Background: Patients with M2-MCA occlusion are not always considered for endovascular treatment. We aimed to study patients with an M2 occlusion treated with endovascular procedures. Methods: We studied patients prospectively included in the SONIIA register (January 2011-December 2012), a mandatory and externally audited register that monitors quality of reperfusion therapies in Catalonia under routine practice conditions. Baseline characteristics including NIHSS and occlusion location were collected. Complete recanalization was defined as a post-procedure TICI>2a, dramatic recovery: NIHSS drop>10 points or NIHSS<2 and good outcome as mRS<3 at 3 months. 24 hours CT scan determined the presence of hemorrhagic transformation (ECASS criteria) and infarct volume. Results: Of the 571 registered patients that received endovascular treatment, 65 (11.4%) presented an M2 occlusion on initial angiogram: mean age 66±15, female 47.7% median pre-procedure NIHSS 16(IQR:6). Mean time from symptom onset to groin puncture was 289±195 minutes, 35 patients (54%) received iv tPA before the procedure. Patients were treated with mechanic thrombectomy (n=49, 75.4%), ia tPA (n=3, 4.6%), both (n=7, 10.8%) or only diagnostic angiogram (n=6, 9.2%) according to interventionalist preferences. Patients who achieved complete recanalization (78.5%) had more often dramatic improvement (48% Vs 14.8%, p=0.023) smaller infarct volumes (8 vs. 82cc, p=0.013) and better outcome (66.3% Vs 30%; p=0.032) than those who did not recanalize. Rate of SICH was 9%. Independent predictors of dramatic improvement was complete recanalization (OR: 0,169 p=0.03 CI95%: 0.034-0.838) adjusted for age and baseline NIHSS Independent predictors of good outcome at 3 months were age (OR 1.067 p=0.033 CI95%: 1.005-1132) and baseline NIHSS (OR: 1.162 p=0.007 CI95%: 1.041-1.297) Conclusion: Endovascular treatment of M2 MCA occlusion seems safe. Induced recanalization may double the chances to achieve a favourable outcome

In this article, we evaluate the effectiveness of Cone Beam Computed Tomography, through a case study, in assessing the complication of intracranial bleeding during an endovascular treatment of brain arteriovenous malformation when compared to Multislice-Detector Computed Tomography performed immediately after the procedure. The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.

Earl J, Pop O, Jefferies K, Agrawal N. Impact of neuropsychiatry screening in neurological in-patients: comparison with routine clinical practiceBackground: It is now well recognised that the rate of psychiatric comorbidity is high in patients with neurological disorders. Psychiatric comorbidity has a significant impact on quality of life and often goes undetected in routine clinical practice.Objectives: To compare the rate of detection of psychiatric illness in routine clinical practice with the prevalence of mental illness established using a dedicated screening programme at a regional neuroscience centre and to assess if the screening programme had any enduring impact on routine clinical practice after its completion.Methods: Consecutive admissions to a neurology ward in the 3-month period before (n = 160) and after (n = 158) a dedicated neuropsychiatric screening programme was carried out were identified. Case notes were then reviewed to establish if symptoms of mental illness were identified by the treating neurologists and if patients were referred for neuropsychiatric assessment. Rates of detection of neuropsychiatric problems and rates of referral for treatment were compared with those identified during the screening programme.Results: In routine clinical practice, over two 3-month study periods, psychiatric symptoms were identified in 23.7% of patients and only 10.6% received neuropsychiatric interventions. This is much lower as compared with rates identified (51.3%) and treated (51.3%) during dedicated screening. Detection of mood symptoms decreased from 14.7% pre-screening to 3.8% in the post-screening period.Conclusion: Rate of detection and treatment of neuropsychiatric problems remain low in neurology in-patients in routine clinical practice. Neuropsychiatric screening is effective but does not have sustained effect once it stops. Hence we suggest that active ongoing screening should be incorporated into routine practice.

Purpose: We investigated the prevalence and prognostic impact on outcome of any intracranial hemorrhage, hemorrhage morphology, type and volume in acute ischemic stroke patients undergoing mechanical thrombectomy. Methods: Prevalence of intracranial hemorrhage, hemorrhage type, morphology and volume was determined on 24h follow-up imaging (non contrast head CT or gradient-echo/susceptibility-weighted MRI). Proportions of good outcome (mRS 0-2 at 90 days) were reported for patients with vs. without any intracranial hemorrhage. Multivariable logistic regression with adjustment for key minimization variables and total infarct volume was performed to obtain adjusted effect size estimates for hemorrhage type and volume on good outcome. Results: Hemorrhage on follow up-imaging was seen in 372/1097 (33.9%) patients, among them 126 (33.9%) with hemorrhagic infarction (HI) type 1, 108 (29.0%) with HI-2, 72 /19.4%) with parenchymal hematoma (PH) type 1, 37 (10.0) with PH2, 8 (2.2%) with remote PH and 21 (5.7%) with extra-parenchymal/intraventricular hemorrhage. Good outcomes were less often achieved by patients with hemorrhage on follow-up imaging (164/369 [44.4%] vs. 500/720 [69.4%]). Any type of intracranial hemorrhage was strongly associated with decreased chances of good outcome ( adj OR 0.62 [CI 95 0.44 - 0.87]). The effect of hemorrhage was driven by both PH hemorrhage sub-type [PH-1 ( adj OR 0.39 [CI 95 0.21 - 0.72]), PH-2 ( adj OR 0.15 [CI 95 0.05 - 0.50])] and extra-parenchymal/intraventricular hemorrhage ( adj OR 0.60 (0.20-1.78) Petechial hemorrhages (HI-1 and HI-2) were not associated with poorer outcomes. Hemorrhage volume ( adj OR 0.97 [CI 95 0.05 - 0.99] per ml increase) was significantly associated with decreased chances of good outcome. Conclusion: Presence of any hemorrhage on follow-up imaging was seen in one third of patients and strongly associated with decreased chances of good outcome.

Purpose: Hemorrhagic transformation (HT) is a common and potentially devastating complication of ischemic stroke, however its prevalence, predictors, and outcome remain unclear. Early anticoagulation is thought to be a risk factor for HT which raises the clinical question when to (re)start anticoagulation in ischemic stroke patients who have a compelling indication, such as atrial fibrillation. We conducted a prospective cohort study to address this question and to identify association of hemorrhagic transformation with outcome measures in patients with atrial fibrillation in the setting of acute ischemic stroke. Materials and Methods: We performed a prospective study which enrolled consecutive patients admitted with acute ischemic stroke presenting to a single center over a three-year period. As part of the observational study, baseline clinical data and stroke characteristics as well as 3 month functional outcome were collected. For this sub-study, we restricted the analysis to subjects diagnosed with atrial fibrillation. CT and MRI scans were reviewed by experienced readers, blinded to clinical data, to assess for hemorrhagic transformation (using ECASS 2 criteria), microbleeds and infarct volumes in both admission and follow-up scans. Clinical and outcome data were analyzed for association with hemorrhagic transformation. Results: Of 94 patients, 63 had a history of atrial fibrillation (67.0%) and 31 had newly discovered atrial fibrillation (33.0%). We identified HT in 3 of 94 baseline scans (3.2%) and 22 of 48 follow-up scans (45.8%) obtained a median of 3 days post-stroke. In-hospital initiation of either anti-platelet (n = 36; OR 0.34 [95% CI 0.10-1.16], p-value = 0.09) or anticoagulation with unfractionated intravenous heparin or low molecular weight heparin (n = 72; OR 0.25 [95% CI 0.06-1.15], p-value = 0.08) was not associated with HT. Initial NIH Stroke Scale (NIHSS) score (median 13.0 [IQR 15.0] vs. 7.0 [IQR 10.0], p-value = 0.029) and baseline infarct volume (median 17 [IQR 42.03] vs. 5 [IQR 10.95], p-value = 0.011) were significantly higher in patients with HT compared to those without. Hemorrhagic transformation was associated with a significantly higher 48-hour median NIHSS score (20 [IQR 3.0] vs. 2 [IQR 3.25], p-value = 0.007) and larger final infarct volume (81.40 [IQR 82.75] vs. 9.95 [IQR 19.73], p-value < 0.001). Finally, we found a trend towards poorer 3-month modified Rankin Scale scores in subjects with HT (OR 11.25 [95% CI 0.97-130.22], p-value = 0.05). Conclusion: In patients with atrial fibrillation, initial NIHSS score and baseline infarct volume are associated with hemorrhagic transformation in acute ischemic stroke. Early initiation of antithrombotic therapy was not associated with hemorrhagic transformation. Patients with hemorrhagic transformation were found to have a poorer short and long term outcome and larger final infarct volumes.

Background: Primary Stroke Centers (PSC) provide better acute stroke care than non-PSC hospitals, including faster times to imaging and lytic treatment, and higher rates of lytic delivery. Nationwide less than 1 in 3 hospital has achieved this designation. We aimed to determine the extent to which the better performance at PSC is driven by improvements within hospitals after PSC designation versus better baseline hospital care among facilities seeking PSC certification. Methods: From 2005 to 2012, the NIH Field Administration of Stroke Therapy -Magnesium (FAST-MAG) Phase 3 clinical trial enrolled subjects with likely stroke within 2 hours of onset in a study of prehospital start of a neuroprotective agent. Subjects were routed to 59 community and academic centers in Los Angeles and Orange Counties. Of the original 59 centers, 39 eventually achieved PSC status during the study period. Each subject was classified as enrolled at a PSC before certification (pre-PSC), at a PSC post certification (post-PSC), or at a hospital that never achieved PSC (non-PSC). Results: Of 1700 cases, 529 (31%) were enrolled at pre-PSC, 856 (50%) at post-PSC, and 315 (19%) at non-PSC hospitals. Mean time in minutes from ED arrival to first scan was 33 minutes at post-PSC, 47 minutes at pre-PSC and 49 at non-PSCs [p<0.001 by Mann-Whitney]. Among cases of cerebral ischemia (CI) [N=1223], rates of TPA utilization were 43% at post-PSC, 27% at pre-PSC and 28% at non-PSC hospitals [p<0.001 by X2]. Time in minutes from ED arrival to thrombolysis in treated cases was 71 at post-PSC, 98 at pre-PSC, and 95 at non-PSC hospitals [p<0.001 by Mann-Whitney]. Hospitals that achieved PSC showed improvements in pre-PSC and post-PSC performance on door to imaging time, from 47 to 33 minutes [p=0.014]; percent TPA use in CI, from 27% to 43% [p<0.001], and reduced door-to-needle times, from 98 to 71 minutes [p=0.003]. There was no difference in time to imaging [47 vs. 49 minutes], time to thrombolysis [98 vs. 95 minutes] and percent TPA use [27% vs. 28%] between pre-PSC hospitals and non-PSC hospitals. Conclusions: Better performance of Primary Stroke Centers on acute care quality metrics is primarily driven by a beneficial impact of the PSC-certification process, and not better performance prior to seeking PSC status.

Purpose: In this post-hoc analysis of the ESCAPE-NA1 trial, we investigated the prevalence of deep grey matter infarcts and their influence on clinical outcome. Methods: Infarcts on 24 hour follow up imaging (non contrast head CT or diffusion-weighted MRI) were categorized as predominantly deep grey matter infarcts (caudate and/or lentiform nucleus infarcts with sparing of the superficial grey matter and white matter) vs. other infarcts. Total infarct volume was manually segmented in all patients. When MRI follow-up was available, deep grey matter and grey matter infarct volumes were segmented separately. Multivariable logistic regression with adjustment for key minimization variables and by infarct volume was used to assess the association of predominantly deep grey matter infarcts and good outcome. Results: Of the 1026 included patients, 316 (30.8%) had predominantly deep grey matter infarcts. Cumulative proportions of good outcome for overall, grey matter, deep grey matter, and superficial grey matter infarct volumes are shown in the figure. Good outcomes were more frequently achieved in patients with predominantly deep grey matter infarcts (239/316 [75.6%] vs. 374/704 [53.1%]). Deep infarcts were tightly correlated with infarct volume (Pearson rho -0.35) and in multivariable analysis deep grey matter infarcts were predictive of outcome overall; when examined in volume percentiles, there was no effect of deep infarct location. Conclusion: Predominantly deep grey matter infarcts are associated with good outcomes. Deep grey matter infarct location favorable prognosis is associated with small overall infarct size.
