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.
In Stroke, Carmelo L. Sturiale, MD, et al published findings from a systemic review and meta-analysis of endovascular treatment of intracranial aneurysms in elderly patients (2013;44:1897–1902). The investigators were from the Mayo Clinic in Rochester, Minnesota, and led by Giuseppe Lanzino, MD. They noted in the background of the study that the use of endovascular coiling for treating ruptured and unruptured intracranial aneurysms in the elderly is increasing, so they performed a meta-analysis of the literature examining clinical and angiographic outcomes.
A study presented at the Society of NeuroInterventional Surgery (SNIS) meeting (29 July–1 August, Miami, USA) suggests that the use of a balloon guide catheter with the Solitaire Stent retriever in acute ischaemic stroke results in superior recanalisation results, faster procedure time, decreased need for rescue therapy, and improved clinical outcome.
Zoll Medical Corporation (Chelmsford, MA) announced that it has purchased the assets of CoAxia, Inc. (Maple Grove, MN). Zoll Medical Corporation, which is a manufacturer of medical devices and related software solutions, is one of a diversified group of companies of the Asahi Kasei Corporation (Tokyo, Japan). CoAxia is an early revenue-stage medical device company that provides catheter-based perfusion augmentation therapies to improve outcomes for patients with cerebral ischemia resulting from vasospasm after subarachnoid hemorrhage.
Gore & Associates (Flagstaff, AZ) announced commencement of enrollment in SCAFFOLD, the Gore Carotid Stent Clinical Study for the Treatment of Carotid Artery Stenosis in Patients at Increased Risk for Adverse Events from Carotid Endarterectomy.
In the case of mild or moderate strokes, getting treatment ultra-fast (within 90 minutes of experiencing symptoms) greatly reduces the risk of suffering disability, according to a new study reported in the American Heart Association’s journal, Stroke.
There is no evidence that impaired blood flow or blockage in the veins of the neck or head is involved in multiple sclerosis, says a study from McMaster University.
Data from the registry was presented at EuroPCR, Paris, France, in May 2013. The data reflects a single-centre experience of carotid artery stenting in a small cohort of 65 diabetic patients.
On 8 July, Penumbra announced the launch and wide availability of the 5Max Ace, a next generation clot extraction device that uses aspiration alone to engage and remove blood clots that cause an acute ischaemic stroke.
At the Society for Vascular Surgery (SVS) Vascular Annual Meeting (30 May–1 June 2013, San Francisco, USA), Jeffrey Jim, Washington School of Medicine, St Louis, USA, presented registry data on the differences in adverse events after carotid revascularisation between men and women with carotid artery stenosis
