The regional Neurology meeting re-opened the issue of local pathways to thrombectomy. The access to most advanced techniques seems slowed by ETS procedures and lack of full week coverage 7/7.
Anticoagulant therapy is recommended for the secondary prevention of stroke in patients with atrial fibrillation (AF). T he identification of patients at high risk for early recurrence, which are potential candidates to prompt anticoagulation, is crucial to justify the risk of bleeding associated with early anticoagulant treatment. The aim of this study was to evaluate in patients with acute ischemic stroke and AF the association between findings at trans-thoracic echocardiography (TTE) and 90 days recurrence. In consecutive patients with acute ischemic stroke and AF, TTE was performed within 7 days from hospital admission. Study outcomes were recurrent ischemic cerebrovascular events (stroke or TIA) and systemic embolism. 854 patients (mean age 76.3 ± 9.5 years) underwent a TTE evaluation; 63 patients (7.4 %) had at least a study outcome event. Left atrial thrombosis was present in 11 patients (1.3 %) among whom 1 had recurrent ischemic event. Left atrial enlargement was present in 548 patients (64.2 %) among whom 51 (9.3 %) had recurrent ischemic events. The recurrence rate in the 197 patients with severe left atrial enlargement was 11.7 %. On multivariate analysis, the presence of atrial enlargement (OR 2.13; 95 % CI 1.06-4.29, p = 0.033) and CHA2DS2-VASc score (OR 1.22; 95 % CI 1.04-1.45, p = 0.018, for each point increase) were correlated with ischemic recurrences. In patients with AF-associated acute stroke, left atrial enlargement is an independent marker of recurrent stroke and systemic embolism. The risk of recurrence is accounted for by severe atrial enlargement. TTE-detected left atrial thrombosis is relatively uncommon.

In this touching second chapter, Francesca and Roberto take us through the ideas and actions that followed the first TED talk. How it changed and is still impacting not only their lives but also the people who are experiencing the same challange. Be parents of a child who had a prenatal stroke.
Francesca, Roberto and Mario ( their son) were first on the TED Global stage in 2013. From then on their life changed a lot and a lot of projects took life. On our stage they share their experience and achievements. From Inspiring to activate.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
As the first European Stroke Organisation Conference has drawn to a close, I want to thank all faculty members and delegates for their intellectual and practical support to the preparation and delivery of what has I believe been an outstanding success. When the overwhelming wish of our association was expressed just 11 months ago that we should establish a new conference, we barely dared to hope for 800-1,000 delegates in our first year. The reality was that 84 countries were represented in Glasgow, and that delegate numbers were close to 2,700. To accompany the presentations to a packed auditorium in our first plenary session alone there were two simultaneous online publications in the New England Journal of Medicine and one in Lancet, and we had new results presented from two additional fresh NEJM publications and an Annals of Neurology paper. In the afternoon, we heard the first multicentre, blinded RCT of an experimental approach in stroke, a stem cell RCT, the complete results of the desmoteplase programme and a further new thrombectomy trial. By the time we retired to the poster session and welcome reception, the exhibition hall was buzzing with excitement. The enthusiasm and cheerfulness were tangible, affecting everyone from the most junior researchers through to old hands. The sun shone on the entire conference, literally. I attribute the success to a huge amount of good fortune, to the efforts of a vast team and to the enthusiasm of every delegate. It would be unfair to single out any one contribution but I am convinced that it was those numerous individual contributions, offered generously and constructively, that allowed us to take advantage of the good fortune. To be present at this inaugural conference was reward enough for anyone working in stroke, because it was a once in a career occasion that we will each remember with great fondness. It was rather like a birth, a christening and a wedding, all rolled into one. Certainly, we have shown what a large and happy family we are in stroke medicine, and that Europe stands not alone but with societies and individuals all across the world. We will build on this success, we will maintain the spirit and principles that informed ESOC 2015, and I promise that by 10-12 May 2016 in Barcelona we will have another outstanding programme. For now, I express my sincere thanks to everyone for their support and hope that each of you left Glasgow with enthusiasm, new friendships and shared optimism for the future, for our patients and our specialty.
Mechanical thrombectomy improves outcomes in acute ischemic stroke.
Joint statement of the European Stroke Organisation (ESO), the European Society of Minimally Invasive Neurological Therapy (ESMINT) and the European Society of Neuroradiology (ESNR)
Stroke results from rupture or interruption of blood flow in brain vessels can lead to devastating consequences for patients, their families and society. Steady progress has been achieved in the last 20 years in stroke treatment through better prevention, establishment of stroke care units and the use of clot-busting drugs (intravenous thrombolysis).
Last week, new scientific evidence from four major stroke studies was presented at the International Stroke Conference in Nashville, USA. It proved that rapid mechanical thrombectomy (clot retrieval) improves patient function after acute ischemic stroke. To achieve this benefit, patients were treated by interventional neuroradiologists in stroke centers with multidisciplinary stroke teams. This treatment should be performed as rapidly as possible in conjunction with standard intravenous thrombolysis.
ESO, ESMINT and ESNR acknowledge this significant progress in acute stroke treatment and strongly support its application in appropriately selected patients in well equipped stroke centers by properly trained neurointerventionists. Further randomized trials of thrombectomy and more detailed analysis of the current trials will help to optimize patient selection and treatment algorithms.
Detailed guidelines on mechanical thrombectomy are currently being prepared by the key European societies involved in acute stroke care. Before these detailed guidelines become available, ESO, ESMINT and ESNR have jointly updated and support the consensus statement on thrombectomy by the ESO-Karolinska Stroke Update (see http://2014.strokeupdate.org/consensus-statement-mechanical-thrombectomy-acute-ischemic-stroke).
The European Stroke Organisation (ESO) is a society of stroke physicians, researchers, societies and patient organizations with the goal of optimizing and harmonizing the management of stroke in Europe by supporting medical education and stroke projects.

SITS endorses the ESOC – the European Stroke Organisation Conference in Glasgow 17-19 April 2015 – according to an announcement by SITS Chairman professor Nils Wahlgren today.
SITS usually arranges meetings for National Coordinators, SITS participants, workgroups and regional committees at large conferences and ESOC will be the conference for our meetings in Europe next year, Nils Wahlgren declared.
Nils Wahlgren concluded: We hope to see as many SITS members as possible in Glasgow, since it facilitates networking between those who use SITS.
The aim of the ICARO-3 study was to evaluate whether intra-arterial treatment, compared to intravenous thrombolysis, increases the rate of favourable functional outcome at 3 months in acute ischemic stroke and extracranial ICA occlusion. ICARO-3 was a non-randomized therapeutic trial that performed a non-blind assessment of outcomes using retrospective data collected prospectively from 37 centres in 7 countries. Patients treated with endovascular treatment within 6 h from stroke onset (cases) were matched with patients treated with intravenous thrombolysis within 4.5 h from symptom onset (controls). Patients receiving either intravenous or endovascular therapy were included among the cases. The efficacy outcome was disability at 90 days assessed by the modified Rankin Scale (mRS), dichotomized as favourable (score of 0-2) or unfavourable (score of 3-6). Safety outcomes were death and any intracranial bleeding. Included in the analysis were 324 cases and 324 controls: 105 cases (32.4 %) had a favourable outcome as compared with 89 controls (27.4 %) [adjusted odds ratio (OR) 1.25, 95 % confidence interval (CI) 0.88-1.79, p = 0.1]. In the adjusted analysis, treatment with intra-arterial procedures was significantly associated with a reduction of mortality (OR 0.61, 95 % CI 0.40-0.93, p = 0.022). The rates of patients with severe disability or death (mRS 5-6) were similar in cases and controls (30.5 versus 32.4 %, p = 0.67). For the ordinal analysis, adjusted for age, sex, NIHSS, presence of diabetes mellitus and atrial fibrillation, the common odds ratio was 1.15 (95 % IC 0.86-1.54), p = 0.33. There were more cases of intracranial bleeding (37.0 versus 17.3 %, p = 0.0001) in the intra-arterial procedure group than in the intravenous group. After the exclusion of the 135 cases treated with the combination of I.V. thrombolysis and I.A. procedures, 67/189 of those treated with I.A. procedures (35.3 %) had a favourable outcome, compared to 89/324 of those treated with I.V. thrombolysis (27.4 %) (adjusted OR 1.75, 95 % CI 1.00-3.03, p = 0.05). Endovascular treatment of patients with acute ICA occlusion did not result in a better functional outcome than treatment with intravenous thrombolysis, but was associated with a higher rate of intracranial bleeding. Overall mortality was significantly reduced in patients treated with endovascular treatment but the rates of patients with severe disability or death were similar. When excluding all patients treated with the combination of I.V. thrombolysis and I.A. procedures, a potential benefit of I.A. treatment alone compared to I.V. thrombolysis was observed.
