BACKGROUND Among patients with acute ischemic stroke due to occlusions in the proximal anterior intracranial circulation, less than 40% regain functional independence when treated with intravenous tissue plasminogen activator (t-PA) alone. Thrombectomy with the use of a stent retriever, in addition to intravenous t-PA, increases reperfusion rates and may(More)
INTRODUCTION The purpose of this article is to present the results of microsurgical clipping or endovascular coil obliteration of unruptured intracranial aneurysms (UIA), in a single cerebrovascular center with regard to successful obliteration and periprocedural complications. METHODS Data concerning patients with UIA were recorded in the neurovascular(More)
INTRODUCTION We report our first clinical experience with a CE-marked flexible monorail balloon-expandable stent for treatment of high-grade intracranial stenoses. METHODS Between April 2006 and November 2007 21 patients with symptomatic intracranial stenoses (>70%) were treated with the PHAROS stent. In seven patients, the procedure was performed during(More)
OBJECTIVES To review the angiographic and clinical outcome of patients with unruptured intracranial aneurysm(s) (UIA) with regard to complications and successful obliteration by surgical clipping or endovascular coiling. METHODS Data were derived from a prospective database of intracranial aneurysms from June 1999 to May 2005. All patients were(More)
BACKGROUND An easily accessible and valid surrogate marker for interventional stroke trials is needed. OBJECTIVE To investigate the usefulness of various S100B serum measures to predict long-term outcome and infarct volume in patients with acute stroke. DESIGN Inception cohort study. SETTING Tertiary care university hospital. PATIENTS Thirty-nine(More)
OBJECTIVE To evaluate the feasibility of PoleStar N20 (Medtronic Surgical Navigation Technologies, Louisville, KY), an ultra-low-field intraoperative magnetic resonance imaging (iMRI) system during resection control of pituitary macroadenomas and to compare intraoperative images with postoperative 1.5-T MRI images obtained 3 months after the procedure.

Intracranial stenting is increasingly used as an add-on to medical therapy despite the fact that the overall clinical benefit remains a matter of debate, since we lack results of randomized trials. Decision making on interventional treatment is made on the grounds of the anticipated risk of stroke with antiplatelet medication on one hand and on the(More)
BACKGROUND AND PURPOSE Endovascular placement of coronary balloon-expandable stents in patients with recurrent cerebral ischemia has emerged as a treatment option for intracranial arterial occlusive disease. We have developed an in vitro model matching the tortuous curve of the carotid siphon that allows the assessment of apposition of stents to a curved(More)
RATIONALE Early reperfusion in patients experiencing acute ischemic stroke is critical, especially for patients with large vessel occlusion who have poor prognosis without revascularization. Solitaire™ stent retriever devices have been shown to immediately restore vascular perfusion safely, rapidly, and effectively in acute ischemic stroke patients with(More)
