Using balloon-expandable stents (BES) for treatment of intracranial stenoses, high inflation pressures and rigidity of the device are regarded as major drawbacks limiting feasibility and safety of the procedure. Self-expanding stents (SES) were developed to facilitate lesion access and to allow for less aggressive dilatation. We analyzed data of the(More)
For patients with symptomatic carotid stenosis, benefit from carotid artery stenting (CAS) highly depends on the 30-day stroke and death rates. Identification of predictors of unfavourable outcome would help guide the patient selection. We analysed the influence of clinical and angiographic factors on the 30-day outcomes of 77 consecutive patients who(More)
INTRODUCTION The direct aspiration first pass technique (ADAPT) has been introduced as a rapid and safe endovascular treatment strategy in patients with ischemic stroke. OBJECTIVE To determine the technical feasibility, safety, and functional outcome with ADAPT using the new large-bore 6F SOFIA Plus catheter. METHODS A retrospective analysis of(More)
BACKGROUND AND PURPOSE Stenting is increasingly used as an adjunct to medical therapy in symptomatic intracranial stenoses. High periprocedural adverse event rates are one of the limitations of endovascular treatment. Data from the INTRASTENT multicentric registry should demonstrate in-hospital complications at the current stage of clinical development of(More)
OBJECTIVES Very few cases of arteriovenous malformations (AVMs) associated with gliomas were reported so far in the literature. METHODS Here, we report a rare case of a glioblastoma with an AVM-like lesion and review the existing literature. RESULTS We report an unusual case of a 72-year old woman, who presented with a progressive history of aphasia,(More)
Established process models for knowledge discovery find the domain-expert in a customer-like and supervising role. In the field of biomedical research, it is necessary to move the domain-experts into the center of this process with far-reaching consequences for both their research output and the process itself. In this paper, we revise the established(More)
The durability of carotid artery stenting (CAS) is affected by the occurrence of myointimal proliferation and in-stent restenosis (ISR). We aimed to identify clinical, angiographic, and laboratory predictors of ISR, paying special attention to postprocedural metabolic factors. A total of 102 consecutive patients with successful CAS for > or =70%(More)
BACKGROUND Despite the high prevalence of lumbosacral transitional vertebrae (LSTV), little is known about the segmental innervation in this condition. METHODS The authors performed a prospective comparative clinical evaluation and an intraoperative electromyographic (EMG) investigation on patients with six lumbar vertebral bodies (6LVB) and on patients(More)
