We studied the trigeminal nerve in seven healthy volunteers and six patients with trigeminal neuralgia using the diffusion tensor imaging derived parameter fractional anisotropy (FA). While controls did not show a difference between both sides, there was a reduction of FA in the affected nerve in three of six patients with accompanying nerve-vessel conflict(More)
Trigeminal neuralgia (TN) is a pain state characterized by intermittent unilateral pain attacks in one or several facial areas innervated by the trigeminal nerve. The somatosensory cortex is heavily involved in the perception of sensory features of pain, but it is also the primary target for thalamic input of nonpainful somatosensory information. Thus, pain(More)
BACKGROUND Emergency reversal of the international normalized ratio (INR) in patients who develop nontraumatic subdural hemorrhage (SDH) due to oral anticoagulants (OAC) represents a primary treatment strategy but it is difficult to predict the amount of prothrombin complex concentrate (PCC) needed for reversal treatment. Moreover, repeated INR testings in(More)
A newly-born infant with a congenital dural and bony defect and an associated short-segmented duplication of the superior sagittal sinus suffered from herniation and infarction of parietal brain tissue secondary to vacuum extraction. This ultimately led to the formation of a subgaleal cerebrospinal fluid (CSF) collection. Initial operative closure of the(More)
BACKGROUND AND PURPOSE Flow-diverter stents are emerging for the endovascular treatment of difficult-to-treat or otherwise untreatable cerebral aneurysms (wide-neck, fusiform, dissecting, blisterlike, or giant). We assessed the clinical safety and efficacy of the Flow-Redirection Endoluminal Device. MATERIALS AND METHODS This was an institutional review(More)
Background: The association of mortality and poor outcome with reduced levels of hemoglobin (Hb) and hematocrit (Hct) in patients admitted for ischemic stroke was recently demonstrated. The mechanisms behind this have remained unclear. Aims: Here, we aimed to investigate a pu-tative association between low Hb and Hct levels and infarct growth. Methods: All(More)
BACKGROUND AND PURPOSE Basilar artery occlusion remains one of the most devastating subtypes of ischemic stroke. The prognosis is poor if early recanalization is not achieved. The purpose of this study was to evaluate the safety and technical feasibility of self-expanding retrievable stents in the endovascular treatment of acute basilar artery occlusion. (More)
BACKGROUND AND PURPOSE Thrombolysis in patients using oral anticoagulants (OAC) and in patients for whom information on OAC status is not available is frequently delayed because the standard coagulation analysis procedure in central laboratories (CL) is time-consuming. By using point-of-care (POC) coagumeters, international normalized ratio (INR) values can(More)
BACKGROUND AND PURPOSE Several recent studies analyzing perfusion changes in acute intracerebral hemorrhage fed the debate whether there is secondary ischemic tissue damage in the vicinity of intracerebral hemorrhage. We used perfusion CT to address this question. METHODS We examined 36 patients between 2001 and 2002 with acute intracerebral hemorrhage(More)
BACKGROUND AND PURPOSE The purpose of this study was to evaluate the safety and technical feasibility of a new thrombectomy device (Revive; Micrus Endovascular) in the endovascular treatment of acute ischemic stroke. METHODS Ten patients with acute large vessel occlusions were treated with the Revive device between October 2010 and December 2010. Mean(More)
