Five recent randomized controlled trials provided clear evidence that endovascular thrombectomy (EVT) improves outcomes after acute ischemic stroke caused by large vessel occlusions (LVOs), [1][2][3][4][5] and current guidelines recommend EVT in addition to intravenous thrombolysis (IVT) within 4.5 hours among patients with anterior circulation strokes and LVO. 6,7 Patients eligible for IVT should receive it without delay even if EVT is being considered, but the particular benefit of IVT is not yet well established. Moreover, in the real world, a significant proportion of acute ischemic stroke patients receive IVT at local stroke centers where EVT is not available. Such centers apply a drip and ship protocol when an EVT candidate is identified, with the necessary subsequent transfer causing a delayed puncture. In this context, building up evidence of the specific role of IVT when added to EVT among LVO patients is necessary to reorganize stroke systems of care accordingly. We compared direct EVT (dEVT) against combined IVT+EVT in patients with anterior circulation strokes caused by LVO. MethodsWe used data included in the SONIIA registry (Sistema Online d'Informació de l'Ictus Agut), a government-mandated, populationbased, externally audited, prospective database that includes all acute ischemic stroke patients treated with reperfusion therapies in the region Background and Purpose-Whether intravenous thrombolysis adds a further benefit when given before endovascular thrombectomy (EVT) is unknown. Furthermore, intravenous thrombolysis delays time to groin puncture, mainly among drip and ship patients. Methods-Using region-wide registry data, we selected cases that received direct EVT or combined intravenous thrombolysis+EVT for anterior circulation strokes between January 2011 and October 2015. Treatment effect was estimated by stratification on a propensity score. The average odds ratios for the association of treatment with good outcome and death at 3 months and symptomatic bleedings at 24 hours were calculated with the Mantel-Haenszel test statistic. Results-We included 599 direct EVT patients and 567 patients with combined treatment. Stratification through propensity score achieved balance of baseline characteristics across treatment groups. There was no association between treatment modality and good outcome (odds ratio, 0.97; 95% confidence interval, 0.74-1.27), death (odds ratio, 1.07; 95% confidence interval, 0.74-1.54), or symptomatic bleedings (odds ratio, 0.56; 95% confidence interval, 0.25-1.27). of Catalonia from January 2011. Further details of this registry have been published elsewhere. 8 Briefly, the database includes relevant baseline information (prestroke medical history, medications and functional status, time of stroke onset and hospital arrival, severity, time of neuro/ vascular imaging, IVT and groin puncture time, and complications) and the neurological situation at 24 to 36 hours post-treatment, including symptomatic bleedings. Outcome variables at 3 months are good outcome (modif...

Olfactory disorders after SAH caused by rupture of the ACoA are very frequent and were present in both treatment groups. Cerebral vasospasm and frontal lobe lesions are related to worse performance on an olfactory test in patients undergoing endovascular coil embolization.

Our study showed no significant differences between both stentrievers. Moderately high recanalization rates are possible with both, however larger series may depict safety-related variations.

Recent reports have indicated that mechanical thrombectomy may have the potential to treat acute ischemic stroke. This study aims to describe the safety and effectiveness of Trevo Retriever, using Stentriever technology, in revascularization of patients with acute ischemic stroke. METHODSProspective study evaluating the clinical, radiological, and functional outcome of 13 patients with an angiographically verified occlusion of the anterior cerebral circulation. All patients underwent thrombectomy with TR as monotherapy or in combination with intraarterial thrombolysis, within the first 8 hours from the onset of symptoms. Successful revascularization was defined as thrombolysis in cerebral ischemia grade 2a to 3. Good outcome was defined as modified Rankin Scale score ≤ 2. RESULTS Median baseline National Institutes of Health CONCLUSIONEarly clinical experience suggests that the TR can allow safe and effective revascularization in certain subjects with acute ischemic stroke.
