    L'Ă©valuation de l'unitĂ© neuro-vasculaire et de la filiĂšre "thrombolyse" au CHU d'Angers semblait indispensable 4 ans aprĂšs son ouverture. L'objectif Ă©tait d'Ă©valuer la prise en charge des patients victimes d'un AVC ischĂ©mique ou d'un AIT entre mai et novembre 2012 afin d'optimiser son fonctionnement. Concernant la filiĂšre thrombolyse, on note des dĂ©lais de prise en charge proches des recommandations internationales notamment pour les dĂ©lais arrivĂ©e-imagerie et arrivĂ©e-dĂ©but de thrombolyse pour les patients pris en charge sur Larrey en comparaison avec une prise en charge au SAU. Cependant, nous notons un dĂ©lai prĂ©-hospitalier encore trop long. Concernant la prise en charge en unitĂ© neuro-vasculaire, celle-ci permet, en accord avec les donnĂ©es de la littĂ©rature, une rĂ©duction des complications en comparaison avec une prise en charge en unitĂ© d'hospitalisation conventionnelle. Cependant on note certaines faiblesses concernant le bilan Ă©tiologique souvent incomplet Ă  la sortie d'hospitalisation du patient et des longs dĂ©lais pour la rĂ©alisation des examens aprĂšs la sortie, notamment pour l'IRM cĂ©rĂ©brale et l'Ă©chographie cardiaque. Cette Ă©tude est extrĂȘmement encourageante et montre de vĂ©ritables progrĂšs en terme de prise en charge des patients prĂ©sentant un AVC. L'unitĂ© neuro-vasculaire du CHU d'Angers a su au cours des 4 derniĂšres annĂ©es se dĂ©velopper et occuper une place indispensable au sein du service de neurologie, du CHU mais aussi de la rĂ©gion.The evaluation of the neurovascular unit and die "thrombolysis" CHU d'Angers seemed necessary four years after its opening. The objective was to evaluate the management of patients who have suffered an ischemic stroke or TIA between May and November 2012 in order to optimize its operation.On thrombolysis sector, there deadlines care closer to international recommendations including the arrival-time imaging and arrival-early thrombolysis for patients supported on Larrey compared with care at UAA. However, we note a too long pre-hospital delay. Regarding support in neurovascular unit, it allows, in agreement with literature data, a reduction in complications compared with care in conventional hospital unit. However there is some weaknesses in the often incomplete in the hospital patient discharge and long delays in completion of the reviews after the release etiologic, including brain MRI and echocardiography. This study is extremely encouraging and shows real progress in terms of care for stroke patients. The Stroke Unit of the University Hospital of Angers knew in the past four years to develop and occupy a vital place in the Department of Neurology, University Hospital but also in the region.ANGERS-BU MĂ©decine-Pharmacie (490072105) / SudocSudocFranceF

    cĂ©rĂ©brospinal de 3 des protĂ©ines impliquĂ©es dans la maladie d Alzheimer (MA) T-Tau (tau total), P-tau (tau phosphorylĂ©) et AbĂ©ta42 (Ab42) sont proposĂ©es comme un des nouveaux critĂšres pour ce diagnostic.Nous avons voulu confirmer la place du ratio Ab42/Ab40 en pratique clinique. Nous avons Ă©tudiĂ© les biomarqueurs Ab42, Ab40 et P-tau chez 165 patients avec une MA (n=77), une autre dĂ©mence (OD, n=30), un mild cognitive impairment (n=4), MCI ayant Ă©voluĂ© en MA (n=15), MCI avec une part vasculaire (n=3), dĂ©mence Ă  corps de Lewy (n=8), atrophie focale (n=9) et des patients prĂ©sentant une dĂ©mence d origine non dĂ©gĂ©nĂ©rative (ND, n=19). Les patients MA Ă©taient significativement diffĂ©rents des patients ND en utilisant la moyenne de P-tau, Ab42 et du ratio Ab42/Ab40, de mĂȘme pour la comparaison des patients MA et OD. La sensibilitĂ© Ă©tait de 96 %, la spĂ©cificitĂ© de 63 %, la valeur prĂ©dictive positive de 90 %, la valeur prĂ©dictive nĂ©gative de 80 % pour diffĂ©rencier les groupes MA et ND. L'originalitĂ© de cette Ă©tude repose sur le caractĂšre homogĂšne de l'analyse clinique et biochimique. Ce ratio permet de distinguer le groupes MA du groupe ND. Toutefois il manque de spĂ©cificitĂ© Ă  l'Ă©chelle individuelle. Des pistes sont proposĂ©es pour combiner diffĂ©rents biomarqueurs afin d'amĂ©liorer cette spĂ©cificitĂ©.ANGERS-BU MĂ©decine-Pharmacie (490072105) / SudocSudocFranceF

    Sténose du sinus transverse et hypertension intracrùnienne idiopathique (aspects diagnostiques, pronostiques et thérapeutiques)

    Lors de la réalisation d imagerie cérébrale, une sténose du sinus transverse (SST) est fréquemment découverte chez les sujets présentant une hypertension intracrùnienne idiopathique (HII), pathologie d étiologie inconnue touchant préférentiellement les jeunes femmes obÚses. Nous avons repris les données cliniques et radiologiques des 26 sujets ayant consulté pour HII dans le service de neurologie sur 69 mois. La prévalence de la SST était de 57% dont 38% à caractÚre bilatéral. Chez les sujets présentant une SST, la présentation clinique était plus sévÚre, sans corrélation avec les valeurs de pression d ouverture du liquide céphalo-rachidien. Parmi les 18 sujets suivis, il existait une amélioration clinique et une stabilité des signes radiologiques, la présence d une SST initiale n étant pas associée à un caractÚre évolutif spécifique. Malgré son caractÚre rétrospectif et sa puissance limitée, cette étude monocentrique et exhaustive confirme la prévalence significative de la SST dans l HII et sa possible association à des formes cliniques plus sévÚres. La SST est-elle cause ou conséquence de l HII ? Sa place dans la physiopathologie de l HII reste débattue. La présence d une SST fait néanmoins discuter de nouvelles approches thérapeutiques telles que le stenting, dont la place reste à définir dans le traitement de l HII.Transverse sinus stenosis (TSS) is a radiological sign identified in the majority of patients with idiopathic intracranial hypertension (IIH), pathology of unknown aetiology, typically affecting young obese women. We studied clinical and radiological data of 26 patients who consulted for IIH in our department of neurology during 69 months. The prevalence of TSS was 57%, 38% of these were bilateral TSS. Clinical signs were more severe among patients with TSS but these signs were not correlated with a highter opening pressure of cephalo-spinal fluid. Eighteen patients were followed, clinical signs improved whereas radiological signs did not change. The presence of TSS was not associated with specific evolution. Despite its retrospective nature, this exhaustive and monocentric study confirm the highter prevalence of TSS in IIH and a possible association with more severe clinical forms. Cause or result of IIH ? The place of TSS in the physiopathology of IIH is still discussed. The significative prevalence of TSS opens the way to new treatments such as stenting of TSS which place among more conventionnal treatments of IIH is not actually well-defined.ANGERS-BU Médecine-Pharmacie (490072105) / SudocSudocFranceF

    Effect of general anaesthesia on functional outcome in patients with anterior circulation ischaemic stroke having endovascular thrombectomy versus standard care: a meta-analysis of individual patient data

    Background: General anaesthesia (GA) during endovascular thrombectomy has been associated with worse patient outcomes in observational studies compared with patients treated without GA. We assessed functional outcome in ischaemic stroke patients with large vessel anterior circulation occlusion undergoing endovascular thrombectomy under GA, versus thrombectomy not under GA (with or without sedation) versus standard care (ie, no thrombectomy), stratified by the use of GA versus standard care. Methods: For this meta-analysis, patient-level data were pooled from all patients included in randomised trials in PuMed published between Jan 1, 2010, and May 31, 2017, that compared endovascular thrombectomy predominantly done with stent retrievers with standard care in anterior circulation ischaemic stroke patients (HERMES Collaboration). The primary outcome was functional outcome assessed by ordinal analysis of the modified Rankin scale (mRS) at 90 days in the GA and non-GA subgroups of patients treated with endovascular therapy versus those patients treated with standard care, adjusted for baseline prognostic variables. To account for between-trial variance we used mixed-effects modelling with a random effect for trials incorporated in all models. Bias was assessed using the Cochrane method. The meta-analysis was prospectively designed, but not registered. Findings: Seven trials were identified by our search; of 1764 patients included in these trials, 871 were allocated to endovascular thrombectomy and 893 were assigned standard care. After exclusion of 74 patients (72 did not undergo the procedure and two had missing data on anaesthetic strategy), 236 (30%) of 797 patients who had endovascular procedures were treated under GA. At baseline, patients receiving GA were younger and had a shorter delay between stroke onset and randomisation but they had similar pre-treatment clinical severity compared with patients who did not have GA. Endovascular thrombectomy improved functional outcome at 3 months both in patients who had GA (adjusted common odds ratio (cOR) 1·52, 95% CI 1·09–2·11, p=0·014) and in those who did not have GA (adjusted cOR 2·33, 95% CI 1·75–3·10, p<0·0001) versus standard care. However, outcomes were significantly better for patients who did not receive GA versus those who received GA (covariate-adjusted cOR 1·53, 95% CI 1·14–2·04, p=0·0044). The risk of bias and variability between studies was assessed to be low. Interpretation: Worse outcomes after endovascular thrombectomy were associated with GA, after adjustment for baseline prognostic variables. These data support avoidance of GA whenever possible. The procedure did, however, remain effective versus standard care in patients treated under GA, indicating that treatment should not be withheld in those who require anaesthesia for medical reasons
