BACKGROUND AND PURPOSE The purpose of this study was to assess the initial post-market experience of the device and how it is compared with the Penumbra Pivotal trial used to support the 510k application. METHODS A retrospective case review of 157 consecutive patients treated with the Penumbra system at seven international centers was performed. Primary(More)
Complications after ischaemic stroke, including both neurological and medical complications, are a major cause of morbidity and mortality. Neurological complications, such as brain oedema or haemorrhagic transformation, occur earlier than do medical complications and can affect outcomes with potential serious short-term and long-term consequences. Some of(More)
OBJECTIVES The purpose of this study is to demonstrate the technical success of carotid artery stenting in acute extracranial internal carotid artery (ICA) occlusion as well as the benefit in clinical outcome. BACKGROUND Stroke caused by acute occlusion of the ICA is associated with a significant level of morbidity and mortality. For this type of lesion,(More)
BACKGROUND AND PURPOSE This is the first single center experience illustrating the effectiveness of the penumbra system (PS) in the treatment of large vessel occlusive disease in the arena of acute ischaemic stroke. The PS is an innovative mechanical thrombectomy device, employed in the revascularization of large cerebral vessel occlusions in patients via(More)
Obwohl die Vorteile bildwandlergestützter Navigationssysteme offensichtlich sind, ist die Genauigkeit der Pedikelschraubenplatzierung mit “virtual fluoroscopy” im klinischen Alltag noch unzureichend evaluiert. In einer prospektiven Studie wurden 160 Pedikelschrauben mit dem bildwandlergestützten ION-Navigationssystem (Medtronic Surgical Navigation(More)
The aim of this study was to evaluate the risks of endovascular therapy, aneurysm regrowth, recanalization and the need for reembolization. A prospective analysis was performed on 211 aneurysms treated endovascularly from February 2000 to December 2003. Of these 211 aneurysms, 81 were asymptomatic and 130 were ruptured. The risks of endovascular therapy,(More)
Cardiovascular disease is the leading cause of death worldwide with almost one-third of all cardiovascular deaths ascribed to stroke. Imaging modalities, such as CT, MRI, positron emission tomography (PET), and single photon emission CT (SPECT) provide tremendous insight into the pathophysiology of acute stroke. Computed tomography is considered the most(More)
Die moderne Bildgebung hat einen besonderen Stellenwert bei der Diagnostik und Therapie von Schädelbasispathologien. Zahlreiche Läsionen können anhand ihrer CT- und MRT-Befunde, insbesondere unter Berücksichtigung ihrer genauen Lokalisation, artdiagnostisch eingeordnet werden. Im Bereich der vorderen Schädelbasis sind v. a. Karzinome, Rhabdomyosarkome,(More)
While the advantages of C-arm navigation in computer-assisted spine surgery are obvious, the accuracy of pedicle screw placement with virtual fluoroscopy still needs to be verified. The C-arm-based ION system (Medtronic Sofamor Danek) was used to navigate pedicle screw insertion in patients undergoing spinal surgery for various conditions. In a prospective(More)
AIMS The aim was to determine the incidence of new ischaemic lesions on diffusion-weighted MR imaging (DWI) in a non-randomised cohort of patients after protected and unprotected carotid artery stent placement using the Parodi Anti-Emboli System (PAES). METHODS AND RESULTS A retrospective review was conducted on 269 patients who received DWI prior to, and(More)
