IRVINE, Calif.--(BUSINESS WIRE)--Blockade Medical LLC, a privately held company focused on the development of catheter based therapeutic devices for the treatment of cerebral aneurysms, announced today that more than 100 patients have been successfully treated with the Barricade Coil SystemTM. The patients treated, presented with a wide range of cerebral aneurysms and peripheral lesions. All treated patients had positive clinical outcomes without any reported complications.
Phenox has announced that the pCONus Bifurcation Aneurysm Implant has been granted CE mark approval for commercialisation within the European Union and any country that accepts CE mark approval. The pCONus implant is a new category of intraluminal stent intended to treat complex, wide neck intracranial bifurcation aneurysms.
A study led by Fabrice Bing, University of Montreal Hospital Research Center, Notre-Dame Hospital, Montreal, Canada, and published ahead of print in Neuroradiology has tested the safety and efficacy of high-porosity and flow-diverting stents to treat intracranial aneurysms when used in vivo.
Some stroke patients may benefit from cerebral angioplasty and stent placement, according to a new study published online ahead-of-print in the 11 December issue of the journal Radiology.
Strokes, particularly those classified as severe, were uncommon after carotid intervention in the CREST trial. Strokes, however, were associated with significant morbidity and future mortality, a new analysis of the trial has shown. In the sub-analysis, published online ahead of print in Circulation, the authors stated that these strokes may be preventable.
The first US patient to enrol in the ADvance study was successfully implanted with a deep brain stimulation (DBS) system from Functional Neuromodulation. ADvance will evaluate the safety and potential clinical benefit of DBS of the fornix (DBS-f), a major inflow and output pathway in the brain s memory circuit, for patients with mild Alzheimer s.
By Adnan H Siddiqui, Elad I Levy, L Nelson Hopkins and Kenneth V Snyder. Our group of Neurosurgery at University at Buffalo, New York, USA, has been performing carotid endarterectomy for more than 30 years and carotid artery stenting since 1994. We have participated in virtually all carotid artery stenting trials in the USA and have been co-principal investigators or executive committee members for most. Our experience includes over 2000 carotid endarterectomy and 3000 carotid artery stenting procedures. The largest and most comprehensive randomised trial to date has been the CREST trial (Carotid revascularisation endarterectomy vs. stenting), which demonstrated equivalence overall with more minor strokes with carotid artery stenting and more myocardial infarctions with carotid endarterectomy, in spite of first-generation technology and limited experience. Myocardial infarction had a significant impact on long-term mortality, as did major stroke. Patients with minor strokes after carotid artery stenting improved significantly at six and 12 months, and these strokes did not have an impact on long term-survival. Moreover, CREST commenced only six years after carotid artery stenting was first performed in the USA. Carotid artery stenting results improved in the latter half of the trial as experience and judgment improved. So what have the trials taught us about the usefulness of carotid artery stenting?
On 4 December, InSightec announced that its transcranial focused ultrasound system, ExAblate Neuro, has been awarded the CE mark for the treatment of neurological disorders including: essential tremor, Parkinson’s disease and neuropathic pain.
A study, published in CardioVascular and Interventional Radiology, has investigated the possibility of collaboration between vascular interventional radiologists, diagnostic neuroradiologists and stroke neurologists for neurointerventional treatment of acute stroke as a strategy for centres lacking of specialised interventional neuroradiologists.
Madrid, Noviembre de 2012.- La Sociedad Española de Neurorradiología ha concedido unánimemente el “Premio a la profesión en Radiología" al neurorradiólogo del hospital Gregorio Marañón, Francisco Villoria Medina, en reconocimiento a la extraordinaria labor profesional que desempeña en este centro sanitario de la Comunidad de Madrid, y que le ha sido entregado en un acto conmemorativo del día internacional de la Radiología.
A new study has found that diffusion tensor imaging may be able to predict which patients who have experienced concussions will improve. The results, presented at the annual meeting of the Radiological Society of North America (RSNA), suggest that, in some patients, the brain may change to compensate for the damage caused by the injury.
Marc Ribo, Unitat d’lctus, Hospital Vall d’Hebron, Barcelona, Spain, and colleagues, in a study published ahead-of-print in the Journal of Neurointerventional Surgery, said that difficult catheter access to the carotid artery during endovascular treatment of stroke patients is common and is associated with worse clinical outcomes.
Alejandro M Spiotta, Department of Neurosurgery, Medical University South Carolina, Charleston, USA, reported his team’s experience with the new balloon-stent technique for intracranial aneurysm treatment using the Scepter C balloon catheter and the LVIS, a low-profile visualised intraluminal stent.
By John R Adler Jr and Robert Dodd. Intramedullary spinal cord AVMs are rare lesions with an estimated incidence of only 0.02/100,000 person-years. Having a proclivity to affect young adults, this rare condition is associated with progressive spinal cord ischaemia and a significant risk of haemorrhage, often resulting in paralysis. Despite advances in microsurgery and intravascular embolization, many AVMs are not amenable to curative therapies because of their intra-parenchymal spinal cord location and/or a common anterior spinal artery blood supply. Even in very experienced hands, microsurgery and intravascular embolization—both established therapies—are associated with a considerable risk of complications. As a result, there are no good treatment options for many, if not most, intramedullary spinal cord AVMs.
Data from the large SAPPHIRE WW Worldwide registry suggest that age, symptomatic status, and physiological entry criteria represent high risk features for carotid artery stenting. Christopher Metzger, Wellmont CVA Heart Institute, Kingsport, USA, national co-principal investigator of the registry, presented periprocedural results of 15,000 carotid artery stenting patients at the TCT conference in Miami.
