Rankin Scale Score (rankin + scale_score)
Selected AbstractsCopeptin: A novel, independent prognostic marker in patients with ischemic stroke,ANNALS OF NEUROLOGY, Issue 6 2009Mira Katan MD Objective Early prediction of outcome in patients with ischemic stroke is important. Vasopressin is a stress hormone. Its production rate is mirrored in circulating levels of copeptin, a fragment of provasopressin. We evaluated the prognostic value of copeptin in acute stroke patients. Methods In a prospective observational study, copeptin was measured using a new sandwich immunoassay on admission in plasma of 362 consecutive patients with an acute ischemic stroke. The prognostic value of copeptin to predict the functional outcome (defined as a modified Rankin Scale score of ,2 or ,3), mortality within 90 days, was compared with the National Institutes of Health Stroke Scale score and with other known outcome predictors. Results Patients with an unfavorable outcomes and nonsurvivors had significantly increased copeptin levels on admission (p <0.0001 and p <0.0001). Receiver operating characteristics to predict functional outcome and mortality demonstrated areas under the curve of copeptin of 0.73 (95% confidence interval [CI], 0.67,0.78) and 0.82 (95% CI, 0.76,0.89), which was comparable with the National Institutes of Health Stroke Scale score but superior to C-reactive protein and glucose (p <0.01). In multivariate logistic regression analysis, copeptin was an independent predictor of functional outcome and mortality, and improved the prognostic accuracy of the National Institutes of Health Stroke Scale to predict functional outcome (combined areas under the curve, 0.79; 95% CI, 0.74,0.84; p <0.01) and mortality (combined areas under the curve, 0.89; 95% CI, 0.84,0.94; p <0.01). Interpretation Copeptin is a novel, independent prognostic marker improving currently used risk stratification of stroke patients. Ann Neurol 2009;66:799,808 [source] Combined thrombolysis with abciximab and rtPA in patients with middle cerebral artery occlusionACTA NEUROLOGICA SCANDINAVICA, Issue 1 2010G. Gahn Background,,, In patients with acute middle cerebral artery (MCA) occlusion, recanalization rates with intravenous (IV) recombinant tissue plasminogen activator (rtPA) are limited. Aim, We evaluated the feasibility and safety of combined IV thrombolysis with abciximab and reduced dose rtPA in a 3- to 6-h time window. Methods,,, We prospectively (March 2002 to February 2005) studied patients with symptomatic MCA occlusion on computed tomography (CT) angiography and absence of major early ischemic changes (EIC) on non-contrast CT (NCCT) within 3,6 h from symptom onset. Patients were treated with IV abciximab and half-standard dose rtPA. Outcome parameters were symptomatic intracerebral hemorrhage (sICH), early clinical improvement and functional independence at discharge (modified Rankin Scale score , 2). Results,,, Of 13 patients, mean age was 62 ± 11 years, onset-to-treatment time 4.8 ± 0.9 h and median baseline National Institutes of Health Stroke Scale score 11 (interquartile range 6.5,13.5). sICH occurred in one patient (8%). We observed early clinical improvement in four patients (31%). Six patients (46%) were functionally independent at discharge. Conclusions,,, In patients with acute symptomatic MCA occlusion and absence of major EIC on NCCT, combined IV thrombolysis with abciximab and half-standard dose rtPA was feasible and seemed to be safe if applied within 3,6 h from symptom onset. [source] Ruptured symptomatic internal carotid artery dorsal wall aneurysm with rapid configurational change.EUROPEAN JOURNAL OF NEUROLOGY, Issue 10 2010Clinical experience, management outcome: an original article Background:, Aneurysms located at non-branching sites, protruding from the dorsal wall of the supraclinoid internal carotid artery (ICA) with rapid configurational changes, were retrospectively reviewed in effort to identify and characterize these high-risk aneurysms. Methods:, A total of 447 patients with 491 intracranial aneurysms were treated from March 2005 to August 2008, and of these, eight patients had ICA dorsal wall aneurysms. Four of them suffered subarachnoid hemorrhage (SAH), and all had aneurysms undergoing rapid configuration changes during the treatment course. Digital subtraction cerebral angiography (DSA) performed soon after the SAH events. Data analyzed were patient age, sex, Hunt and Kosnik grade, time interval from first DSA to second DSA, aneurysm treatment, and modified Rankin scale score after treatment for 3 months. Success or failure of therapeutic management was examined among the patients. Results:, Digital subtraction cerebral angiography showed only lesions with small bulges in the dorsal walls of the ICAs. However, the patients underwent DSA again for re-bleeding or for post-treatment follow-up, confirming the SAH source. ICA dorsal wall aneurysms with rapid growth and configurational changes were found on subsequent DSA studies. Conclusions:, Among the four patients, ICA dorsal wall aneurysms underwent rapid growth with configurational change from a blister type to a saccular type despite different management. ICA trapping including the lesion segment can be considered as the first treatment option if the balloon occlusion test (BOT) is successful. If a BOT is not tolerated by the patient, extracranial,intracranial bypass revascularization surgery with endovascular ICA occlusion is another treatment option. [source] Association of growth factors with arterial recanalization and clinical outcome in patients with ischemic stroke treated with tPAJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 7 2010T. SOBRINO Summary.,Background: Growth factors (GF) such as vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and granulocyte-colony stimulating factor (G-CSF) have been associated with greater efficacy of tissue plasminogen activator (tPA) in experimental studies. Objectives: To study the association of these GF with arterial recanalization and clinical outcome in patients with acute ischemic stroke treated with tPA. Methods: We prospectively studied 79 patients with ischemic stroke attributable to MCA occlusion treated with i.v. tPA within the first 3 h from onset of symptoms. Continuous transcranial color-coded sonography (TCCS) was performed during the first 2 h after tPA bolus to assess early MCA recanalization. Hemorrhagic transformation (HT) was classified according to ECASS II definitions. Good functional outcome was defined as a Rankin scale score of 0,2 at 90 days. GF levels were determined by ELISA. Results: Mean serum levels of VEGF, G-CSF and Ang-1 at baseline were significantly higher in patients with early MCA recanalization (n = 30) (all P < 0.0001). In the multivariate analysis, serum levels of VEGF (OR, 1.03), G-CSF (OR, 1.02) and Ang-1 (OR, 1.07) were independently associated with early MCA recanalization (all P < 0.0001). On the other hand, patients with parenchymal hematoma (PH) (n = 20) showed higher levels of Ang-1 (P < 0.0001). Ang-1 (OR, 1.12; P < 0.0001) was independently associated with PH, whereas patients with good outcome (n = 38) had higher levels of G-CSF (P < 0.0001). G-CSF was independently associated with good outcome (OR, 1.12; P = 0.036). Conclusions: These findings suggest that GF may enhance arterial recanalization in patients with ischemic stroke treated with t-PA, although they might increase the HT. [source] Revascularization in acute ischaemic stroke using the penumbra system: the first single center experienceEUROPEAN JOURNAL OF NEUROLOGY, Issue 11 2009I. Q. Grunwald Background and purpose:, This is the first single center experience illustrating the effectiveness of the penumbra system (PS) in the treatment of large vessel occlusive disease in the arena of acute ischaemic stroke. The PS is an innovative mechanical thrombectomy device, employed in the revascularization of large cerebral vessel occlusions in patients via the utilization of an aspiration platform. Methods:, This is a prospective, non-randomized controlled trial evaluating the clinical and functional outcome in 29 patients with acute intra-cranial occlusions consequent to mechanical thrombectomy by the PS either as mono-therapy or as an adjunct to current standard of care. Patients were evaluated by a neurologist and treated by our in house interventional neuro-radiologists. Primary end-points were revascularization of the occluded target vessel to TIMI grade 2 or 3 and neurological outcome as measured by an improvement in the NIH Stroke Scale (NIHSS) score after the procedure. Results:, Complete revascularization (TIMI 3) was achieved in 21/29 (72.4%) of patients. Partial revascularization (TIMI 2) was established in 4/29 (13.8%) of patients. Revascularization failed in four (13.8%) patients. Nineteen (19) patients (65.5%) had at least a four-point improvement in NIHSS scores. Modified Rankin scale scores of ,2 were seen in 37.9% of patients. There were no device-related adverse events. Symptomatic intra-cranial hemorrhage occurred in 7% of patients. Conclusions:, The PS has the potential of exercising a significant impact in the interventional treatment of ischaemic stroke in the future. [source] |
