorrhage. Citicoline is a neuroprotectant drug with some beneficial effects in human ischaemic stroke and with an excellent safety profile. We decided to carry out a pilot study to test its safety and efficacy in human intracerebral haemorrhaging. ⋯ Citicoline seems to be a safe drug in human intracerebral haemorrhage with a positive trend regarding efficacy. These data should be confirmed in a larger trial.

Case Reports Randomized Controlled Trial Comparative StudySafety and therapeutical benefit of hemicraniectomy combined with mild hypothermia in comparison with hemicraniectomy alone in patients with malignant ischemic stroke.
Both for hemicraniectomy and for hypothermia, several reports describe a beneficial effect in patients with malignant supratentorial cerebral ischemia. We compared the safety and the clinical outcome in patients with a malignant supratentorial infarction who were treated with hemicraniectomy alone (HA) or received a combination therapy with hemicraniectomy and hypothermia of 35 degrees C (HH), respectively. ⋯ The present study suggests that a combined therapy of mild hypothermia and hemicraniectomy in malignant brain infarction does not imply additional risks by side effects and improves functional outcome as compared with hemicraniectomy alone.

Comparative Study Clinical TrialAnalysis of emboli during carotid stenting with distal protection device.
The newly developed multi-frequency transcranial Doppler (TCD) is able to differentiate gaseous from solid emboli. Our goal was to apply this technology to initially characterize emboli detected during carotid stenting with distal protection. ⋯ Microembolization frequently occurs during stenting even with deployment of the distal protection device. More solid emboli are seen during manipulations associated with lesion crossing. Although novel TCD methods yield a high frequency of embolic signals, further validation of this technique to determine the true nature, size, and number of emboli is needed.

Serial measurements of N-terminal pro-brain natriuretic peptide after acute ischemic stroke.
The exact time-course of N-terminal pro-brain natriuretic peptide (NT-proBNP) and the prognostic importance in the immediate phase of ischemic stroke have not been established. ⋯ NT-proBNP peaks the day after onset of symptoms in patients with acute ischemic stroke. A single measurement of NT-proBNP appears to be an indicator of 6-month mortality.

Review Case ReportsThe fetal variant of the circle of Willis and its influence on the cerebral collateral circulation.
In a fetal-type posterior circle of Willis (FTP) there is an embryonic derivation of the posterior cerebral artery (PCA) from the internal carotid artery (ICA). Besides the fact that a larger area is thus dependent on the ICA, leptomeningeal vessels cannot develop between the anterior and posterior circulation. The tentorium namely prevents cerebellar vessels from connecting to the PCA territory. ⋯ An overview of the literature is given. We propose to define a partial FTP, in which a small P1 segment between the basilar artery and the postcommunicating part of the PCA is present, and a full FTP, in which the P1 segment is absent. Whether a full FTP is a risk factor for stroke should be subject of further investigation.
