Un estudio preliminar realizado en un centro de investigación de Gran Bretaña arrojó una evolución positiva en los pacientes que se despertaron con síntomas de un accidente cerebrovascular (ACV) tras haber sido tratados con trombolisis.
PHILADELPHIA--(Healthcare Sales & Marketing Network)--InfraScan, a medical device company specializing in brain injury diagnostic products, announced today that it has obtained U.S. Food and Drug Administration approval to market the Infrascanner™ Model 2000, a noninvasive handheld brain hematoma detector.
Covidien ($COV) may have U.S. and regulatory approvals in place for its Solitaire FR, a clot-retrieval device meant to restore blood flow to the brain for patients with acute ischemic strokes. But the company is plowing ahead with a large post-approval study to gather more data on treatment and outcomes.
Takahisa Mori, Shonan Kamakura General Hospital Stroke Center, Kamakura City, Kanagawa, Japan, and colleagues reported on their first experience of transbrachial carotid artery stenting using a novel sheath guide in the Journal of NeuroInterventional Surgery.
A study, published in the Journal of NeuroInterventional Surgery and conducted by Brijesh P Mehta, Division of Neurointerventional Radiology, Massachusetts General Hospital and Harvard Medical School, Boston, USA, and colleagues, has assessed the variability in neurointerventional practice for intra-arterial therapy with tPA for patients with major acute ischaemic stroke secondary to large vessel occlusions.
Covidien has announced the launch of a new study SWIFT PRIME (Solitaire FR as primary treatment for acute ischaemic stroke), which has enrolled its first patient at the University at Buffalo, USA. The new multicentre, randomised controlled trial will be one of the largest global studies to examine the adjunctive use of mechanical thrombectomy during the early stages of acute ischaemic stroke onset.
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.
