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)
OBJECT This study was designed to determine whether the frequency of shunt-dependent hydrocephalus in patients suffering from aneurysmal subarachnoid hemorrhage (SAH) differs when comparing surgical clip application with endovascular obliteration of ruptured aneurysms. METHODS In this prospective nonrandomized study, 245 patients with aneurysmal SAH(More)
Twenty-seven patients with 14 aneurysms and 17 vascular malformations were each examined with both time-of-flight (TF) and phase-contrast (PC) magnetic resonance angiography of the head. Three-dimensional (3D) PC imaging depicted the patent lumen of the aneurysms, while 3D TF imaging depicted the patent lumen and a subacute thrombus if present. The 3D PC(More)
PURPOSE To describe a new fluoroscopically guided technique for osteoplasty (or cementoplasty) of the superior and inferior pubic rami and ischial tuberosities and to provide information about the access routes and initial results on pain management after this technique. MATERIALS AND METHODS Twenty-three lytic metastases of the superior and inferior(More)
Atherosclerotic plaques that develop in the extracranial circulation are usually extensively vascularized by vasa vasorum. However, human vasa vasorum associated with intracranial atherosclerosis has not been adequately addressed. Anterior and posterior circulation specimens from fresh autopsy material were studied under the magnification of a dissecting(More)
PURPOSE To assess the effectiveness, initial and long term, of embolization using polyvinyl alcohol particles (PVA) particles in patients with spinal dural arteriovenous fistulas (SDAVF). METHODS The initial treatment in 14 patients with SDAVF was embolization with PVA particles. Postembolization occlusion of the SDAVF was documented angiographically in(More)
Major cerebral thromboembolism often resists recanalization with currently available techniques. The authors present their initial experience with a self-expanding stent for use in intracranial vascular reconstruction, permitting immediate recanalization of acute thromboembolic occlusions of the anterior circulation. Patients treated with the Cordis(More)
SUMMARY Atheromatous stenoses at the carotid bifurcation were treated by angioplasty and Wallstenting with cerebral protection obtained in most cases by temporary occlusion of the internal carotid artery. 287 carotid stenoses were treated in 233 patients. The stenosis was symptomatic in 79% of cases. All patients presented either a stenosis of >70% with(More)
Spinal magnetic resonance angiography (MRA) is difficult to perform because of the size of the spinal cord vessels. High-field MR improves resolution and imaging speed. We examined 17 patients with spinal vascular diseases with dynamic contrast-enhanced three-dimensional MR sequences. In three patients, the artery of Adamkievicz could be seen; we could also(More)
Bone pain and functional impairment are major concerns for multiple myeloma (MM) patients. The goal of this study was to better define the role of percutaneous cementoplasty (PC) in improving their quality of life. This retrospective analysis included 28 consecutive heavily pretreated MM patients managed at our institution between 1996 and 2002. They(More)
