Neurointerventional radiology or endovascular neurosurgery refers to special minimally invasive procedures to diagnose and treat vascular disorders of the brain and spine. With the help of advanced imaging for guidance, neurointerventionalists or neurosurgeons use microcatheters (tiny tubes) to treat many complex disorders. Normally these disorders are treated either by closing (embolization) or opening (recanalization) the abnormal vessels. The neurointerventional device market encompasses neurothrombectomy devices (suction/aspiration device, clot retriever, and snare device), cerebral angiography and stenting system (carotid stent, and embolic protection system), aneurysm coiling devices (platinum coil, liquid embolic agents, and flow diversion device) and support devices (microcatheter, and microguidewire).
There is no association between MS (multiple sclerosis) and venous narrowing, specifically the narrowing of the veins from the brain to the heart (extracranial veins), researchers reported in The Lancet.
Madrid, noviembre de 2013. Mañana, viernes 8 de noviembre, se celebra, por segundo año de manera coordinada en todo el mundo, el Día Internacional de la Radiología, con el objetivo de transmitir a la sociedad el valor de la radiología en la detección precoz, diagnóstico y tratamiento de todo tipo de enfermedades y su contribución al cuidado de la salud de los ciudadanos.
La radiocirugía se consolida como alternativa a la cirugía en determinados tipos de tumores cerebrales benignos La Escuela Española de Oncología Radioterápica (EEOR) celebra en Valencia el “II curso de tumores y metástasis del sistema nervioso central: posibilidades de tratamiento radioterápico actual”
A new study has found that age should be a consideration when planning a carotid intervention. The authors of the study state that there is an increased risk of adverse cerebrovascular events when carotid stenting is carried out in elderly patients when compared with younger patients (odds ratio: 1.56; 95% CI, 1.40–1.75 vs. 0.94; 95% CI. 0.88–0.99)
With the development of the Surpass FD, we engineered the porosity and mesh density of braided tubular implants to optimise the effect of intra-aneurysmal flow reduction for a given size of the parent artery harbouring the aneurysm, writes Ajay K Wakhloo.
“The results of laser ablation to treat inoperable brain tumours, epilepsy and refractory cancer pain are very exciting,” Shabbar F Danish, director, Stereotactic and Functional Neurosurgery and assistant professor at Rutgers-Robert Wood Johnson Medical School and Robert Wood Johnson University Hospital, New Brunswick, USA, told NeuroNews.
A tool devised from combining weighted inputs of three variables (Age, National Institute of Health Stroke Scale (NIHSS) at presentation and CT leptomeningeal collateral score), proved to be strongly correlated with functional outcome in acute stroke.
In carotid artery stenosis patients undergoing open heart surgery, staged carotid artery stenting demonstrated to have the best outcomes compared to staged and combined carotid endarterectomy and open heart surgery. The results of the retrospective comparison conducted at the Cleveland Clinic appear online in the Journal of the American College of Cardiology.
Some of the most important trends in stroke therapy involve further developments in the area of thrombolytic therapy as well as new insights into the mechanical removal of blood clots in acute strokes through minimally invasive catheter procedures, according to Werner Hacke, University of Heidelberg, and vice president of the World Federation of Neurology, at the XXI World Congress of Neurology (Vienna, 21–26 September 2013)
Aquilla Turk, from the department of Radiology, MUSC, Charleston, USA, presented a case showing how well a technique works that uses a direct aspiration first pass with a large bore aspiration catheter as the primary method for vessel recanalisation at the fifth European Society of Minimally Invasive Neurological Therapy (ESMINT) congress (5–7 September, Nice, France)
MicroVention, Inc. (Tustin, CA), a wholly owned subsidiary of Terumo Corporation (Tokyo, Japan), announced initiation of enrollment in a multicenter, prospective, pivotal clinical trial in the United States to demonstrate the safety and efficacy of the company’s flow diversion system called FRED (flow-redirection endoluminal device), for treating intracranial aneurysms. The FRED system has received CE Mark approval for use in Europe and several other international markets.
A retrospective, multicentre series, published in Neurosurgery in September, demonstrates that stent-assisted coiling with two stents in a Y configuration has a low rate of complications, a low incidence of re-treatment and in-stent stenosis. Good outcome was obtained in 93% of patients at the last follow-up.
The new version of the Revive SE thrombectomy device offers enhanced navigation through the cerebral vasculature and rapid restoration of blood flow to the brain after an ischaemic stroke. The announcement was made at the 5th Congress of European Society of Minimally Invasive Neurological Therapy (ESMINT) in Nice, France.
The Fred (Flow Redirection Endoluminal Device) system is a dual-layer stent that is CE marked in European countries and several other international markets where clinical cases have already been performed.
