INTRODUCTION: Intravenous thrombolysis (IVT) is a standard treatment for both anterior circulation ischaemic stroke (ACIS) and posterior circulation ischaemic stroke (PCIS). Our aim was to evaluate the predictors for a good clinical outcome and intracerebral haemorrhage (ICH) in patients undergoing posterior circulation IVT based on the initially performed CT or MR imaging. METHODS: The study cohort consisted of 1643 consecutive patients with acute ischaemic stroke (1440 ACIS, 203 PCIS cases) who underwent IVT. ICH was classified according to the European Cooperative Acute Stroke Study (ECASS) I protocol. Clinical outcome was assessed using the modified Rankin scale (mRS). Early ischaemic signs and pre-existing structural signs were assessed. RESULTS: Good clinical outcomes (mRS 0-1) were noted in 45.3% of patients with PCIS, with a mortality rate of 14.8%. ICH was noted in 8.3%, and a large haemorrhage was found in 2.4% of patients. Some early ischaemic signs and pre-existing structural signs on initial CT/MR imaging correlated significantly with the 90-day clinical outcome. CONCLUSIONS: Early ischaemic signs and pre-existing structural signs should be considered during the assessment of patients with PCIS eligible for IVT. Tissue hypoattenuation on initial CT scans correlates with an increased risk of death. Similarly to anterior circulation, atrophy on initial MRI may negatively predict good clinical outcome in posterior circulation.

BACKGROUND AND PURPOSE: The main aim of the study was to document the occurrence and evolution of post-stroke spasticity (PSS). The secondary goal was to identify predictors for increases and decreases in PSS rates during 12 months of subsequent follow-up. METHODS: In a longitudinal, multicenter, prospective cohort study, assessments were done at 7 days (V1), 6 months (V2), and 12 months (V3) after stroke onset. A total of 307 consecutive patients from four comprehensive stroke centers with the first-ever stroke of carotid origin and the presence of motor deficit at day 7 were included. The demographic data, baseline characteristics, Barthel index, degree and pattern of paresis and muscle tone were evaluated and recorded. Spasticity was assessed using the modified Ashworth scale. RESULTS: Spasticity was present in 45.0% of patients at V1, in 49.5% at V2, and in 43.2% at V3. A significant number of patients experienced changes in spasticity between visits: increased/new occurrence of spasticity in 32.5% (V1 and V2) and in 13.6% (V2 and V3) of patients; decreased occurrence/disappearance of spasticity in 18.5% (V1 and V2) and in 18.3% (V2 and V3) of patients. The number of patients with severe spasticity increased throughout the year, from 2.6% to 13.0% (V2) and 12.5% (V3). CONCLUSIONS: Spasticity developed in almost half of the included patients. The degree of spasticity often changed over time, in both directions. The rate of severe spasticity increased during the first year, with the maximum at 6 months following stroke onset.

Background: Intravenous thrombolysis (IVT) is a standard treatment for both anterior circulation ischemic stroke (ACIS) and posterior circulation ischemic stroke (PCIS). PCIS is a clinical syndrome associated with ischemia-related changes in the territory of the posterior circulation arteries. Embolism is the most common stroke mechanism in posterior circulation. PCIS represents 12-19% of all IVT-treated strokes. Methods and Results: We searched the PubMed database for assessments of intracerebral hemorrhage (ICH) and clinical outcome in PCIS patients treated with IVT. ICH occurs in 0-6.9% of posterior ischemic stroke depending on the definition of symptomatic ICH, and any ICH in 17-23.4% of posterior ischemic stroke. For patients with PCIS, 38-49% have a favorable outcome (mRS 0-1) after IVT. Better clinical outcomes occur more often in patients with PCIS than in those with ACIS. The mortality rate among PCIS patients treated with IVT ranges from 9 to 19%; it does not differ significantly between PCIS and ACIS. Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

AIMS: The main aim of this study was to provide an estimate of the incidence and prevalence of spasticity following stroke in the internal carotid artery territory for Regional Stroke Centers in the Czech Republic. A secondary goal was to identify predictors for the development of spasticity. METHODS: In a prospective cohort study, 256 consecutive patients with clinical signs of central paresis due to a first-ever stroke were examined in the acute stage. All patients had primary stroke of carotid origin and paresis of the upper and/or lower limb for longer than 7 days after stroke onset. All were examined between 7-10 days after the stroke. We evaluated the degree and pattern of paresis, spasticity using the Modified Ashworth scale and the Barthel Index, baseline characteristics and demographic data. RESULTS: Of 256 patients (157 males; mean age 69.9±12.4 years), 115 (44.9%) patients developed spasticity during the first 10 days after stroke onset. Eighty-three (32.5%) patients presented with mild neurological deficit (modified Rankin Scale 0 - 2) and 69 (27.0%) patients were bedridden. CONCLUSION: Spasticity was noted in 44.9% patients with neurological deficit due to first-ever stroke in the carotid territory in the first 10 days after stroke onset. Severe spasticity was rare.

Intravenous thrombolysis (IVT) is a standard treatment for anterior (ACS) and posterior circulation stroke (PCS). However, due to the low occurrence of PCS and of intracranial hemorrhage (ICH) in PCS, the knowledge about ICH predictors following IVT in PCS is sparse. Our aim was to identify predictors for ICH following IVT in PCS. The set consisted of 1281 consecutive ischemic stroke (IS) patients treated with IVT, out of which 158 (103 males; mean age 65.6 ± 12.3 years) had PCS. Collected data include baseline characteristics, common stroke risk factors, pre-medication, stroke severity, admission blood glucose level, blood pressure and treatment with intravenous antihypertensive therapy before and during IVT, occlusion of arteries, recanalization rate, time to treatment, and clinical outcome at day 90. Overall, 11 (7%) patients had ICH. Atrial fibrillation (p = 0.004), neurological deficit at time of treatment in the National Institutes of Health Stroke Scale (p = 0.016), decreased level of consciousness (p = 0.003), occlusion of basilar artery (p = 0.007), occlusion of PCA (p = 0.001), and additional endovascular therapy (p = 0.001) were identified by logistic regression analysis as significant predictors for ICH in PCS. Patients with ischemic lesion in the brainstem, occlusion of vertebral artery, or absence of basilar and posterior cerebral artery occlusion might be considered for treatment with IVT even in borderline cases. Those patients seem to have less frequently favorable outcomes without an increase in ICH rate. Time to IVT in PCS seems not to influence ICH risk or chances for favorable outcomes as significantly as it does in ACS.

BACKGROUND: Intravenous thrombolysis is considered to be the standard specific reperfusion therapy in acute ischemic stroke in both anterior and posterior cerebral circulation. AIMS: Our aim was to evaluate the 90-day outcome and rate of intracranial hemorrhage after recombinant tissue plasminogen activator administration in posterior circulation stroke and to compare the intracranial hemorrhage risk for posterior circulation stroke and anterior circulation stroke. METHODS: The set consisted of 877 consecutive acute ischemic stroke patients (777 anterior circulation stroke; 100 posterior circulation stroke) who underwent intravenous thrombolysis with recombinant tissue plasminogen activator in a standard dose of 0·9 mg/kg. The role of following factors was assessed: presenting characteristics, intracranial hemorrhage classification according to ECASS I, mortality, and 90-day clinical outcome assessed using the modified Rankin scale. RESULTS: Good clinical outcomes (modified Rankin scale 0-2) were noted in 59% of posterior circulation stroke patients, with a mortality rate of 19%. Intracerebral hemorrhage was significantly less frequent in posterior circulation stroke than in anterior circulation stroke patients (5·1 vs. 17·2%; P = 0·002). The risk of large hemorrhage (parenchymal hematoma 1 and 2) was 5·2 times higher in anterior circulation stroke patients (P = 0·007). The following additional statistically significant differences were found between posterior circulation stroke and anterior circulation stroke patients: median age, male gender, presence of atrial fibrillation, hyperlipidemia, median time to treatment, and median blood glucose level on admission. CONCLUSIONS: Our study suggests that posterior circulation stroke is associated with a lower risk of intracranial hemorrhage than anterior circulation stroke is.

AIM: To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome. MATERIALS AND METHODS: This retrospective, multi-centre study comprised 72 acute ischaemic stroke patients (51 males; mean age 59.1 ± 13.3 years) with radiologically confirmed BAO. The following data were collected: baseline characteristics, risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, localization of occlusion, time to therapy, recanalization rate, post-treatment imaging findings. Thirty- and 90-day outcomes were evaluated using the modified Rankin scale with a good clinical outcome defined as 0-3 points. RESULTS: Successful recanalization was achieved in 94.4% patients. Stepwise binary logistic regression analysis identified the presence of arterial hypertension (OR = 0.073 and OR = 0.067, respectively), National Institutes of Health Stroke Scale (NIHSS) at the time of treatment (OR = 0,829 and OR = 0.864, respectively), and time to treatment (OR = 0.556 and OR = 0.502, respectively) as significant independent predictors of 30- and 90-day clinical outcomes. CONCLUSION: Data from this multicentre study showed that multimodal EVT was an effective recanalization method in acute BAO. Bridging therapy shortens the time to treatment, which was identified as the only modifiable outcome predictor.

OBJECTIVE: to identify predictors of good outcome in acute basilar artery occlusion (Bao). Background: acute ischemic stroke (aiS) caused by Bao is often associated with a severe and persistent neurological deficit and a high mortality rate. METHODS: the set consisted of 70 consecutive aiS patients (51 males; mean age 64.5 +/- 14.5 years) with Bao. the role of the following factors was assessed: baseline characteristics, stroke risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, estimated time to therapy procedure initiation, treatment method, recanalization rate, change in neurological deficit, post-treatment imaging findings. 30- and 90-day outcome was assessed using the modified rankin scale with a good outcome defined as a score of 0- 3. RESULTS: the following statistically significant differences were found between patients with good versus poor outcomes: mean age (54.2 vs. 68.9 years; p=0.0001), presence of arterial hypertension (52.4% vs. 83.7%; p=0.015), diabetes mellitus (9.5% vs. 55.1%; p=0.0004) and severe stroke (14.3% vs. 65.3%; p=0.0002), neurological deficit at time of treatment (14.0 vs. 24.0 median of national institutes of health Stroke Scale [nihSS] points; p=0.001), successful recanalization (90.0% vs. 54.2%; p=0.005), change in neurological deficit (12.0 vs. 1.0 median difference of nihSS points; p=0.005). Stepwise binary logistic regression analysis identified age (or=0.932, 95% Ci=0.882-0.984; p=0.012), presence of diabetes mellitus (or=0.105, 95% Ci=0.018-0.618; p=0.013) and severe stroke (or=0.071, 95% Ci=0.013-0.383; p=0.002) as significant independent negative predictors of good outcome. CONCLUSIONS: in the present study, higher age, presence of diabetes mellitus and severe stroke were identified as significant independent negative predictors of good outcome.

BACKGROUND: Acute basilar artery occlusion (BAO) is relatively infrequent form of acute ischemic stroke associated with severe and persisting neurological deficit and high mortality rate (to 86%). Early recanalization is essential for good clinical outcome but the most effective treatment approach remains unestablished. Several treatment strategies are currently available but their safety and efficacy have only been tested in retrospective/prospective case series. Randomized controlled trials (RCTs) are lacking. METHODS AND RESULTS: We searched the PubMed database for assessments of recanalization rate and clinical outcome in BAO patients treated with various treatment methods. The results show that antithrombotics are least effective while specific reperfusion therapies including intravenous thrombolysis (IVT) and various types of intra-arterial therapy (IAT) are more so. Less than half of BAO patients reach independent outcome following IVT with a recanalization rate 52-78%. Even though IAT recanalizes BAO more frequently (in up to 100%), the higher recanalization rate is not necessarily associated with better outcome. CONCLUSIONS: Good clinical outcome is strongly dependent on recanalization time. Thus, the concept of bridging therapy, combining widely available IVT with IAT, was introduced and is usually considered a rescue strategy in non-responders to IV alteplase. A trend to better outcome in patients treated with bridging therapy in some studies, has to be confirmed by large RCTs.
